Camera Lens Mounts - Everything You Need to Know About Lens Mounts (2022)

With practically all camera manufacturers having launched several different camera systems, there seems to be quite a bit of confusion among photographers in regards to camera lens mounts. This is especially true for things like “throat size” and “inner diameter”, where different measurements are used to wrongly quantify a mount’s potential. Unfortunately, there is a lot of misinformation out there regarding mounts and their exact sizes, which is why I decided to write a detailed article talking about different mounts, their differences and take more precise measurements for different systems to present accurate information.

What is a Lens Mount?

Simply put, a lens mount is an opening of a specific size on an interchangeable lens camera that allows attaching lenses designed for that mount. Although in the early days of photography lenses were only mechanically attached to cameras without any communication between the two, with the rise of automatic metering and autofocus systems, it was necessary to create electronic contacts on both cameras and lenses to allow them to communicate with each other. As a result, a lens mount became more than just a physical hole, but more like an interface between lenses and cameras.

Today, practically every lens mount for photography is a bayonet mount (the name “bayonet” comes from the type of fitting soldiers used on their rifles to quickly mount bayonets), where three to four tabs are used to lock a lens tightly in place, but other lens attachment systems have been used in the past, such as screw-threaded lock and breech-lock. With a bayonet mount, one aligns a marked section of a lens (typically a colored dot) with the marked section on a camera body, then after coupling the two, twists the lens either in clockwise or counter-clockwise direction (depending on the brand/mount) until it locks into place.

The locking mechanism is mechanical, with a spring-loaded pin locking the lens in place in its proper position, requiring the pin to be retracted when a lens needs to be detached (which is done using a button next to the camera mount). The bayonet mount has a number of advantages compared to other mounts, which is why they are the most popular today. First, it makes it quick and easy to attach and detach lenses. Second, it allows for a tight and precise fit, which is especially important when shooting with modern high-resolution cameras, as any sort of wobble or play could end up negatively affecting parts of the image. And lastly, a bayonet mount also allows for easy incorporation of electronic contacts between lenses and cameras to enable two-way communication.

Due to the proprietary nature of all camera mounts, each one of them can differ in mounting direction, mount size, flange distance, number of electronic contacts and even where the electronic contacts are physically placed. Let’s take a look at each in more detail.

Mounting Direction

While most lens mounts require attaching lenses by twisting them clockwise, some brands like Nikon have a reversed way of doing it. On one hand, it does not matter which direction a lens is mounted or dismounted, but on the other hand, it might cause some confusion and might take time to get used to it, especially for those who decide to switch brands. Below is a table that summarizes the mounting direction of lenses among the popular camera brands.

Please note that the mounting direction is relative to the front view of the camera.

Mount Size (Throat Size, Inner and Outer Diameters)

When it comes to mount size, there are a few important measurements that need to be done correctly, especially when a lens mount is being compared to another one (as you want to compare apples to apples). There is throat size, inner diameter and outer diameter, and all of them mean different things. Let’s take a look at different measurement criteria and their differences.

(Video) Lens Mounts Explained: FocusEd

Throat Size

The throat size of a lens mount is the inner diameter of a mount, minus the tabs that are used to mount lenses. Throat size gives us a more accurate representation of the potential of the mount and is important for calculating the angle of incidence, which we will discuss below.

Take a look at the below image to understand how the throat size is measured on a system:

Camera Lens Mounts - Everything You Need to Know About Lens Mounts (3)

As you can see, the distance measured is between the two tabs on the inner side of the mount.

Inner Diameter

The inner diameter of a lens mount represents the size of the lens opening ignoring the tabs on the mount. This measurement is often provided by camera manufacturers to give us an idea of the overall size of the lens mount.

Below is the image of how the inner diameter of a lens mount is measured:

Camera Lens Mounts - Everything You Need to Know About Lens Mounts (4)

Please note that the measurement is taken of the outermost inner part of the mount here. Due to the small additional recess within the inner mount in the case of Nikon F, there is an additional loss of 0.5mm to clear it. Hence, while the inner diameter is 47mm as measured above, it is technically 46.5mm between the inner parts of the mount.

Outer Diameter

The outer diameter of a lens mount is the full diameter of the bayonet mount, which in most cameras represents the end of the metal mount. The outer diameter of the mount plays an important role in determining the approximate outer diameter of the rear part of a lens, as it must be able to wrap itself over the outer diameter.

Here is the image of how the outer diameter of a lens is measured:

Camera Lens Mounts - Everything You Need to Know About Lens Mounts (5)

Again, there is another small recess that is right below the outer part of the mount, but we do not measure the outer diameter from it.

Flange Distance

Flange distance, also known as “flange focal distance”, “flange back distance” or simply “register”, is the distance between the mounting flange (which is the outer part of the lens mount when viewed from the side) and the film/sensor plane. Just like different mounts have differences in throat size, inner and outer diameters, flange distances also often vary greatly between different camera systems.

Mount Size, Flange Distance and the Angle of Incidence

Now that we have defined the mount size and the flange distance, let’s talk about the pros and cons of large vs small mount sizes, as well as the impact of the flange distance on a system.

The size of the mount is an important factor in a camera system. Generally, a larger mount size allows for larger lenses that can provide more light to the sensor. Hence, faster lenses can be designed by optical engineers. At the same time, mount diameter is not the only variable that impacts lens design – flange distance is also equally important. Shorter flange distance allows lenses to be placed closer to the sensor, which in itself allows lens manufacturers to start building simpler, smaller, lighter and less expensive short-focus lenses instead of the retro focus types.

A shorter flange distance also allows designing thinner cameras, thus making them smaller and lighter compared to cameras with longer flange distances. In addition, it allows lens designers to place a more powerful actuator on lenses for faster autofocusing and makes it possible to adapt lenses from other camera systems with longer flange distances via adapters. Lastly, the throat diameter combined with flange distance determines the maximum possible angle of incidence of the marginal rays from the lens, which is important in designing lenses – generally, the larger the angle of incidence, the easier it is to make high-performance lenses.

One downside of a larger lens mount is lens size and weight issues. The larger the throat diameter, the larger the lens has to be at its mount point, which obviously does impact its overall thickness and weight as well. Also, the shorter flange distance can lead to increased vignetting or discoloration in the corners of an image (although this can be mitigated by making the lens design longer to simulate a longer flange distance), due to sensor microlenses not being able to pass enough light at extreme ray angles.

To understand the importance of a larger mount and a shorter flange distance, please check out the below video from a Nikon engineer that explains the benefits of the Nikon Z system when compared to Nikon F:

When adapting lenses from other mounts, it is important to point out that due to the proprietary nature of autofocus systems, differences in exchange of information between camera body and lens via electronic contacts (the number of which also vary from system to system) and other issues, most adapters end up being “dumb” adapters with manual controls, manufactured by third party companies. Camera manufacturers themselves often provide adapters with the release of shorter flange distance systems to be able to mount lenses from other camera mounts that they developed in the past, but they almost never provide adapters for competing systems.

In addition, some adapters are capable of changing the physical properties of lenses by using glass elements in them, while others make it possible to insert a lens filter (such as neutral density or polarizing filter), making it possible to use filters on wide-angle lenses with oversized front elements, without involving bulky filter mounting rigs and large filters. When adapting lenses from other systems, it is important to make sure that the target lens mount has a longer flange distance in order to be able to achieve infinity focus. Furthermore, the difference in flange distance between the source and the target system has to be big enough to have enough room for an adapter to sit between the lens and the camera for a dumb adapter. Smart adapters that can establish communication between the camera and the adapted lens must have even more legroom for contacts and electronics to fit between the two.

Camera Mount Comparison

Now that we have gone through all the terms and definitions, let’s go ahead and compare different camera mounts based on their throat and inner diameters, as well as flange distance and angle of incidence:

Note

To find the angle of incidence, I calculated the angle between the throat diameter and the top center of each system’s camera sensor. I assumed all full-frame sensors to be 24mm in height, the Fuji X camera sensor to be 15.6mm in height, and the Fuji G camera sensor to be 32.9mm in height (note that other websites sometimes do this calculation with inner mount diameter rather than the throat diameter, and they may calculate from a corner or the center of the camera sensor rather than the top center).

Frequently Asked Questions

Below is a list of FAQs related to lens mounts that I put together for our readers:

What are the different camera mounts?

While many camera mounts have existed in the past, the most popular camera mounts today are: Canon EF, Canon RF, Fujifilm X, Fujifilm G, Leica L, Leica M, Nikon F, Nikon Z, Pentax K and Sony E. Each one differs from each other by a combination of throat diameter and flange distance.

How do I know which lens mount my camera has?

Find your camera’s brand and model, then search for its manual online. The manual should contain information relative to the mount, as well as a list of compatible lenses. Another option is to look up the lens that is mounted on your camera – its description should contain the name of the mount.

Which lens mount is the best?

(Video) RED TECH | Lens Mounts

While all lens mounts have their strengths and weaknesses, lens mounts with the largest throat size and shortest flange distance typically provide the most flexibility for lens design. At the moment, Nikon Z, Canon RF and Leica L mounts have the largest throat diameter and shortest flange distance among full-frame cameras.

Are all Nikon lens mounts the same?

No, they are not. Nikon has two different lens mounts: Nikon F and Nikon Z. The former is for Nikon’s DSLR cameras, while the latter is for Nikon’s newer mirrorless cameras.

Are camera lenses universal?

Unfortunately, they are not. Aside from a couple of alliances, most camera manufacturers typically create their own proprietary mounts, resulting in many different lenses for different lens mounts. However, some third-party lens manufacturers make the same lens for different camera mounts.

Can you mount a Canon lens on a Nikon camera?

It depends on the lens mount. You cannot mount a Canon EF lens on a Nikon F camera, because the Canon EF mount has a shorter flange distance. However, it is technically possible to mount a Canon RF lens on a Nikon Z camera.

What is a lens mount adapter?

(Video) Identifying a camera lens mount Part II Minolta Nikon Konica Pentax

A lens mount adapter is a device that allows a lens from one camera mount to be used on a camera with a different mount. While some manufacturers provide lens mount adapters with full compatibility and autofocus features, most adapters are “dumb”, and cannot transmit electronic data.

Most lens mounts use a pin on the camera body that inserts into a hole on the lens to lock the lens in place.. The CPU contacts on the lens and lens mount connect together so that the camera can communicate information to the lens.. And so we today have a situation where cameras with different sensor sizes both use the same lens mount, and lenses designed for different sensor sizes both use the same lens mount.. On Canon EF-S lenses, they modified the mount on the lens slightly, so they cannot be mounted on a full frame camera with EF mount.. Example of a lens mount adapter, this one allows Pentax K mount lenses to be used on Micro four thirds mount cameras. As a general rule, a lens mount with a smaller flange distance can use lenses designed for use with a mount with a larger flange distance, provided the correct adapter is used.. However, you can (in some cases) get adapters that let you use a lens designed for a lens mount with a shorter flange distance than the mount your camera uses.

Also, camera manufacturers generally want to have their own lens mounts, which they don’t share with anyone else.. As such, there is no standardised lens mount on large format cameras.. Along with brand-specific mounts (Canon’s old FD, Nikon F), universal mount types also gained ground.. Became too small Flange distance is the distance between the lens mount and the sensor in a camera.. Cameras with shorter flange distances can be much smaller, as their mount doesn’t have to stick out far away.. The Canon RF mount has the same base pin layout as the EF mount, along with some extra pins.. Canon EF mount with default pin layout This is the distance between the rear lens element and the sensor.. It’s a universal mount, used in countless cameras and lenses released after the ’50s.. Lenses mounted with a bayonet fit perfectly, and there’s only one way to attach a lens.. Some lens mounts are direct successors to other mounts or sideline continuations.. It allows the mounting of all EF lenses, plus newly-designed crop-sensor lenses.. Generally, you can adapt lenses that have a flange distance at least 3-4mm longer than the mount you want to adapt it to.

However, as boring as the interface between your camera and lens might be, the significance of your camera's specific mount, along with which lenses can be used on your camera, which lenses can be adapted to your camera, and why some lenses work and others do not, can prove to be a more interesting subject that may even inform which camera or lens system you eventually buy.. A lens mount is a standard or proprietary interface used by camera and lens manufacturers to ensure a secure and accurate means for attaching a lens to a camera body.. Each camera system nowadays uses its own unique mount that limits compatibility between lenses and other manufacturers’ cameras, and also enables electronic communication between the lens and camera to achieve accurate focus and exposure.. Most lens mounts in current use are bayonet style, in which a lens is attached to the camera body by registering the lens in proper orientation with the camera body, then giving a slight twist of about 45-90° to lock the lens in place.. Breech-lock mounts are more closely related to bayonet mounts; however, they use a self-contained rotating ring on the lens itself to tighten the lens onto the camera body with friction.. Besides connecting a lens to a camera and sporting a certain design style, lens mounts also have a number of distinctions from manufacturer to manufacturer.. The number of tabs in a specific bayonet can vary from one manufacturer to another (although most use three tabs), the direction in which you rotate the lens to connect with the camera body varies among brands, and the incorporation of electronic contacts will also be unique to the camera and lens manufacturer.. This measurement, which describes the length from the mounting flange (the edge of the lens mount on the camera body) to the image sensor or film plane, varies from manufacturer to manufacturer, and is one of the true limiters of the interchangeability of lenses with specific cameras.. The flange focal distance of each camera system is factored into subsequent lens designs, and is a constant length used by each manufacturer to ensure accurate focus from a specific lens’s minimum focusing distance to infinity.. By having this shorter registration distance, you can theoretically mount any lens with a longer FFD on a camera with shorter FFD through the use of a lens adapter .. The lens adapter effectively serves to make up the difference in focal flange distance between the camera and lens—for example, a Nikon F lens to Sony E adapter makes up the difference of 28.5mm to provide the proper total 46.5mm of focal flange distance for a Nikon F-mount lens to achieve infinity focus.. While this is the ideal situation, to mount lenses with a longer FFD on cameras with a shorter FFD, adapters do exist that allow you to physically attach lenses with shorter FFD measurements to camera bodies with a longer FFD.. With this basic concept in mind, lens adapters can also be substantially more sophisticated and maintain electronic communication between the adapted lens and body through the use of dandelion chips, with some adapters even capable of retaining a lens’s autofocus and image-stabilization capabilities.. On the other hand, completely manual adapters will not convey any information between the camera and adapted lens, forcing you to manually focus and adjust the aperture settings on a lens, and work in manual or aperture-priority mode on the camera.. With the exception of Sony E-mount now being featured on full-frame cameras, these mounts typically correspond to crop-sensor sizes and, as such, are associated with terms like “crop factor” and “equivalent focal length.” This batch of lens adapters strives to make these terms somewhat moot by incorporating a condensing lens into their design to minimize, or in some cases eliminate, the crop factor and increase the amount of light reaching the sensor.

Canon EOS film and digital SLRs can, on the other hand, accept almost anything BUT a Canon FD lens with adapters: Nikon, OM, Pentax M42 Screw, and Leica SLR lenses can all be adapted.. – NIKON: The Nikon bayonet did not change when AF was introduced.. There are adapters for OM, Nikon, Pentax (both screw mount AND bayonet), Leica R and Minolta MD lenses to fit Olympus DSLR cameras.. For “Program” operation with some models, you will need a Series “A” or later lens.. The second “System Ring” allowed those same cameras to accept M42 screw mount lenses.. Unfortunately, I’ve never had a camera that fit this adapter ring.. With the correct mount, a “T” mount lens can fit anything.). The M44 screw thread was kept as part of the bayonet mount design, so that these lenses could still be used on later Miranda cameras.. There have never been any variations of this mount; every OM lens fits every OM camera ever made.. This is the Yashica/Contax lens mount.. I don’t own one of these, this photo was donated.

The quality and optical clarity of the lens is paramount, but you also have to consider the type of lens mount your camera has, and whether or not you require a fixed lens or zoom lens.. Zoom There are two different types of zoom capabilities: optical zoom or digital zoom.. This is different from a digital zoom.. Because real estate is expensive, studios are typically small and jam-packed, so wide angle lenses are used to make the environment look larger.. The size of the iris opening is the aperture of the lens.. The wider the aperture, the more light passes through the iris, the brighter the image will look.. You can control the depth of field by widening or narrowing the aperture – wide aperture can make the subject or object well focused, with background objects blurrier; smaller apertures help everything in the frame look more in focus.. MFT Lens Mount MFT (Micro Four Thirds) lens mount cameras can be a cost effective choice for house of worship broadcast, yet it has it’s disadvantages.. Churches who have been accustomed to using B4 or par-focal lenses are used to zooming all the way into an object, and if your back focus is set correctly you can zoom out all the way and the subject remains in-focus.. Another benefit to an MFT mount is that other lens styles (including B4 and PL lenses) can often be fitted to an MFT mount camera using adapters.. PL Lens Mount Arri PL (positive lock) lens mounts are designed more for cinema and digital film styles, developed for 16mm and 35mm motion picture cameras.. PL mount lenses are very precise, very expensive, and probably not the type of lens most houses of worship will be looking to purchase for their broadcast ministry.. However, PL mount lenses are becoming more affordable, and companies like Arri, Blackmagic Design, Canon, Hitachi, JVC, and Sony offer popular PL mount cameras, and/or adapters for PL mount lenses.. While it’s much more affordable to purchase consumer ‘fixed-lens’ or prosumer cameras with digital zooms, for many houses of worship this style of camera and lens will not offer the video quality required to run a professional-looking broadcast.. If you currently don’t have a budget for brand new lenses and you need to start somewhere, you may want to consider looking at eBay or other online resellers who offer a wide variety of used B4, MFT or PL lenses at affordable prices.

A C-mount without a lens within is known as a 1x C-mount and the only function is as an adaptor for the camera to the microscope to secure the camera to the system.. Cameras generally do not have T-mounts, therefore T adaptors or T2 adaptors must be used.. However, all microscope systems will have different requirements for the C-mount adaptor on the photoport side, therefore microscope C-mounts should be matched to the system itself and can not be interchanged between systems.

For most people, I recommend choosing one of the six most popular lens mounts: Nikon DX (APS-C DSLR), Canon EF-S (APS-C DSLR), Sony E-Mount (APS-C mirrorless), Micro four-thirds (mirrorless), Nikon FX (full-frame DSLR), or Canon EF (full-frame DSLR).. Nikon.. Nikon DSLR cameras have about 30% better image quality than the Canon equivalent at that price point.. Canon.. I recommend Sony E-mount APS-C mirrorless cameras to casual photographers and my friends who love gadgets.. I don’t often recommend Sony’s DSLR cameras because I believe Sony will soon abandon DSLR format and put its energy into its mirrorless cameras.. For example, the Olympus 35-100 f/2 ($2,500) is equivalent to a Canon or Nikon 70-200 f/4 ($1,300).. Fuji’s not popular enough to get lens support from Tamron and Sigma, which is a big drawback—you’re limited to the handful of lenses Fujifilm sells.. I hesitate to recommend many other lens mounts because they have limited lens support or I’m uncertain that the manufacturer will continue making new lenses and cameras in the future.. Note that Canon, Nikon, and Sony APS-C camera bodies can use same brand’s full-frame lenses, albeit with a drop in image quality.. If you want to use your Canon DSLR lenses on a mirrorless body, you should get the Canon EOS M.. If you don’t want to lose your investment in DSLR lenses but you do want to use a mirrorless body, I advise you to sell your DSLR lenses and put the proceeds towards native lenses.

Right from the start of the RF introduction, Canon was quick to implement several lenses into the line-up.. This year Canon announced the following with 2020/2021 releases.. Yes, this is not a lens for one of the new mounts introduced over the last two years.. Either way, as a Fuji user, I’ll be adding this to the wish list.

I mean a lens.. A lot of photographers prefer prime lenses to zoom lenses.. Tamron makes some very interesting lenses for both Canon and Nikon systems.. Sigma makes lenses not only for its own camera system but also for Nikon, Canon, and Sony.. Different manufacturers use different acronyms to denote the image stabilization technology on their lenses.. It is just that not all lenses have them.. This camera came with tiny focus sensors as well as paired with lenses that had focusing motors inside them.. Fast aperture will ensure that you are able to capture a reasonable amount of light even when there is not enough to go around.. Different photographers prefer different lenses for doing street photography.. Not everyone needs a second lens though.. There are some lenses like that.

The description for third-party lenses will say something like, “for Canon SLRs” or “for Nikon SLRs.” Here’s where it gets confusing: Canon and Nikon both sell camera bodies with different sensor sizes: compact and full-frame.. Like the full-frame camera bodies, EF lenses are designed for more professional purposes.. If you have a Canon compact DSLR, such as a T2, T3, T4, 7D, Rebel, Kiss, or anything with more than two numbers in the name (like 60D or 600D), you should choose Canon EF-S lenses whenever possible.. “Canon” means it’s designed for Canon SLRs.. You cannot use EF-S lenses on full-frame Canon cameras.. A typical Canon full-frame professional lens adds a couple of elements to the description: Because the sensor size is “EF,” rather than “EF-S,” the lens is designed for full-frame cameras.. Because it was introduced so much earlier than Canon’s, the original design relied on mechanical linkages between the body and lens to support focusing the lens and changing the lens aperture.. These lenses are designed for full-frame Nikon DSLRs, such as the D600, D700, D800, D3, and D4.. Like the full-frame camera bodies, FX lenses are designed for more professional purposes.. Either type of lens can be used on any Nikon body.. Most new Nikon lenses are the AF-S variety, which includes a focusing motor in the lens.. You might see other acronyms in Nikon lens descriptions, all of which you can ignore:. Like Canon and Nikon, Sony makes lenses optimized for cameras with compact sensors as well as full-frame lenses.. “DT” indicates a lens designed for Sony Alpha DSLRs with a smaller sensor size.. You might see other acronyms in Sony lens descriptions:

Focusing Less expensive are the point and shoot cameras with focus-free lenses in which the focus is permanently set.. The depth of field of any lens depends upon the focal length of the lens, the relative aperture and the distance between the object and the lens.. Lens quality and performance Performance of any lens depends on five factors: Sharpness, Color correction, Flare, Evenness of light distribution and Distortion.. Wide-angle lens A lens of focal length shorter than the standard lens is called a wide-angle lens.. Fix the hood on the camera lens for all types of photography and especially for against the-light pictures.

Before we get into the more technical discussion about the Nikon Z lenses, let’s first take another look at the advantages of the new Nikon Z mount and why it opens up new frontiers for Nikon that the Nikon F mount could not before.. To understand the differences between the Nikon Z and the Nikon F mounts, take a look at the below side-by-side images of the Nikon Z7 and the Nikon D850:. But that’s not the only difference – the Nikon Z mount has a flange distance (which is the distance between the mounting flange and the image sensor) of 16mm, which is significantly shorter than the 46.5mm flange distance on the Nikon F. This essentially means that the Nikon Z mount has a much larger angle of incidence, allowing to design high-performance lenses that were not possible before with the Nikon F mount.. With the Z-series cameras, Nikon announced three new Z mount lenses: Nikon Z 24-70mm f/4 S , Nikon Z 35mm f/1.8 S and Nikon Z 50mm f/1.8S , as well as the development of the fourth lens, the Nikon Z 58mm f/0.95 S Noct.. While the maximum aperture of the three released lenses might indicate that these are enthusiast-grade lenses (f/1.8 and f/4 lenses are typically enthusiast-grade lenses, while f/1.4 and f/2.8 lenses are pro-grade), that’s certainly not true!. In fact, the “S” line (which is marked by the silver-colored ring around the lens and a decorative “S” on the lens barrel, which apparently represents the first letter of various words as “Superior”, “Special” and “Sophisticated”, according to Nikon) is now the new “Pro” line of lenses, similar to the gold ring lenses that Nikon made for the F mount.. The new Nikon S-series lenses have a refreshed, all-black look that makes them look quite a bit different when compared to Nikon F gold ring lenses.. So if you are worried about the new Nikon 35mm f/1.8 S and 50mm f/1.8 S lenses costing more than their Nikon F counterparts, these are not comparable lenses by any means, as you will see further down below.. The new Nikon Z mount lenses no longer have the traditional mechanical control of focusing as we have seen on all Nikon F mount lenses (where turning the focusing ring physically moves and focuses lens elements).. While focus-by-wire implementations by some camera companies are often quite frustrating to use in the field due to issues related to attaining precise focusing, holding focus position when turning the camera on / off or when wanting to smoothly transition focusing when shooting videos, based on my limited experience with the Nikon Z-series cameras and lenses, I have to say that I was quite impressed by how smooth focusing felt when using Z mount lenses.. Instead of 8 contacts facing the camera on Nikon F (some Nikon F lenses have 10 contacts, but the last 2 contacts are reserved for teleconverter communication), the new Nikon Z mount lenses now communicate over 11 total contacts for more refined control and improved performance of lenses.. Nikon has already enabled customization of the focusing ring on the three Nikon S lenses, but none of these lenses yet feature buttons.. While many of us will be supplementing the Nikon Z-series cameras with the FTZ mount to keep on shooting with Nikon F lenses for now, the performance advantages of the Z-series lenses will definitely outweigh everything else in the long run.

Focal length - this defines how wide or zoomed-in a view the lens provides Aperture - expressed as 'F' or 'f/' this describes how much light the lens can gather and its ability to blur the image background Image Stabilization - some lenses include optical stabilization units to counteract the blurring effects of hand shake Format - describes the sensor size the lens is designed to work with Lens mount - determines whether the lens will physically fit your camera. The first number used to describe a lens is its focal length; in combination with the camera's sensor size, this defines the angle of view covered by the lens, with smaller 'mm' numbers indicating a wider angle or more 'zoomed out' view.. This means simply that an 18-55mm lens on an APS-C format camera covers the same angle of view as a 28-90mm lens does on a full-frame camera.. Each camera maker uses its own proprietary lens mount, meaning that lenses can't be swapped across brands; a Canon lens won't fit on a Nikon body, for example, and you'll cause damage to both lens and camera if you try..
