Here here, Bertram. When I only had a 50, I think I made some good photos with it. When I got a 100, I used that so much I made some good photos with it. Then a 35 became my standard, the other two used very infrequently, and I made most of my best photos with it. When I got a 28, I grew enamored of it, saw its possibilities, but haven't stuck to it, so not many of my photos are very good. Plus I keep changing film. I used shoot pretty much only TriX developed in HC-110.
Thanks for the post, George; I think the real message is how he sees. The one camer/one lens formula is not a rule for him, but is an enabler of that vision. In a way it's the photographic implementation of the KISS principle. Sometimes my wife says "How many cameras do you need?" She's right.
