Hello,
I mounted a Super Angulon 47mm/8 on my Crown Graphic for the first time and even shot one roll of film. This is really superb combination!
Now I am at the stage of making my work with this setup more comfortable. Following are the problems I would like to resolve:
extremely hard to frame the shots using the ground glass back not only because the lens does not have separate focusing mode (a lever for instant diaphragm opening), thus requiring constant diaphragm switching back and force, but also because even at f8 the image is so dark at the corners, that one barely sees anything even in the bright light.
constant back-switching (from ground glass back to film roll) usually causes for focus and framing loss.
SA47 requires the front lens-standard to be locked on the part of the rails before the drop-bed. I noticed that on my Crown this part of the rails is somewhat more loose then the ones residing on the drop-bed itself, which sometimes causes the standard to be stuck while focusing (because the rails start to rise a bit and the standard leans a bit forward or backward). Does anyone also have a problem like this, or this is only the problem with my camera? If this is my problem, how do I tighten these rails?
I think the problems 1 and 2 can be solved by attaching some kind of wide angle viewfinder to the camera. Then I will not have to put the ground glass back at all (focusing very hard on this lens, so I will just prefocus it to hyperfocal distance). Does anyone know which viewfinder shall I put? I shoot with 6x7 back.
Does anyone know what is the hyperfocal distance for this lens?
If anyone knows any other useful information on how to comfortably use this Crown+SA47 combination, your help will be very appreciated.
Thanks
Denis
