p.1 #1 · p.1 #1 · whcih adapter for c/y eos mount to reach infinity on distagon 28mm


I once had a zeiss distagon 28mm f/2.8 and I'm going to buy it again (just liked the iq too much).

One problem I had with this lens was infinity focus. I had to use f/8 to achieve that.

I have 2 eos c/y adapters: from happypagehk and big-IS. Both acted the same.


I saw a tutorial on a distagon 25mm to adjust infinity focus on the lens it self but my guess the adapters are the problem.

Which adapters are "thinner", more realiable so the distagon 28mm f/2.8 can achieve infinity focus at f/2.8?

The Fotodiox Pro adapter should do it for you. OTOH, I prefer the Leitax mount kit, which is even better.

P.S. you're using a Canon camera, right?

Just flip the adapter over (lens mount side down) on sandpaper and give it a couple of goes, test, repeat.

I use a Canon 5D.
Leitax looks sturdy but also bit pricey. What I care about is the infinity focus. I can try to sandpaper one of the cheaper adapters but I think that is very difficult to do that evenly?

Go in a circular motion, there are a few threads of people doing this in the past. You may only need to shave off a tiny bit (.1mm), so go slow; better to do it once and get it right than to realize you went too far and need to order a new one.

Was the Distagon 28/2.8 the only Contax lens you have used with those adapters? I have a happypageHK adaper and all of my Contax lenses (28/2.8, 50/1.4 and 100/2.8) reach infinity on it.
