This is due to the revolutionary design of its grip handle which incorporates the ball lock lever.A friction control wheel lets you regulate the power of the blocking mechanism to match the weight of your camera and lens. The 322RC2 is made from magnesium for lightweight performance, and is designed to keep the weight of your equipment as close as possible to the tripod's center of gravity by way of its reduced height. It is this fact, matched with the precision construction of the 322RC2 that gives the head its load capacity of 11 lbs (5.5lb capacity when in the vertical position).The 322RC2 comes complete with a built-in bubble spirit level and quick release camera plate (standard 1/4 - 20" screw, with secondary safety pin).The 322RC2 is suitable for use with 35mm or medium format cameras.
