<I am thinking about getting the N90s battery grip, primarily for the button to ease shooting verticals. Any opinions on it? What is the model name and what is it going for? Thanks!> I have the N90s with the MB-10 grip and never use the camera without it attached. For me (average to large hand size) it makes the camera much more comfortable to hold in either the vertical or horizontal. In fact, I find it much more comfortable to hold in the vertical position than my F5. It is very contoured with more to grab onto. Of course it adds weight and size to the camera, but to me this is far outweighed by the benefits. Regards, jjhasluck
