Congrats on the purchase. :-) At about 600 grams, I'd say the *istD mount will endure the weight quite well. However, if you plan to use it on a tripod, the balance is almost as important as the weight. Mounting the camera to the tripod will give you a lot more vibration than mounting the lens tripod collar. It's somewhat a contradiction of terms to have a walk-around kit ready for a tripod, but I know exactly what you mean...:-) I don't know how that particular collar is removed, but is it an alternative leave the collar attached to the tripod, and release the lens from the collar rather than from the tripod? cheers, Jostein
