Some excellent advice Joe - thanks. I shoot a 20D as well and found that shooting with centerpoint focus and centerweighted metering has helped as well. I have also bumped up the saturation and color tome in the camera settings and that has helped with less effort needed afterwards in PhotoShop CS2.
I'd love a 1D Mk III but it's a bit more than is in my wallet at the moment

What recommendations do you have on a long lens - the Canon 100-400 IS is fairly common and well thought of but wondered if you might have any experience with others such as the Sigma 200-500? And finally, do you use the IS feature when shooting? Any comments on IS (image stabilzation) use?
Enjoy the Day! Mark

Personally I don't use anything but Canon L lenses, but not everyone needs that. Photography keeps a roof over the family's head, so the best glass is the choice for me.
The only time I use the IS setting on my 400 2.8 is shooting at airshows. If it's a comfortable thing to buy it, it isn't a bad idea at all. Consider that you want to get a sharp image of a moving object while you're panning as well...it's a pretty good idea if you can justify the cost.
The primary thing I'd look for in lenshunting is anything with higher quality glass...Tamron's LD glass, or...well...umm....Sigma has it too, but I can't remember what they call itheirs. Better glass will give you a sharper photograph...period. better glass eliminates what's called chromatic abberation.
Basically, it works like this. When light hits the front element of your lens, it seperates into the natural colors of the spectrum. Because the colors of the spectrum are different wavelengths, they travel at slightly different speeds down the inside of the lens. When the light hits th back element, it refocuses the light into a usable form. But the problem is this...since the wavelengths of light travel at different speeds, they reach the rear element in a slightly different plave than what they started.
In other words, with non-corrected glass, the longer you zoom out, the less sharp your photograph is going to be.
THe lens glass I mentioned above corrects for that. AN IS lens without corrective glass is always going to be softer when it's zoomed to its full length than it will at a shorter length. With that in mind, if it's a choice between IS without corrected glass, or non is WITH corrected glass...go with the better glass.
*NOTE* THis is not anywhere near as much of an issue with a shorter zoom lens.
