I drove down to Eldorado today to try out my new Canon 7D. Suzanne Johnson had told us there were quite a few ducks that had arrived. This camera is amazing. I used my 500mm with a 1.4 teleconverter attached. The auto-focus was instantaneous. The 8 frames per sec was like a quiet machine gun. I was shooting at aperture priority at f5.6. These subjects in the following photos were at least 100 yards distant. They were about the size of my focus point in my view finder, so obviously I had to crop extensibly to get these close-ups. Check ’em out.

Thanks, Mike.
This camera is continuing to impress me. I too, am amazed with lack of noise. Thanks for your kind words.

Hi Bob,
If I understand the amount of cropping you did, these photos have amazingly little noise! I am truly impressed.
I look forward to seeing many more wonderful photos from your new toy!
