Hi all,
I am making large format camera prototypes since a few months. My next one will be a handheld 8x10 wide angle camera. I will use a Schneider 121mm, a 8x10 back, and a lot of tape, black foamcore boards, and some home made aluminum parts.
This will be a focus free camera, I intend to focus the lens at 30.4 feet, which is the hyperfocal distance at the maximum aperture of f8, this will give me the maximum depth of field at all apertures. At f64, it will focus from 3.38' to infinity.
My question here is, how can I make sure that the lens will be focussed at 30.4 feet... Is there a way to calculate the exact distance between the ground glass and the lens flange when focussed at exactly 30.4 feet ?
thanks
Eric
