I should mention that the Viso III, with the 400/6.8 on something 
like the M4 or later is actually outstanding. Since the Visoflex did 
not have to deal with wideangle lenses, the optical system is 
actually optimized for longer focal lengths, and the viewing and 
focussing is really good. I used this combo for a number of years, 
and it works very well. I now use the 400/6.8 on a Canon 5DII, Viso 
III on M6, 7 & 8 and on the Panasonic G1 and overall, it still works 
best on the Visoflex but the other systems also make decent use of 
the lens.

For macro work the focal lengths might not be that long, but because 
of the extension the actual distance of the exit pupil from the film 
plane is also quite long, so the optics also work well with that. For 
this, actually, the Panasonic is best because of the auto brightening 
of the screen, the magnification when manually focussing and the 2x 
crop. The Aristophot never had it so good.
