Exidalens on retina.jpg

I just found this file

on my computer, but I cannot trace back how it came into my possession.

What is that?

Is this a normal Retina lens where the front bezel has been exchanged, or is it actually possible to use M42 lenses on a Retina Reflex? If yes, by means of an adapter, or how? 😕

It's probably DKL mount. I saw one of those for sale on eBay in the past couple of weeks. Here's a little more info, where the author states that it is "Retina" mount:

Edit: the flange focal distance of m42 is shorter than DKL. DKL is actually longer than the Nikon F mount, making it one of the few 35mm mounts that can be adapted to Nikon F and still focus to infinity without supplemental glass.

Mich, you're right, on a Retina Reflex one would expect a DKL-mount lens.

But here it's not the Schneider-Kreuznach *Retina*-Curtagon 28mm f4, it's a Schneider-Kreuznach *Edixa*-Curtagon 1:4/28.

And you're right, one can adapt DKL-mount lenses quite comfortably, there are adapters, e.g. for Nikon-mount or M42-mount cameras, ready available.

But here we seem to have the exact opposite: an Edixa-lens on a DKL-mount camera.

But I guess the thing is much easier explained: I didn't recall until now (Edixa = *always* M42, I was erroneously inclined to suppose), there was an Edixa camera having DKL-mount:

So there's very probably no exchanged front bezel, and especially no adaptation M42-DKL-mount -- the latter would be mechanically quite the effort I guess.

Well, that would explain why it's called Edixa-Curtagon instead of Retina-Curtagon. I didn't know there was an Edixa DKL mount camera, so that explains my mistake.

I just bought a DKL to Nikon F adapter a couple of weeks ago, and it makes for the smallest pancake 50mm f/2.8 for Nikon that I've seen. The lens plus adapter are just a smidgeon bigger than the Zenit Industar 50-2. Plus the lens looks stunning.

Mich, apologies, it was mainly my mistake 😱

😀 having a similar adapter, I use my Voigtländer Color-Skoparet (Vitessa T standard lens) or the humble Steinheil München Culminar (Braun Super Colorette standard lens) on several SLRs. I even prefer them over the much more recent (and probably muuuuch costlier) C/Y mount version of the Carl Zeiss (West Germany) pancake Tessar, since they have these nifty focusing levers -- certainly not as noble as the Leica focusing levers, but still very good 🙂
