Ok so my grandmother has just been wheel-chair bound and asked me last week if I wanted to trade her Canon 20D for my Nikon D50. She wants a lighter camera and I am the only other family member with an SLR. I was looking on DPReview and there were goods and bads for each, I just don't know what to do... The Canon has a smaller screen... The Nikon has +-5 in Exposure compensation, Canon +-2 The Canon has more MPs... and so on and so forth.. Another thing is her lens array, I think she has the kit and a Sigma 70-300... I have a semi-broken kit (still works), sigma 70-300, and my fav, 50mm f/1.8... I leave for NYC 3 4 days after Christmas, and wanted the 50mm for shooting in Times Square for New Year's but maybe I would have to make a stop at B&H, oh darn I just don't know what to do, I'm getting the Canon XSi in January in a start-up package for The Art Institute, so I thought maybe a good time to switch over, but then again I want to be fluent in both sides so I don't have to pick and choose, so when I get really rich I can have both the 5D Mark ii and the supposed D400 Just looking for some opinions...She probably wants to know by Christmas, since that is the next time I see her.
