Review on Annsm Heavy-Duty Aluminum Alloy Panoramic Tripod Gimbal Head for DSLR Cameras with Telephoto Lenses – 360 Degree Movable Arca-Swiss STD 1/4” Quick Release Plate – Max Load Capacity of 40 lbs / 18 Kgs by Sandra Egan

I bought this for use with Nikon 810/750 (2lb) bodies, specifically the Sigma 60-600 zoom (6lb). unlocked. It also has a very viscous lubricant that makes it difficult to pan/tilt when tracking an object. There are many videos on YouTube outlining the process of removing and replacing with a lighter lithium, a really simple process would increase the shake. Also, my to-do list is already cutting into my camera time, so I really didn't want another project, one Off the shelf solution. In the end I returned this and got the Benro. Three times the price, less than half the cost of Wimberly and no new mortgage required for an RRS unit I think Benro uses a larger bushing rather than a needle bearing but it's very well done Oscho. Tracking with that big lens. All in all, if price were my main concern, this stabilizer is well made and very reliable. if locked. design, nothing more. If that's your priority, this is the deal. Otherwise, it becomes a side project of the store.
