RF and EF lens compatibility with EOS R6 and EOS 2000D

Aceson — Tue, 24 Sep 2024 14:16:26 GMT

Hello, I'm a high school student; I have started doing sports photography as a side gig. I have some questions; first off, I've been thinking about buying a used Canon R6. I am confused about whether my current EF lenses will work with the R6 or if I will only have to use RF lenses and buy an adapter. Also, I have a Canon EOS 2000D right now; I have been using it for about a year now and absolutely love it. I have started taking it more seriously and have thought about buying a used R6, which is in my price range.

Any help at all will really help me out.

Thanks!

You can use EF and EF-S lenses on an R camera with the Canon adapter. Not that if you use an EF-S lens, it will crop the image on the R6 to the APS-C sized frame.

Hi and welcome

What lenses do you have now?

As my colleague indicated, while you can use EF lenses on an R6 via the EF-RF adapter, using EF-S lenses have the issue that while they physically commect, they will project onto only part of the FF sensor, reducing the sensor ny a factor of 2.56. Thus your 20MP R6 sensor is reduced to about 7.

Hello and thank you for the help. I have a 70-300mm 4.6 right now, this is what I use for sports photos.

Thanks for your response. Can I assume you mean a variant of the Canon EF 70-300 f/4-5.6 IS USM? You can use any version of that lens on the EOS R6 via a Canon EF-RF adapter and use the whole sensor area to delivery the full 20MP image potential.

Using a crop-sensor camera such as the EOS 2000D will have an impact on how it captures the image projected by the lens. Essentially, the crop sensor has a 'magnifying effect' on the resultant images, making it seem like you are using a longer focal length lens than is actually the case - specifically, for your lens the results will seem like you are using a 112-480mm lens. This is not obvious when you are sticking to one type of sensor, but when you use that same lens on the Full-Frame R6, then you will seem to get a lot less magnification - essentially, it is delivering the Field of View of its native 70-300 focal range. If you wanted to get the same Field of View with the R6, then you would use something like the an RF 100-500 lens.

Canon EF 70-300 f/4-5.6 IS USM?

You do mean 70-300mm and not 75-300mm? Is your lens white or black? If it is the black one I am not sure I would spend the cost of the adapter to use it on a new R series body. And if it is the 75-300mm I absolutely would not but if it is the white one you are good to go.
