Kevin:
Since 3DS lens numbers mimic the optics of a 35mm camera lens, and a 50mm
lens is considered "normal" in the photography world, that would be your
best bet. The target distance actually has nothing to do with the lens
size, it's a vector, nothing more.
There is really no way to mimic the 180 degree peripheral vision you
mentioned in optics without some major distortion in the lens itself.
(fisheye effects) Just set your lens at 50mm and get REAL close to your
monitor! <g>
