Here is a link about the crop factor issue.

I also have a 40D and 7D. I too love to take motorcycle racing pictures. These were taken with my 40D. http://www.flickr.com/photos/pics_by_adrian/4326358970/in/set-72157623212405747/
What the crop factor does is simply magnifies the focal length of your lens by 1.6 which in simple terms means a 100mm lens becomes a 160mm lens.
If your happy with your 40D there is really no need to change (but 18million pixels is handy when cropping in Photoshop), just buy some better optics, a Sigma 120-400 would be ideal.
I'm still learning the 7D but so far I see now't wrong with it, bear it in mind that critics of one brand of camera may well be enthusiast of another brand.
Hope this helps

http://blog.photoframd.com/2009/10/20/canon-7d-the-crop-factor/ Great article and well explained. Just because the camera does crop it doesn't mean you don't get everything you see in the viewfinder - you do.

That's why I LOVE my 7D, I get much more from my prime lenses and with extenders it gets even better. The AI Focus is very quick and sharp and keeps me in focus under all circumstances that I have come across so far - three years of wildlife shooting with the 7D.

If you want magnification, it does not give you a longer focal length. It gives you the same focal length but with a narrower field of view.

Quote:I've had my 7D for three years now and LOVE it. I do mainly wildlife photography and it does everything I want of it. I had a few teething problems but this site pointed me in the right direction and since then have no complaints.

AI Servo focus works well for subjects moving towards or away from you. I'd never have got this shot with fixed focus, he was really intent on getting at me!


your shot is not a good advert for the 7d , its not in focus :-( mind that link shows a great shot .
