Pinhole Resource and other places sell EOS (et al) pinhole bodycaps ready
made for about $40-50 dollars or so if you want to go that route. Or if you
want to make your own, it's a 50mm focal length unless you want to get
creative and extend your focal length by putting the pinhole on some
extension tubes or if you wanted to reduce you focal length by some method.
I can't speak to the built-in exposure but you could try aperture priority
if it can be set to f/180 (which I believe is the rounded "ideal" f/stop for
a 50mm focal length)
I bought the pinhole body cap from Eric Renner and have been very happy
with it. My only complain is maybe it's too perfect. I'm ready to start my
own experimenting to try and build a small ultra-wide angle 20mm focal
length 35mm film format pinhole. If anyone knows of a ready-made small 35mm
wide-angle I would appreciate the info. Thanks, Thom
