The Leofoto LH-47 Ball Head is a mid-sized ball head that will support camera-lens combinations weighing up to 48 lbs. Crafted from aluminum and hard anodized, the LH-47 has all of the qualities you would expect from a professional-level head. An over-sized, ergonomic locking knob allows 45-degree tilting in all directions and a 90-degree drop-notch facilitates quick and accurate switching from the horizontal landscape position to vertical portrait orientation. A separate tension knob is provided to apply the appropriate pressure that safely corresponds to the weight of your camera. A third knob loosens and locks the panning base which is laser-engraved with markers every 2.5 degrees from 0 to 360 degrees.
