great moments here. Was the blue team called the "Super Skinny's?" j/k -- I am glad that you are giving me a chance to see what the sigma can do. Is yours a Macro?

The Sigma is not a macro. Unless it's a evening game, I haven't been using it much. I'm noticing a difference in AF time between it and the Canon lens I have.
Canon EOS 30D
Canon 70-200mm f4.0 L
Sigma 70-200mm f2.8 DG HSM
I tried the Sigma 80-400 as it was much cheaper than the Canon 100-400.
After using it at le Mans 24h, I took it back to the shop and bought the Canon because the AF was too slow on the Sigma. The Sigma IS was also worse than the Canon, it was only an extra £300 to fix both of those by buying Canon.
