I've had some medium format cameras (Mamiya, Rollei, Fuji, etc.) but never a 4x5. The print quality has to be stunning! Do you have any scanned P-car images in 4x5 you can post? I will confess to buying the M6 due to it's built-in meter - call me lazy

, otherwise I probably would have went with an M4.
I've also heard very good things about the Voigtlander lenses. Some Leica guys even claim the 21 to be better than Leica's own (at what? 1/3 the price?). My favorite Nikon lense has always been my 20mm, so I think the 21mm will become my 'normal' lenses. That's one thing I miss with digital - the ultra wide angle. I do have an 18mm Nikon ED for my S1 but I think that converts to 28mm or so in digital - OK, but not quite wide enough for my taste. -- Curt
