Im using a 501C with mostly an 80mm lens for most of my fine art work. I also own the 150mm lens which seems better for exterior photos where as I use the 80 for interiors as my "normal" lens. I tried the 50, its just too wide for my style. So I am happy to own just those two lenses. After exploring the possibilities of a different camera (fuji, bronca) for everyday use, something to knock around with, put in the car, etc, I decided to stay with the same system and maybe add on to it. But having just one body is probably not the best idea anyway, always good to have backups. The 501C that I bought was in mint condition and hardly used as was the lens, so it wasn't cheap. And being the fanatic that I am, I still had it professionally serviced. So for a body to bang around with, maybe with the 150mm lens living on it, what would you recommend? Should I look for another 501 or should I go down a step to the 500? Even though I say its to "bang around" I still need something reliable and of high quality. The 501C that I have is more for the indoor portraits and this added body would be for outdoor stuff. Thanks!
