I bought a RF 100-400 lens for my EF rebel ti7. Is there any way I can make it work? I don’t want to return it? Thank you

Hi Patti,
Thanks for your question about fitting a Canon RF 100-400mm lens on your Canon t7i. Canon has sure made it confusing when it comes to their different camera mounts and compatibility with their different lenses.

RF Lens/Camera Compatibility

While all of the EF and EF-S lenses can be used with Canon mirrorless M and mirrorless R cameras along with an adapter, the opposite is not true.

There are no adapters that will make an RF lens, like the RF 100-400, fit on a Canon DSLR, like the Rebel t7i. It has to do with the flange different spaces between the mounting flange and the camera sensors. To understand more on this see the post on Canon Lens Compatibility.



Canon Rebel t7i Lens Compatibility

The Canon t7i is compatible with EF and EF-S lenses. That's a good thing because there are so many of them, both used and new, available for you to choose from. That includes one of the EF 100-400mm lenses- I love mine and I use it on my 90D which has the same size sensor as your t7i. You got a lot of magnification with that combination.

See the advertisement for KEH on this page for used EF and EF-S lenses excellent condition.

Good Luck,
Bruce

RF lenses on DSLR
by: Stephen BP

I find it most annoying that I can’t use my RF 100-500 Len’s on my 5D iv.
I do have an adaptor to use all my existing lenses on my R5
