Canon Ef Mount Zoom Lens

[Yes] I use the Vello Canon EF/EF-S mount to use old Canon EF zoom lens on my Olympus Pen micro 4/3 cameras. It serves that purpose well. A caveat, probably already known to most, is that auto-focus lenes will work only in the manual mode.

[5 x 3.5 x 0.1"] Fits well on a canon EF-M 18-150mm.  Prevents the lens zoom from pulling out when the camera is taken out of the bag!

[Connector] This adapter only works on the Canon EF-S 18-135 USM lens, which is the newest of 3 versions. (I think this is an under-rated lens. It has a great zoom range, very good IS, its quiet, and low priced. While not perfectly sharp, it is close to the 24-105 and sharp enough for video. I use it mostly on my C 100ii.) If you like this lens, you will love this zoomer. It is well designed and built, and starts and stops smoothly. There is a little bit of noise at the fastest zoom speed, but not enough that my external mike will pick it up. As a bonus, it prevents gravity zoom. A good value at the current price.

[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.

[Sony E] Picked this up as what I hoped to be the best of the budget EF to E mount lens adapters. So far I've tested it with a handful of lenses and have seen no issues with any of the native Canon lenses I've tried: 24-70mm f/2.8L works great for AF, aperture, and Sony IBIS, as does 16-35mm f/2.8L III. Adapted lenses are more of a lottery - Zeiss Planar 50mm f/1.4 T* on a C/Y mount is great with Focus peaking on the A7RIII, however a Pentax Super Takumar 135mm f/2.5 causes the Sony to frreak out and flash the screen at random when displaying live view (menus display fine. The same adapted lens works perfectly on a Canon 5DSR. So, for the money I'd say it's good. Native EF lenses seem fine. More than 50% of my adapted lenses seem fine, but there are a few hiccups which are probably par for the course at this price.

[0.15 lb] I bought an Canon EF mount adapter for my Nikon lens so that I could use it on my Canon C100 and 60D or video. My old adapter was made by Bower and it had a lot of play which I hated. When I saw the Red Rock Micro adapter I though... I'll give it a shot since they make some great gear. I wasn't disappointed. There are 4 very small allen head screws that come with the adapter to lock it onto the lens. The micro allen wrench also comes with it. You snug then down and are good to go. No sloppy play! I plan to look for more Nikkor lenses and use these adapters. Get one!
