Hey Guys,

Nice back and forth that was going on. I found it very interesting.

Tony,
I did not realize you had the sigma 120-300 F2.8. How do you like it?

Donald,

As to the image of the captive wolf, I still really like the shot a lot. I think that some of the vividness can be fixed in photoshop...though you can obviously never completely replace what goes through the lens. Curiously, which camera are you using? A D1? I had debated the purchase of a 50-500 but have always balked at it.

Cheers
James
