Hi, could anybody say how long is the distance between the film plane and the lens plane for this two lenses:
- Schneider Digitar 35mm
- rodenstock Grandagon N 35mm

The reason is: I want to know if I could use one of these lenses on my Technikardan.
Thank you.

On a TK 45 the 35mm Apo Grandagon uses the 001035 lens board which has a 21mm deep recess. Linhof does not list a board for the Digitar on the TK. But that Digitar probably has a much small circle of illumination then the Apo Grandagon. Why aren't you comparing the Schneider to the 35mm Apo Sironar Digital or the 35mm HR Digaron-S or the 32mm HR Digaron-W lenses. Although none of them cover 45 either.

If it helps you the 35mm Digitar uses the 001015 board on the Techno (12mm recess) while the 35mm Apo Grandagon uses the 001047 board (6mm recess) on the Techno.

Hi bob,
Thank you for your info.
I use a TK 23 with a digi back. The small circle is no problem for me.

But I think I will have a problem to sharp a digitar 35mm on the TK23 at infinity. I could use the recessed 21mm board..as you said..

Thank you.
