Canon Ef Mount Mirrorless Camera

[0.03 lb] I have an old camera (RED One) with an aftermarket mount (Birger EF) and many Canon body caps are kinda loose on it. With this one, it locks into place and I have to press the lens release to get it off, which makes my looseness problem moot. Mine came missing the Blackmagic Design logo and is totally blank unlike the picture... not sure if that's normal, but that's all the better for my use.

[Yes] It allowed me to purchase a entry level Canon mirrorless and use my EF lens. Saving me a lot of money. Thank you Canon!!!!

[0.44 lb] I love this adapter that lets me use all my old EF glass on my newer canon mirrorless. Control ring adds so much versatility and helps me get to the shots I want so much faster!

[Full-Frame] I bought this lens as I had just gotten a new mirrorless camera. I had the 50mm EF lens and this RF works just as well. It is smaller but has the same capabilities. Would recommend to anyone who has an RF mount camera and is on a budget.

[4.3 x 4 x 1.4"] This adapter works to mount EF glass on EOS M bodies. Provides all functionality that Canon adapter does but costs less.

[Nikon F] It's distinctly heavier than others (Canon branded EF mount) that I own. It's also machined to tighter tolerances that yield zero free play in the lens mount. I'm using it paired to an RF 85mm f2 to yield right at 1:1 magnification

[360°] I was nervous about this produce before buying, due to the nature of adapting Canon EF lens mounts - but it is easy to install and the back focus was spot on. It comes with the correct (blue) shim already on the PL mount. I have only used this with Canon Sumire primes, so I can only speak to back focus being correct with no adjustments for this lens and it is Canon. The mount is super solid. Much better than the screw on Sony E mount to PL adapters I used with my FS7. Took 15 mins to swap mounts. Having EF and PL options takes away my stressing about cine lens options with this cam. I know I can get whatever lens I need, from any rental source for a shoot.

[0.045 lb] I purchased the Canon Mount Adapter EF-EOS R so I would be able to use my older 100-400 EOS lens with my new Canon R5 Mark II. Once it was attached I didn't even notice it was there. There was zero play or movement between the adapter and the lens or camera body. The adapter worked flawlessly while taking thousands of pictures in the Galápagos Islands, without issue.

Perfect lens swapper. I have one for Canon EF mount, micro 4/3 and now for the Canon RF mount. On a hike one can bring an extra lens without having to carry a bag. Easy to swap one lens with another without risks of dropping one. The lens his locked in place nicely.

[FUJIFILM X] Use on my old Nikkor lens to mount on EF cameras (Canon 5D, BMPCC 6K, Z Cam E2-F6). Holds the lens tightly, no wiggle, and feels secure.
