The FB-28 Ball Head from Sunwayfoto is the smallest ball head in the FB line but features impressive locking strength. It utilizes one locking knob to control both friction on the ball and the panning movement of the base. The Arca-swiss design clamp opens between 37.25-41.5mm and features a bubble level. The head offers a single notch for vertical shooting and is built from all metal materials for smooth operation and durability. It provides a load capacity of up to 26 lb. Mounting holes on the three sides of the clamp are available to attach an optional offset bubble level.
