The GH3W-15 3-Way Geared Head from Oben provides three independent gear movements with fine-tune precision for pinpoint aim. Integrated bubble levels assure perfect alignment with the horizon, regardless of the camera's vertical or horizontal orientation. When the gears are engaged, the camera is locked into place and won't shift out of position, which is a common problem with traditional ball heads. This head is also ideal for applications where micro camera adjustments are a must, like close-ups, macro, and product photography.
