"None of the above"... I shot film on my K1000 for many years (and still do) but until I got my DSLR, only had three lenses - two cheapie zooms (35-70mm and 70-210mm) and one prime (Sigma 28mm F2.8, which is probably going up for sale any day now.) Now in the 50/55mm range, I have four of 'em... my usual FA 50mm F1.4, an M 50mm F1.7, an M 50mm F2.0, and an M42-mount Takumar 55mm F1.8. Oh, and a quite nice M42 Vivitar 55mm F2.8 1:1 macro, made by Komine.
The "M"s came in collections bought recently off Craigslist and will also be going up for sale very soon; I just don't need 'em all! And I need to raise money for future lens buys...
