Contax Yashica Lenses to Canon EF Lens Mount Adapter K&F Concept M14131 Lens Adapter
4
I never used this adapter with an auto lens. Works well with my Yashica 50mm and 135mm manual lens. Doesn't work as well with my Promaster 70-300mm the adapter is nice and tight on the Canon 2000D but the lens is allowed to turn and can unlock itself, this could just be a lens problem, I'm not sure.

It's a ok quality C/Y to Canon EF, mounts tight to my Canon DSLR body only, had an issue and contacted K&F received a solution same day, 5 STARS for support.No adapter is as good as the original lense (YOU MUST UNDERSTAND THAT) but for a low cost of $28 kinda does the job, just be carful on the lense side not as secure as a C/Y camera body.

Out of the SIX adapters i bought, this is the ONLY adapter that allows my Contax Zeiss glass to work on my Elan film cameras. I have two C/Y lenses (35-70 3.4*T and 80-200 f/4) that I used on my Contax RX and Sony A7r2, but wanted a film camera that was A) lighter and B) would work with my Zeiss ZE 21mm.This adapter WILL NOT clear an Elan IIE mirror on any focal length on these two lenses. The Elan 7 and Elan 7E it WILL work, except at infinity. So you have to stop just short of infinity, but that is a compromise I was willing to deal with. Otherwise a Leitax mount swap is the only way to get a C/Y mount lens to work; and even then, some C/Y lenses won't work with certain EOS cameras, digital or film.

I have had a plethora of adapters for both EF and E-mount, but this is by far the one that has had the least play. Feels more or less as sturdy as a Leitax conversion.

Using this to mount an older Tokina 500mm mirror lens with Contax/Yashica mount on my Canon 60D, the adapter is very thin and works great. Focusing to infinity works great as there is plenty of focus range to play with.

I think that this is an amazing lens mount. It was very useful and it fit perfectly with my canon 550D. Fantastic product.

This is well manufactured, with infinity being achievable for all C/Y lenses. Both MM and AE mounts are accommodated and most lenses seat firmly with no unwanted movement when being focused or, when required, zoomed. The simple design of the small lug that secures the lens makes attachment and removal a simple process - how durable this is only time will tell. As for those lenses that did not seat securely, it was the lens mount that was the issue (worn by the passage of time and regular removal and re-attachment) and not the fault of the adapter.I have more expensive adapters but to be frank, the quality of the K&F unit is more than adequate and I have to question whether spending £30-80 more makes any real difference - I can heartily recommend this product.

Perfect and, unlike some I've tried, can reach infinity focus with Yashica ML lenses.

Using this to adapt a Zeiss planar 50.7 on a lens turbo II to a NEX 6.There is no play between the adapter and the camera mount which is a issue on my chrome-plated brass copper Contax adapter ring. Although this is made of lighter material, (aluminum maybe?) this adapter still has a solid build and it works better, I cannot said anything durability for this particular item but I have half a dozen of various adapter rings before, none of them have had any issue. I would recommend this to people who don't need AF confirm function.
