This is a mid-sized ball head (about 12cm tall and 5cm across at the base) that should work well on most standard or travel tripods. It's well made of metal (except for the lock handle) and should support most normal-sized cameras. 3/8" thread (with a 1/4" adapter) thread in the base for tripod mounting, reversible 1/4"-3/8" thread up to for your camera. In excellent condition.
