EFS lenses are designed for APS-C sensor cameras and will not work with a full frame camera such as the Canon 5D. There are a few ways to get around this, but none of them are ideal. The first is to use an adapter which will allow you to mount the EFS lens on the 5D body.
However, this will result in a loss of image quality due to the difference in sensor size. The second option is to use a crop factor when calculating your exposures, but this can be tricky and is not recommended. The third option is to buy an EF lens which is compatible with both APS-C and full frame cameras.
This is the best solution, but it can be expensive.
- Decide which lens you would like to use with your 5D camera
- Mount the lens onto the camera
- Turn on the camera and set it to MF (manual focus)
- Adjust the focus ring on the lens until the image is clear
- Take a picture!

Canon EF-S Lens on a Full Frame Body (5D Mark IV)
Can I Use Ef-S Lens on Canon 5D?
No, you cannot use an EF-S lens on a Canon 5D camera. The Canon 5D series of cameras uses a full frame sensor, while the EF-S lenses are designed for APS-C sensors found in Canon’s Rebel and xxD series cameras.
Do Ef-S Lenses Work on 5D Mark Iv?
No, EF-S lenses will not work on the 5D Mark IV. The EF-S lens mount is only compatible with Canon APS-C sensors, and the 5D Mark IV has a full frame sensor. You’ll need to use EF or RF lenses with the 5D Mark IV.
Do Ef-S Lenses Work on 5D Mark Iii?
No, EF-S lenses will not work on the 5D Mark III. The 5D Mark III uses a full frame sensor, while EF-S lenses are designed for use with APS-C sensors. While you can physically mount an EF-S lens on a 5D Mark III body, the camera will not be able to properly communicate with the lens and you will not be able to take any pictures.
What Lenses are Compatible With Canon 5D?
If you own a Canon 5D DSLR camera, you may be wondering what lenses are compatible with it. Here is a list of all the Canon EF and EF-S mount lenses that are compatible with the Canon 5D:

Efs to Ef Adapter
An EF to EF adapter is a device that allows you to mount an EF lens on an EF-S body. This can be useful if you have an EF lens that you want to use with an EF-S body, or if you want to use an EF-S lens on an EF body. The adapter does not change the optics of the lens, so there is no degradation in image quality.
There are a few things to keep in mind when using an EF to EFS adapter. First, the adapter will add a slight amount of length to the lens. This means that the minimum focus distance of the lens will be increased.
Second, because the adapter changes the registration distance of the lens, it is not possible to use autofocus with this type of adapter. You will need to manually focus the lens when using this type of setup.
Overall, an EF to EFS adapter can be a useful tool for those who want to use their lenses on both types of cameras.
Just keep in mind the limitations of this type of setup before making your purchase.
How to Use Efs Lens on Full Frame
If you’re a full-frame camera user, then you know that one of the benefits is the increased field of view that you get compared to APS-C cameras. But what if you want to use a more telephoto lens? The answer is an EF-S lens.
An EF-S lens is designed for APS-C cameras, and has a smaller image circle than an EF lens. This means that it can’t be used on full-frame cameras, but it also means that it can provide a greater field of view on APS-C cameras. When used on a full-frame camera, an EF-S lens will give you a cropped image.
The main benefit of using an EF-S lens on a full-frame camera is that you can get increased focal length without having to buy and carry around a larger and heavier telephoto lens. For example, if you’re using a 24mm EF-S lens on your full-frame camera, it’s equivalent to using a 38mm lens on an APS-C camera. If you wanted to get the same field of view with an EF lens, you would need to purchase and carry around a much longer and heavier 70-200mm telephoto Lens .
So, if you’re looking for increased focal length without the weight and expense of buying and carrying around a larger telephoto Lens , then consider using an EF_s Lens instead!
Will Ef-S Lens Fit Canon 5D
If you’re a Canon DSLR user with an EFS-mount lens, you may be wondering if you can use that lens on the new Canon 5D Mark IV. The answer is yes… but with a caveat. The EFS mount was introduced way back in 2003 with the original Canon 10D, and it’s been used on every subsequent Canon DSLR released since (with the exception of the 1-series cameras).
So, if you’ve got an old EF-S lens kicking around, it will physically fit onto the 5D Mark IV. However, there are a couple of things to keep in mind. First off, EF-S lenses only provide full coverage on APS-C sensor cameras like the 7D Mark II or 80D.
That means that if you try to use one of these lenses on a full frame camera like the 5D Mark IV, you’ll get vignetting in your images. Secondly, due to the crop factor of APS-C sensors, EF-S lenses have shorter focal lengths than their full frame counterparts. So, for example, an 18mm EF-S lens will produce images with roughly the same field of view as a 29mm lens on a full frame camera.
Keep these things in mind and you should be able to use your EF-S lenses without any problems on the new Canon 5D Mark IV!
Can You Use Ef-S Lenses on Eos R
If you’re a Canon shooter, you’re probably wondering if you can use your EF-S lenses on the new EOS R mirrorless camera. The answer is yes… with a caveat. You can use EF-S lenses on the EOS R, but only in crop mode.
This means that the sensor will only record the center portion of the image, and you’ll end up with a 4:3 aspect ratio instead of the full-frame 3:2 aspect ratio. So why would you want to do this? Well, it’s actually not a bad way to get started with the EOS R if you already have a bunch of EF-S lenses.
You can still use them and get great results, although you won’t be able to take advantage of the full capabilities of the camera. Once you’re ready to upgrade to full-frame lenses, then you can start taking advantage of all that the EOS R has to offer.
Canon Ef Lenses
There are a few different types of Canon EF lenses, each with their own unique benefits. Here’s a quick rundown of the most popular options:
Standard zoom lenses: These versatile all-purpose lenses cover a wide range of focal lengths, making them ideal for everything from landscapes to portraits.
Telephoto zoom lenses: These long-reaching lenses are perfect for sports, wildlife, and other applications where you need to get up close and personal without disturbing your subject.
Prime lenses: With their fixed focal length, prime lenses offer sharper images and faster shutter speeds than zoom lenses. They’re also typically smaller and lighter, making them a great option for travel photography.
Macro lenses: These specialized close-up lenses allow you to capture intricate details that would otherwise be invisible to the naked eye.
Canon 5D Mark Iv Lens Mount
The Canon 5D Mark IV is a high-end DSLR camera that was released in 2016. It features a full-frame sensor and can shoot 4K video. The camera is also compatible with a wide range of lenses, including EF and EF-S mount lenses.
In this blog post, we’ll take a closer look at the Canon 5D Mark IV’s lens mount and what it means for your photography.
The Canon 5D Mark IV has an EF lens mount, which is the same mount that is used on the company’s other DSLR cameras. This means that you can use any EF or EF-S lens with the 5D Mark IV.
If you’re using an older lens that was designed for film cameras, you may need an adapter in order to attach it to the 5D Mark IV. However, adapters can introduce vignetting and other issues, so it’s best to stick with lenses that were designed specifically for digital cameras.
The EF mount has a diameter of 54mm and a flange focal distance of 44mm.
This gives the Canon 5D Mark IV a fairly large image circle, which is important for full-frame sensors. The flange focal distance is also relatively short, which makes it easy to adapt lenses from other mounts (such as Nikon F or Micro Four Thirds) using readily available adapters.
Overall, the Canon 5D Mark IV’s lens mount is very versatile and allows you to use a wide variety of lenses with the camera body.
Whether you’re looking for wide-angle, telephoto, or anything in between, there’s likely an EF or EF-S lens that will suit your needs.
Efs Lens on Eos Rp
The EF-S lens mount is a derivative of the EF lens mount created for Canon DSLR cameras with APS-C sensors. It was released in 2003 along with the Canon EOS 300D. The main difference between an EF-S lens and an EF lens is that the EF-S lens has a smaller image circle, which is only large enough to cover the smaller sensor found on Canon DSLRs with an APS-C sensor.
This allows lenses designed specifically for the EF-S mount to be smaller and lighter than theirEF counterparts while still providing full coverage of the sensor.
Lenses designed for the EF-s mount will also work on cameras with full frame sensors, but there will be a vignetting effect since the image circle produced by these lenses is not large enough to cover the entire sensor. There are currently over 60 different types of lenses available in the EF-s lineup, ranging from ultra wide angle to telephoto zooms.
Many of these lenses are also available in versions for Canon’s other camera mounts, including the EF, RF, and FD mounts.
Ef-S Lens on Rf Mount
If you’re a Canon shooter, you’re probably familiar with the EF lens mount. But what if you want to use those same lenses on a different camera system? That’s where the EF-S lens mount comes in.
The EF-S lens mount is a derivative of the EF mount, and it was introduced by Canon in 2003. The main difference between the two mounts is that the EF-S mount has a shorter flange focal distance. This allows for smaller and lighter lenses to be used on Canon DSLRs that have an APS-C sized sensor.
Some of Canon’s most popular lenses are available in both EF and EF-S mounts, so you have plenty of options to choose from regardless of which camera body you’re using. And if you ever decide to switch systems, you can still use your existing Canon lenses with an adapter.
Conclusion
It is possible to use an EF lens with a 5D camera, but it is not recommended. The reason for this is that the image quality will not be as good as if you used a native EF lens. Additionally, there may be compatibility issues between the two types of lenses.
