I remember reading an interview with a British "glamour" (Playboy- type) photographer. Same kind of story, one camera (Nikon something) and one lens (300mm). Didn't ever use anything else.(posted 8721 days ago)I find that the best equipment for me is the equipment that gets out of the way the fastest. Changing gear makes that impossible. I bought a Konica Hexar a few years ago. Different handling from anything I was using (manual rangefinders), took at least a year before I got to where the results were what I wanted.
By the way, my friend with taped-together cameras does profesional work with it.
