I purchased this adapter along with the EOS M camera kit to use with my EF and EF-S lenses. After less than a week, I have been able to try out with the EF 50mm F1.4, EF 70-300mm L, EF-S 17-85mm, and EF-S 60mm lenses. The adapter fits perfectly. Same form and fit as the Canon extenders I have. The EOS M is of course made very tiny with any large EF lens. It creates a sort of 'pocket Rebel'. Of course, once you mate with the larger lens, this is no longer going to fit in anything less than a massive coat pocket. The combination of camera, adapter, and lens seems comfortable after brief handling. The EF 50mm was a very comfortable combination, the adapter does not add a very large amount to the overall combination. The upside to this adapter is if you already have a variety of EF and/or EF-S lenses. The image quality of the JPEGs, right out of the camera ranged from expected to stunning (the latter results obtainable with off camera studio flash strobe and soft box). The adapter was immediately a huge part of the EOS M camera purchase. I highly recommend it if you have other lenses. Again, the results I got with the EF-S 60mm macro (and studio lighting) were stunning. It transformed the camera from curiosity to studio prime. No problem using manual mode and Pocket Wizard. Include this adapter in your purchase and you won't be looking back.

WARNING! 50mm EF is not 50mm WHEN used on aps-c camera like T5i. Using this lens on my T5i resulted in photos being shoot equal to 80mm lens. GOOD- you get a 80mm 1.8 fixed lens for under $150. BAD - you don't get the advertise 50mm.

this is my second EF 50mm lens. My first one is has the plastic mount. This one is much quieter and auto focus faster

Purchased this for my Canon EOS camera so that I can use the Canon 50mm EF lens. Easy to use and no loss in function. I recommend for anyone who wants to use an EF lens with an EOS.

The Canon EF 50mm is a must for anyone who has an Entry Level DSLR camera such as the Rebel T7. The kit lens is fine, but this is a necessity for creating professional looking photos.This lens opens up a whole new world to the new or amateur photographer. I would recommend this lens all day long.

As Described. Fits perfectly on my Canon EF 50mm f/1.8 STM Lens with proper lock feature no wobble at all, Plastic made but solid build quality. In Matte black colour.

Exactly what I needed to use the Canon EF 50mm lens with my Canon EOS M50!

Canon did great work with this Canon EF 50mm lens! The picture quality is great and crystal clear! They've made it so easy to capture beautiful and creative shots with the range of aperture settings. I am thrilled with this little gem's capabilities! Highly recommended!
