Michael L. Smith made a fortune off of one photo - "Mad Bluebird". Think I'll be as lucky with the "Mad Ring-necked Duck"? :D In retrospect, I could have raised the ISO for a better shutter speed. I got away with one...
50D, EF70-200mm f/2.8L IS + 1.4x @ 280mm
Aperture priority, f/5.6@1/80, evaluative metering EC -2/3 ISO 200 WB=5100K
AI Servo autofocus, HH, no flash
Agree with your assessment regarding the ISO increase. I know the noise is a concern with the 50 but have found a way to deal with it !!! Try Topaz Seems to do a much better job than anything else, has a thirty day trial period so you can evaluate. Remember to work on the eyes of those guys, always look goofy !!!
