EF-EOS R Pro Auto Focus Lens Mount Adapter with Security Lock Compatible with Canon EF/EF-S Lens to Canon EOS R R5 R5C R6 RP C70 Red Komod Camera,Idea for Large Lens

The item works in every way. There are no questions about its performance. It works as it should. In fact, it works exactly like the Canon equivalent. The only issue is that it is not as easy to change lenses with this one. You need both hands, and it requires some muscle to change the lessons. It is not intuitive to use. I have had it for several months now, and I am never satisfied that I have attached the lens properly, and constantly have to double check that the lens is secure. It is not as easy to remove or attach a new lessons because of the way their locking mechanism works. The canon one is easy, straightforward, and secure. You can change the lens with one hand. If you ignore the above, the of the adaptor is great. It is better priced than the Canon one. I am still using it so if you can overcome issues with removing the lens and attaching one, then the it is a solid investment and offers great value for money. The materials are solid just like Canons. I cannot talk about longevity because I have not had it that long.

Fits well works very well with camera and ef lens .easy to use

Be careful how much u tighten it. Hard to get off. I don’t think anyone will like how that works

La costruzione è accurata, si fa una certa fatica per bloccare l'obiettivo, in compenso non ci sono giochi, speriamo che con l'uso si allenti un pochino il bloccaggio

Le système de fixation de l’objectif risque de l’abîmer si l’on serre trop, dommage car tout le reste vaut le coup

Ottimo rapporto qualità prezzo
