Nice squirrely shot. ; That 50-500 is looking decent - better than the last version from what I've seen! My new 300mm F4 APO G lens also seems to love squirrels so sharp they can cut you:
Tim. we gotta get out to forsythe in a month when it is cooler and the hawks and eagles are out. would love to see what you get with the sigma and the 5d
So, you go all the way to Florida, visit Animal Kingdom which is full of exotic animals and you take a picture of a squirrel? ; ; Just joshing ya, very, very nice.
