Quite interesting that ckodonne reports the same minimum shutter speed for his 300mm lens!
Thanks for that bit of input; I knew from my own experience with the 300mm that anything under 1/500 produced some noticeable motion blur...I always shoot 1/750+ to play it safe if I can...though that may be unnecessary now. I used to shoot on the Canon 30D which has a 1.6 crop sensor, but now I have a full-frame sensor. Good to know that I can get a little more versatility out of my 300mm now.
