I have recently found myself getting into wildlife and birding. I love it! I have been thinking about getting the 5dmk3 for some time now. But with my recent love I figured I would need a fast cropped sensor body and the get the full frame 5dmk2 for landscapes and portraiture. I do own a 50D right now. So my question is which set should I go with? Should I go for the 2 cameras or just the 5dmk3? Will my 50D be good enough for what I want to do with birding and wildlife? Better yet is the 5dmk3 capable of handling my needs as well? Thank you in advance for your opinions, they are greatly appreciated.
