Take a look at my website and the answers are all there!!! Seriously..how can you compare 7D with 1DM3, they are worlds apart. 1DM3 for sure!!! I have sold away my 1DM3 recently for the 1DM4. I can tell you when I tested the 7D in one of the shop, the AF feels much slower than my 1DM3. For wildlife you really need fast AF not just fps. Get the pro series and you shall not regret. How do you think you are paying so much for the 1D series? There are many reasons behind it. The pricing are there for a reason. You are paying for quality product....sorry should be PRO camera.
