Took the plunge and purchased the Sigma 70-200mm 2.8 OS

I was actually fallowing that thread, that lens seems really sharp even at 500mm. Was meaning to ask how your camera handled the weight of that 150-500. I saw a review on youtube and the guy claimed that if you didn't support the lens with your hand while shooting freehand that your camera would snap in half. I'm assuming he was just being overly dramatic.

Dont want to hijack Ballistics thread, but I have not had any problems...I do carry very carefully though.
