So I found a guy on CL who's looking to swap his D70s body (plus battery, charger, and comparable memory card) for my Canon G9. I'm definitely not a photographer, but I have a lot of fun shooting with my brother's D60 and while I do like the G9, I prefer the feel and on-the-fly adjustments I can make with a proper DSLR. Plus, this way I can share my brother's lenses and stop bugging him to use camera. So, two questions: 1) Is it an even trade? Or is the D70s too old to consider? 2) What kinds of things should I be looking for when inspecting a used body? I asked him about the # of actuations, how he used it etc etc, but any other pointers would be nice. If it makes any difference at all, I plan on pairing it with the nifty fifty lens (50mm f/1.8 I think?) that my brother also has and I enjoyed using, or the new Nikkor 35mm f/1.8G (http://imaging.nikon.com/products/imaging/lineup/lens/af/dx/af-s_dx_35mmf_18g/index.htm) Any thoughts or input would be appreciated, thanks guys.
