I have a variety of pre-set type lenses, most of them are for ExaktasJust received a Zeiss Jena Tessar 3.5/50 T in Exakta mount. The distance scale is in feet, but there is a meter scale with red digits on top of the focus ring. This was an export model for the US market made in 1954, and the last batch produced with this type of housing. It looks like it was the standard lens supplied with the Exakta VX export model. It needs lubrication, but that seems to be rather straightforward. These lenses are supposed to have aperture pre-set, but I cannot figure out how it works. Sometimes when I go past the minimum aperture mark there is a click, but it's not consistent. Has anyone used pre-set on this lens?

Congratulations! I look forward to seeing some images!Just received today a leica sl2s. Battery is currently charging.
Here is an Exakta mount preset lens where the button must be pressed and the ring turned to specify the minimum aperture to be used (here f/8). The lens is currently at f/4.5. When turning the ring, it will stop at f/8.
This doesn’t directly answer the question above, but it does give an idea about how most of these preset lenses function.

Congratulations! I bought mine exactly one year ago and love using it with M-mount glass, and recently with Canon L glass. Cheers, OtLJust received today a leica sl2s. Battery is currently charging.
Thanks Pál_K! There is no button on my lens and it has only one ring, so it is most likely not a pre-set type lens. What lens is yours, I have not seen that one before?
It is not possible to either push or pull the aperture ring. I've carefully re-read the German page I use, and it seems that it is the model following this one that has pre-set. The page I'm using has a lot of detailed info on various lenses for Exa/Exakta, you can find it here: Photo but More - by Horst NeuhausIt is a Rodenstock Rotelar 180/4.5 which lives among my Exaktas and other lenses:

If you try gently, does the aperture ring on your lens pull out or push in?
You may wish to look at these pages just as a source of general information about Exakta lenses:
