Manfrotto 057 Pro Head Ball with RC4 Quick Release Plate

This 057 Magnesium Ball Head from Manfrottofeatures an integrated RC4 quick release cam lock and a 410PL Quick Release Plate. Compatible quick release plates can removed from the head by pulling the cam lock's spring-loaded lever, which also allows the plate to be instantly reattached.

The 057 Magnesium Ball Head with 410PL Quick Release Plate has a load capacity of 33.1 lb and can be attached to tripods or other support systems that feature a 3/8"-16 mount. By loosening the 057's primary locking knob, its ball-and-socket joint can be quickly swiveled, angled, fully tilted, or returned to its upright position.

Toward the ball head's base is a secondary locking knob that controls the ability to rotate the head 360°. An additional knob opposite the secondary locking knob can be rotated to apply tension control to the ball-and-socket joint's movements. Finally, a two-position slide-switch at the base of the ball-and-socket joint allows it to be tilted down to either a 90° or a 103° angle before it is locked into place using the primary locking knob.

The ability to tilt the ball-and-socket joint down to angle beyond 90° can be used to quickly level a camera placed on this 057 Magnesium Ball Head without having to adjust the tripod the ball head is connected to.
