Works a treat
Hello...i've had this adapter for a while now and it works a treat with my EF lenses, primes and zoomy ones. Image quality is spot on Theres no wobble and everything attaches solidly. As far as i can say its weather sealed, was out in some torrential rain in the North East and there were no misfunctions. To those who say it makes the lens stick out more (of course it does its an adapter after all) but not in any way thats going to effect photographs or moving about, no way. Its saved me sooo much money not having to sell my existing EF lenses to buy replacements for my RF camera. Good Stuff....Bye.

Great money-saver.
Excellent and money-saving piece of kit that adds only about 1.5cms to the overall length of the camera. Great quality images as well. Highly recommended.

Simple and effective coupler at a very reasonable price (by Canon standards). Rapid service.

Perfect fit
I only bought my new Canon EOS camera once I found this adapter.My previous DSLR lenses added up to a lot of money and I wasn't going to lose that by selling them & replacing them when I upgraded to mirrorless.The adapter fitted onto the EOS in seconds, and the DSLR lenses fitted perfectly with the adapter.Adding it to the EOS is something most people wouldn't notice, except fellow photographers who notice every detail of every camera. So, in terms of how it looks ? Just right in my opinion. There's no distraction with how the camera looks.

All seems well.
Tried other non canon versions just to save money but they annoyingly lasted a short time. So decided to buy the correct item. Fits perfectly well and seems ok so far.

Works as expected
Given manufactured by canon - it works. Thats it.

A must if moving from EF to RF
Absolutely essential if you're moving from EF to RF and want to keep using your existing glass. The fit is flawless with no wobble or play and autofocus works just as fast and accurately as native RF lenses. It feels solid and well built like it came straight from the factory with the camera. A seamless transition that makes the upgrade to mirrorless so much easier.
