I recently bought a nice little repro lens, the Schneider-Kreuznach G-Claron 240/11 WA. The Schneider-Kreuznach archive contains some more information on the G-Claron 240
So without a real plan, only a rough idea I went ahead and bought some materials to build myself a little lensboard. With a little wood, some glue and a few nails I quickly threw together that lensboard. Add some felt to make it completely light-tight and you're done.
There are a few slight problems though:
- Focusing on infinity seems very difficult since it's just a matter of a Millimeter wether that house or the horizon is in focus
- Fully open at f11 it's a little dark to work with. Since I can't manage to remove the front element I can't (try to non-destructively) modify the aperture to open up more which sucks quite a bit
The rail of my little 4x5 sinar f is too short to focus on a close subject like a person's head, which is what I intended to do with this lens in the first place.Update: Just turning the rear stand by 180° would give me the leeway needed for now, for truly format-filling portraits I'd probably have to extend the rail.
However, it's great fun to take some lamp, place it about 10cm from the lens and project the glowing filament onto a wall 5m away. I did a pretty cool 24x30cm direct print.
Here are the progress pictures:
