Purchased it with my 1D thinking I would get lots of use out of it, but I do not even own a tripod suitable for this. Hopefully it finds a good home.
Markins Q-ball M10 is a best balanced ballhead between its performance and weight. It is very compact and weighs less than 1.1lbs, but it is strong enough to support a large SLR camera with a long and fast telephoto lens. It is an ideal choice for active outdoor photographers.
All-in-one type ballhead that comes with a quickshoe QR-48 EDIT The larger QS-60 is included, sorry for the mistake EDIT
Super-strong and smooth bi-axial progressive locking mechanism free of lock-up problem
Amazing 90lbs load capability while weighing less than 1.1lbs: this translates to an incredible over 80 load/weight ratio.
Fluid style main tension knob (patent pending) for smooth and easy operation
Engraved degree markings for panoramic photography
Beautiful and tough hard-anodized finish
Fits all standard monopods and tripods with a 3/8" bolt
