It allows you to use CANON FD mount lenses and macro accessories on Canon EOS cameras. Used on Canon 80d with only small issue of flare but no a big issue and varies on lenses.

Bought this cos I have some old fd lenses and a new 80d camera I would like to say at this time it feels a quality bit of kit. Now I have had some issues with it regarding a flare in the centre of the image, it looks the same as the dampness you get on the inner elements with big temp changes That circular mist. But it is a flare and I can work with it, the old lenses have full focal function to infinity and the manual side is great to play with :) how many pics can you fit on 32 gigs. I was on the verge of sending it back so glad I gave it a second chance. Hope my comments are useful.

The product is of excellent quality. It did fit p[erfectly on my new Canon 5D mark lll and my old original Canon Japan lens 100 - 300mm I actually have tested the new adapter I used a tripod and the result is amazing ! Soooo Happy

Good quality metal build, however it does not allow infinity focus on my Canon FD 200mm F2.8. Although it might be my lens as its a repair. Glass is alright. Very soft images when wide aperture. dont really know if it was worth it. does add a spice of creativity to your lens arsenal.

The person that owns the local camera store, told me this item didn't exist, there was not a converter that would take my lens from an AE to the new canon EOS. That even if there was the auto settings would not work and would have to be set on manual. He wanted me to bring it in when I received. He was also impressed and was glad to know there was an adapter and would tell his clients. However, in all fairness, I have only taken two pictures with this but the auto settings on the camera seem to also work.
