Mike, I remember precisely when my time came to switch from a fast prime lens to a "kit zoom"--actually for me it as a pair of zooms. That as in 1986 when I left my Canon A-1 behind and purchased a couple of Minolta Maxxum 9000s. I returned to fast primes when I bought a 40mm/1.4 with my Cosina Voigtlander Bessa five years ago. Now my Sony Alpha kit (which superceded the Minoltas includes a Sony 50/1.4, a Minolta 50/2.8 macro, and a nice compact Minolta 28/2.8, which is fast becoming my primary prime!
