There are loads of good large format lenses around in barrel that would be
great to use with the 3x4 SG once you have a back solution worked
out. Having a focal plane shutter opens up a whole new world of possibilities.
Good quality enlarging lens most certainly do have the resolving power of
camera lenses. They tend to be small apertures though - if you are not
using the ground glass this may not be a problem, however to work well at
infinity they would need to well stopped down. Maybe your friend was
thinking that at the apertures you would need to use then diffraction would
come into play for infinity shots.....
Finding bargain large format lenses in barrel should be relatively easy - I
have a box full that I'm waiting for an opportunity to try out :-)
If you can sort out the back solution to your satisfaction in one of the
ways that Les suggested then you'll have a very flexible camera to use.
