Just wanted to hear some thoughts as the 5D is available used now for around 1100-1400. I have read opinions of the 5D having nicer image quality and nicer to use than a new 40d or 50d. Since the prices are not so far apart from crop and full frame, do you think crop cameras will start slowing down? Or, maybe crop cameras will always be around for wildlife work as you gain 1.6 with lenses? Do you think in 5 years, it will be mostly full frame?
