The goods arrived on time, as usual from K&F Concept. As far as I can tell as an ambitious hobby photographer, the product does what it promises. In any case, it meets my personal expectations. Its durability remains to be seen. However, based on my previous experience with other products from the company, I assume that this autofocus adapter will also serve for a long time. The feel and appearance are of high quality in my opinion.

Seems very solid, autofocus works quickly and reliably on my XT30ii with Sigma 18-35. I can recommend it - especially for the price.

The adapter is in the same price range as the original. The difference is too big for that:
Positive:
- it works, the adapter fits the camera and lens.
Negative:
- no sealing lip on the camera
- fewer and smaller screws hold the thing together than the original
- there is no USB port (why not, but then just don't write it in the description!)
- metal housing... yes, but internally screwed together somehow differently.
- contact surface for lenses too small, the sealing lip of the lens reaches into nothing and is therefore ineffective.
- there is no "pro" printed on it ;) well... actually correct given the features, but still doesn't match the photo.
Neutral:
- why do you have to put a tripod adapter on it?!? I either use it on the camera or on the lens. You can remove it, you just have two holes.
Clearly: definitely not a purchase recommendation for EF L lenses! The thing is going back immediately.

The ring that the original manufacturer doesn't have in stock, very good quality replacement product
Nickel, allowed me to use my Canon EOS lenses with an R-type device

K&F has created a very high quality lens, the materials are very good and resistant. I have tested it by mounting a Sigma 18-35 on a Canon EOS R series and it works wonderfully.

I have had the opportunity to try this adapter for a month now and I think it is really excellent, it has never given any connection problems and the autofocus with all my EF lenses is perfect, also the construction is excellent and it fits perfectly with my mirrorless. I think it is the best alternative to the official Canon adapter at a much lower price.

Betrayed by the age and weight of the bodies and lenses, I bought a lighter and more modern Sony body. The Canon 28-105 USM was a faithful companion, so I can keep it thanks to this adaptor ring.

I bought this adapter to mount it on a Sony case (the 6700) and use the Tokina lens (ATX I) in manual mode.
