My collapsible Elmar 50/3.5 can't be fully collapsed. Theoretically the distance of the lens to the shutter/sensor doesn't change, but the shutter assembly as well as some other internals are in the way. On a NEX/A6000 you'll hit a baffle without too much damage, but on an A7 series you might touch the actual shutter and do real damage.Hello
I am new to SONY A7 cameras and fascinated by using old lenses on that camera .
I have a question here . Can I use a collapsible LEICA 50mm (Elmarit , Summarit or Summicron etc.) with an M39 adapter on a SONY A7 camera ? Does the collapsed lens collide with the sensor ?
Looking very much forward for your answers and thank you in advance .

Yes, it does!Does the collapsed lens collide with the sensor ?

I think it is left to the appreciation of the poster. But in any case : orphaned legacy glas that can't be mounted on digital bodies without an adapter. Plus older lenses from Canon (FD lenses), Nikon (Ais etc.), Olympus (Pen F or OM lenses) etc.. that were designed for film SLRs or range finders.A question to all posters in this thread .
How old must a lens be to participate in "old lens" contest ? :banghead:
I have received the KONICA HEXANON 2.4/50mm collapsible lens . Its like new . A wonderful lens .Vivek's post made me do another check and he's right, I probably mixed it up with the collapsing Voigtlander 40/2.8 Heliar, which is perfectly fine (fully collapsed it doesn't touch anything inside) . The Leica M39 Elmar 50/3.5 cannot be fully collapsed or it will start touching some internals. I'll amend my post above accordingly.
What he means with bicycle tube is that you can put a small rubber ring, cut from a bicycle inner tire tube, around the collapsing barrel of the lens and prevent the lens going in too far. That way you can collapse it partly/safely and make it physically impossible to push it in too deep.
