Greetings, I know I have read on the ND of some people trying to use the N90s+MB10 on a tripod and reporting MUCH better stability once the MB10 is removed. I have a gut feeling it's gonna be the same with the new F100/MB15 combo. Just look at the picture on Moose's site!! (http://www.moose395.net/hot.html) You can even see a gap along the back edge between the camera and the booster. Just imaging the torqe w/ that 28-70/.8D hanging off the front in a stiff wind!
