I see it as my pre-reviewers, and hold times together, in my view: - It is a nice feature for panoramic shots or fast motion recordings with swivel - Even with my EOS 1200D with however light lens (18-55 mm) stable - Unfortunately, the speed can not be controlled, but only the angle - Depending on the angle of the swing lasts 15, 30, 45 minutes or an hour - ie you have to bring a lot of time under certain circumstances
