Hi Dwight-- The focal length is 1" (25mm); the f/no is 138.
To use the wheelie, take a light meter reading. I usually meter for f/64, set the indicated shutter speed opposite the f/64 aperture on the wheelie, then you can read the shutter speed for f/138. Should be about 2-3 stops more exposure than f/64. Then figure in reciprocity, if necessary. Hope this helps-- Jan TSHACK wrote: > OK, I'm just getting back into pinhole, pulled out my Zero 2000 camera > (never used) and seem to have misplaced any instructions that might have > come with it. > > What I need to know is the f/stop of the thing.
