The current photography poll question at Shutterbugs.biz has to do with camera equipment obsession - real or imagined. Upgrading to a new camera every year seems a bit over the top to me and I wonder if the biggies stayed with the same gear once they found what worked for them. I suppose cameras were simpler then and system upgrades weren't released every other week. Ralph Gibson has used Leicas for 45 years; not sure how many models he's gone through over that time period though.
Bottom line, a new-fancy-top-of-the-line camera will not produce a great photo all by itself. And photographs produced with half-century old gear still hang in museums, drawing 'ooohs' and 'aaahs' from viewers of all ages.
