The geared movement allows users to frame images precisely - one micro step at a time - on all three axes. The knobs ensure ergonomic comfort even during extensive usage. In addition, in order to make large framing adjustments, the locking system can weighs only 1.65 lbs., but can support a payload of up to 8.8 lbs. Its adaptor body-a strong, rigid techno polymer - makes this head the lightest and most precise ever created by Manfrotto. The xpro geared head features the most common photographic plate in the world so there's no need to use different plates when switching to other Manfrotto supports.
