Fotodiox Lens Mount Adapter, Contax Yashica c/y (cy) Lens to Canon EOS Camera Adapter, for Canon EOS 1d,1ds,Mark II, III, IV, 5D, Mark II, 7D, 10D, 20D, 30D, 40D, 50D, 60D, Digital Rebel xt, xti, xs, xsi, t1i, t2i, 300D, 350D, 400D, 450D, 500D, 550D, 1000D

I almost ruined a thousand pound lens due to this adapter. It’s not designed for use on all C/Y lenses and this got stuck on one of my Contax Zeiss lenses. The metal pin on the lens got caught on the C/Y side where the channel carved for it wasn’t deep enough. Essentially I had to cut this thing off. Only purchase of the seller agrees to cover the cost of repair should this thing damage your kit.Be Warned!

Good

The worst ever product & customer support I've ever experienced.I bought 4 lens mount from this seller as I read a couple of positive review on the internet.1. M42 to EOS & M42 to Fuji adapterAltough they are advertised to support infinity focus, they do not in fact.When I focus to infinity everything is out of focus.I had to reverse focus ring to make it focused.But I did not take this as a serious problem as it seems too minor issue2. C/Y to EOS & C/Y to Fuji adapterThey had much worse problem.C/Y to EOS did not work properly with Canon 5D Mark II.With focused to infinity, the mirror was stuck open after sutter release.I tried Canon 7D as well sometimes had no issue sometimes had same issueI also found light leak using C/Y to Fuji adapter. The light came through where lens release button located.So I contacted the seller and explained these issues.They told me to return the item and I sent back the item.No response for long time. I contacted again but they said the item not delivered yet.But I knew the item already delivered as I had tracking number.Contacted again and they said the item was under inspection this time.Another 10 days or so replacement for C/Y to EOS was delivered without any notice.However the replacement had same issue and I asked for refund for C/Y to Fuji adapter including return postageHere is their reply."Hello We did check the adapter when it arrived back here, and found that it was not a flawed item. That is why the refund department did not refund you shipping in either direction. As a courtesy to you I will refund the shipping to the point of what we charged you to ship, and use that amount to refund a portion of the return shipping."They are GENEROUS enough to give me a courtesy of £3.48 in fact return postage costed me £18.55 as they are in USThis is summary of what I experienced with this seller so please avoid this seller.

Excellent metal finish, does what it says it does, hassle-free, sturdy even if I noticed a bit of loosness with the yashica 28mm.
