Can You Use RF Lenses On 5d Mark IV: [Answered]

RF lenses are an ultra-wide-angle lens type that is typically used for photography. They are designed to work with cameras that use different image sensors. So, can you use RF lenses on a 5D Mark IV?

No, You can not use RF lenses on the 5D Mark IV. For EF DSLR cameras, you must not install an R/F lens on an EF mount. This lens was designed specifically for the new mirrorless Canon line.

Today I would like to share some vital information about RF and EF lenses. So, let’s go!

Can You Use RF Lenses On 5d Mark IV?

No, you can’t use rf lenses on your 5d mark iv. You can not use the RF lenses where the EF mount is used in your DSLR. The distance between the back of the camera sensor and the lens element in RF lenses is also very short, only 20mm. It is 44mm on EOS DSLRs. An RF lens would fail to achieve focus with an EOS DSLR camera because the sensor is too far away.

You cannot use RF lenses on a 5D Mark IV for the same reason you can’t use EF mount lenses on a Canon Cinema EOS camera: the sensors in these two cameras are incompatible. The specifications of Canon digital cinema cameras, including the 5D Mark IV, employ EF mount sensors and the sensors in EOS digital cinema cameras, including the C700, are different.

Do EF Lenses Work On 5d Mark IV?

There are two types of Canon lenses: RF and EF. The first is a full-frame option, while the latter is a crop sensor lens. Lenses with an EF mount are compatible with full-frame and crop sensor bodies, while RF lenses will only work on an entire frame body. EF-S lenses are not compatible with the 5D Mark IV. When using RF lenses on the Canon 5D Mark IV camera, it is essential to consider.

These lenses are designed differently from the regular EF and EF-S lenses. They are not compatible in some rare cases. EF-compatible cameras will most favorably operate with EF-compatible lenses. Instead, these lenses use some form of electromagnetism, allowing them to focus and correct themselves when it comes to different distances. The accuracy is only achieved when your lens and your subject’s far away from your sensor match up at their typical focal lengths.

Canon R5 Vs 5d Mark IV Image Quality

If you look carefully at the image quality comparison between the 5D Mark IV and the Canon R5, you will notice that the 5D Mark IV focuses with a longer distance on its sensor. When using RF lenses, you will have to focus much further than they would on a full-frame camera.

The built-in rangefinder

If you own an EF mount lens, you can not use rf converters or rf wireless transmitters. For example, the Canon EF mount lens 50mm 1.4 USM is incompatible with an RF transmitter and vice versa.

IS

Finally, the type of IS system used will determine how well the lens would benefit your image quality. The varying types of IS systems are helpful in a multitude of situations. They can make your video recording or photography much easier because they help correct camera movement and deviation from the observed subject.

Image stabilization

This is a standard feature on all Canon cameras, with a low amount of vibration occurring during exposure. The 5D Mark IV does not have image stabilization, but most digital cameras nowadays have this technology built-in.

Internal focusing

That brings us to another essential aspect to consider when using rf lenses on the Canon 5D Mark IV camera. There are two types of RF lenses: RF and EF. The first is a full-frame option, while the latter is a crop sensor lens.

The type of image stabilization

As mentioned above, there are various types of image stabilizers. Generally speaking, the better your IS system is, its features will be more comprehensive.

Autofocus

This feature is available only with EF lenses and is not compatible with RF lenses.The type of aperture you choose to use will significantly affect the image quality produced by your lens because it can change based on its focal length.

RF Vs EF Lenses: The Differences

Canon RF lenses are compatible with full-frame (RF) cameras and crop sensor (EF) cameras. Image stabilization is present but not adjustable: the 5D Mark IV body will control how this technology works. Canon EF lenses can be used on full-frame and crop sensor Canon 5D Mark IV bodies but will only be active on a full-frame camera.

RF Vs EF Lenses – Which One Should I Choose?

The EF focus system makes this camera tick, while the RF system is designed to keep your camera steady during exposure. You can’t mix the two systems and expect them to work correctly. However, you can use an EF adapter to make an rf lens work on a Canon 5D Mark IV camera.

You will not be able to utilize the autofocus function, but it will still function when shooting in manual mode. Another important aspect worth mentioning is that your lenses need an internal focusing motor to work correctly on the new Canon digital camera.

The level of sharpness for the RF version is also considerably less than EF Sigma 50 mm f 1.4 lens, yet it’s still marginally less wide open. Keep in mind that the differences are there in the eyes if you are looking for them. But they tend to disappear compared with the differences between the RF and EF versions of the 70-200 or 24-70.

FAQs

Is Canon 5D Mark IV RF or EF?

All Canon 5D Mark IV cameras come with EF lenses. The RF lens design provides a larger frame for lenses, making them more compact and sharper than the EF variety.

Can you use an RF lens on a DSLR?

No, you do not use an RF lens on your DSLR. An RF lens by design has a focal distance comparable to that of an epicyclic cinema lens designed for broadcasting. Although EOS DSLR sensors are closely spaced, any RF lens’s focal distance is under 45mm.

What lens can I use with Canon 5D Mark IV?

You can use Canon EF 24-70mm F/2.8, Canon 100mm F/2.8 as a macro lens, Sigma 85mm F/1.4 as a portrait lens, Canon EF 24-105mm f/4 as the best zoom lens, and Canon 50mm F/1.4 as overall for your Canon 5D Mark IV.

Are RF lenses compatible with EOS cameras?

You can mount  EF, TS-E, and MP-E  Adapters to your EOS R camera body. You can also use the EF-S and EF-M lenses from our EF-M lens adapter series .  If you already own a Canon EOS R camera, you can also use these adapters.

Final Words

Canon 5D Mark IV cameras are the company’s best tool. Their high megapixel sensors are ideal for shooting landscapes and other photos, and their ergonomic design makes them a joy to use.

If you’re still confused about- can you use RF lenses on 5d mark iv or not, please scroll up and read the entire post carefully. However, not all lenses work great on this camera body, so you should stick to EF mount types.
