My wife and I are going to Africa and, of course I'm bringing my gear. I am currently shooting with a 5D Mark3 and plan to take my 70-300L (among others) with me. If I want to get an effective focal length of 480 mm, which will give me the best results for large prints a)shooting with 5d and cropping image, or b) buying a 7d, and relying on the crop sensor to give me the extra reach I'm looking for?
Don't bog yourself down with equipment. You will enjoy the trip much more.
Use your 5D III and 70-300L and a WA add the 400L 5.6 A little cropping doesn't hurt and you will appreciate the handling and save some money.
