The primary difference between the 5D Mark III and the 5D Mark II or 6D is the amazing autofocus system, which covers a large part of the frame and tracks moving subjects with amazing accuracy, surpassing even the 7D and 70D. For that reason, the 5D Mark III is the right choice for sports and wedding photographers, whether serious amateur or professional. Those tasks require tracking moving subjects, often in low-light conditions, and the 5D Mark III will give you more in-focus pictures than any lower-end camera. However, the 5D Mark has the exact same image quality as the 6D and 5D Mark II, which are far less expensive. Therefore, if you’re not tracking fast-moving subjects, choose one of those two bodies, and save the rest of your cash for lenses and flashes. The 5D Mark III isn’t the best choice for most wildlife photographers. Instead, I recommend purchasing a used 7D, and saving the rest of your budget for lenses. The 5D Mark III is excellent for wildlife photography when you can get very close, so if you plan to be spending hours camouflaged in a blind, the 5D Mark III might be a better choice for you. The 5D Mark III supports autofocus up to f/8, allowing you to attach a teleconverter to a lens such as the 400mm f/5.6 and still autofocus. However, you can only use the center autofocus point, which limits composition. You should also consider the 36-megapixel Nikon D800. The D800 has 15% better image quality, making it a better choice for landscape and commercial photographers. It’s a better choice for most wildlife photographers, too, because the DX crop mode provides a 1.5X teleconverter effect while still capturing 24 megapixel images—more detail than even the 7D. http://www.youtube.com/watch?v=JSJ4mrTzDTg http://www.youtube.com/watch?v=ga07x8SsANU https://www.youtube.com/watch?v=D3Ums46kKsE https://www.youtube.com/watch?v=Jqc5jwR0uuw https://www.youtube.com/watch?v=VR7Kjeq2aH4 https://www.youtube.com/watch?v=NjR2OztuXtA https://www.youtube.com/watch?v=8Xrslc5zsPI https://www.youtube.com/watch?v=Gq3ISUHsfsQ If this helped you, please use the links to Amazon or B&H at the top of the page to order it–we get a few cents from every dollar and put that towards future reviews!
