The Manfrotto 494 Mini Ball Head w/RC2 QR Plate is a
lightweight ball head that's perfect for smaller cameras (maximum
load--8.82 lbs). It's got a quick-release plate, a newly designed
friction control knob that allows micro movements without engaging the
head-locking mechanism, and a locking mechanism that will lock the head
in both the +90°/-90° tilt position and the 360° panning position.
