Good enough resolving power.

Below is a typical action shot I took the other day. No special lab conditions just a tripod used to steady the camera. Shot @ ISO500 1/200 sec f6.3 300mm. I focused on the most static part of the body as the head was swinging in all directions to survey the scene and check me over. The depth of field was about 0.7" ( I would of normally shoot at f8 in brighter light ) so the eye area is not as detailed as I would of hoped for. But non the less you can see the humble 10Mp sensor of the Canon 40D has picked plenty of detail.

The image is a 100% crop and the full frame version is in the insert.

I've been shooting digital for the past 6 years and in general the results have been far superior to my film work.
