Canon 450D to 7D AF Question?
Oct 16, 2010

I think I may have to move on from my Canon 450D.

In my retirement, I have enrolled as a member of the Edinburgh Zoo and I have started to take more pictures of Zoo Wildlife. The 450D does a great job but I find that about 35% of my shots are not 100% in 'optimum' focus which is a pity.

I am considering moving to a 7D (again a 1.6x crop sensor) which would give me the reach that I want with my 300mm lens and greater pixel resolution on the 7D image than a Canon 5D MKII or even the 'rumored' Canon 5D MKIII at 28Mpixels. Either one of the 5Ds at 1.6x crop (DX) on the image would not match the pixel resolution of the 7D?

Has anyone in this forum moved to the 7D.................could you please share your experiences of the AF capabilities for wildlife shots (especially at around 300mm) of the 7D, especially the % of keepers you usually achieve?

Many thanks
