Wow, Col, these are fantastic - one would never know the ISO was at 10k! I especially like the female blackbird (No 1) and No 4 of the squirrel. I've been doing some landscapes - who is to say that's not allowed? (Many, I'm sure!) I never thought I'd say this but I reckon my 70-200 II may be redundant now.
I am thinking along those lines as well....I will pick up my one week rental on Thursday. Good timing too. Practice session this weekend for the Daytona 24 race.
