I have the lenses from my rebel slr and want to keep them to use on a NEW digital by Canon. I am looking for a camera that can do pixels well enough to enlarge to poster size prints. Anyone used one or know of one that can give those results but not cost a fortune? Planning to start a stock photo site and need to have high quality resolution for the small photos and also potentially poster size. Advice? Also, advice where to get the best deals other than ebay?
