The Manfrotto 498RC4 Compact Ball Head with RC4 Quick Release and 410PL QR Plate
is constructed of die-cast aluminum, strong enough to support an SLR
camera with a medium lens, and light medium format cameras. It has a
single repositionable locking lever for 360° panoramic rotation and ±90°
tilt movement, plus a friction control for precise positioning. Cameras
are attached to the ball head with the 410PL Plate and RC4 Quick
Release with 1/4'' male threads. The head to tripod attachment has 3/8''
female threads. Additionally, the Quick Release has a safety system to
prevent an accidental detaching from the head.
