I'm planning on finally upgrading from my 40D this year. I do high speed action photography of running dogs outdoors, and shoot a lot of photos every year so fast/accurate focusing and shutter life are the biggest priority, with low light being a close second. My 40D is at somewhere around 160K photos now, and it's past time to replace it.
The 7D is supposed to be the flag ship but there seems to be a lot of good arguments for the 70D over the 7D, and the 7FPS vs 8FPS is not an issue, nor is the cost difference. The one caveat that I can see so far is that the 7D is rated for 150K shutter actuation's, while the 70D doesn't seem to have a number provided. Has anyone used a 70D this heavily yet? Any thoughts?
I also understand there may be a MKII of the 7D coming out and that could change everything of course.
