Hi,
does anyone know the exact distance of the filmplane to the external frame of a 4x5 film holder? I do not have one handy at present, so I can't check myself. I've noticed different distances of my sinar and Linhof camera backs, regarding the gg and the frame. (3.7mm / 4.2mm)
Obviously sounds little, only (!) 0.5mm, but when shooting wide open as I do, it matters.
Is there some technician out there (with a precision depth meter), who knows what the 'official' distance is supposed to be?
(I'm using simple gg, no fresnels or brightscreens).
Thanks,
Sidney
