The MVT535AQ's locking leg angle selections hold each leg in place until you adjust its position, with the flip locks allowing you to independently adjust the height of each leg. The flip locks are adjustable, allowing you to tighten them in order to counteract any slippage or looseness, which is not uncommon with flip locks. The legs incorporate metal spike for extra grip on soft surfaces such as sand, dirt, or rocky terrain. When working on hard, slippery, or delicate surfaces you can spin-down the rubber spike covers for increased grip.
The Manfrotto 502AH Pro Video Head with Flat Base is an affordable yet remarkably fully featured professional head that represents an advance over the popular 501HDV, with sturdier construction and featuring Manfrotto's patented bridging technology (inherited from the 509 and 504 heads). This head is designed for executing cinematic moves with compact camcorders and DSLR cameras.
