Set Contains: Box contents: Bayonet adapter EF-EOS R; camera housing cap R-F-3; rear lens cap RF; case; user manual (English language not guaranteed) Review: Get it!!! - I just bought a brand new eos r50 upgraded from a rebel t7. While I was excited, you can’t help but think about all the money you invested in the other camera. It wasn’t too long ago that I bought a very nice 75mm to 300 Ef lens. Well this fixes just that problem you’re able to use all your older lenses and buy ef ones at a cheaper price in general. You can get a converter for cheaper but I recommend just splurging and getting this one it was made by canon so ofc it’s gonna work the best. The auto focus works better than it did on my actual mirrored camera, it fits perfect, and I got it used like new and it came in perfect condition. Highly recommend to someone who just upgraded from a mirrored camera!!!
