What qualities should be looked for in a ball head before purchasing one?
I recently purchased a tripod, however I didn't realize that it didn't come with a ball head. I am (very) new to photography and want to make sure that it fits both with my camera and my tripod.
My camera is a Panasonic G3 (I don't know the thread of the tripod receptacle if that's what is needed) and a Manfrotto 190xPROB with a 3/8 inch thread.
If there is any ball head that is recommended or are they all roughly the same; my price bracket is at most $100, but ideally around (or below) the $50 mark.
