Hi,
I'm confused because I got an Imagon 250mm and I've ordered a Chaminix H-1 (not shipped yet).
The previous owner of the Imagon told me that he was forced to buy an extension for his Sinar F2 - otherwise he couldn't get in focus.

My intention was to use the H-1 with the Imagon for portaits (2,5m - 3m distance to the subject). I've calculated that the focus plane will be at 273mm.
Is that correct?

At the H-1 the bellows can be extended up to 340mm. So I see no reason why it shouldn't work. Maybe the standard rail length of the Sinar F2 is too short?
