I've done a simple field test. (1)Fu Hai Feng pics was taken by Canon 30D +EF 70-200 f/2.8 L USM Setting: 1/320, f/2.8 Aperture priority, ISO 1600, focal length 200mm, tungsten WB. (2)Lee Chong Wai pics by Nikon D70s+AF 80-200mm f/2.8D ED Setting: 1/160, f/2.8 Aperture priority, ISO 1600, focal length 125mm, auto WB. The outcome of the photo is comparable at size 8"X10". The acuity of Nikon photo is better, while the color noise of Canon is much lesser. The 5 fps of 30D is very useful to increase the chances of taking good pics, and using the tungsten wb & aperture priority setting is very reliable. The wb of over 90% of the pics were corrected. Comparing the auto wb & aperture priority in D70s, the files were very fluctuated with different grade of yellow to brown color which consumed much time in post processing to correct every file. The results were similar when I took pics at indoor badminton court without spotlight. I wonder whether D200 can perform more stable. I was very fortunate to borrow a press pass for a while to take court side photo in SF of China Open. It's the first time I can feel CJ, CH, XZB, ZYW were very close to me, their footwork were so fast. I out-focused many good pics as I was not familiar with the AF system of 30D. Finally, I found AI servo with 9-focusing point, shutter priority at 1/400, ISO 1600 for court side pics was helpful. It will be much better if I got f/1.4 or f/1.8 primes.
