SUNWAYFOTO XB-52DDHi is based on XB-52 and replaced the Screw-Knob Clamp with Panning Clamp. Precision Panning Base with integral clamp and bubble level for smooth and level panning. It's your ideal ball head for shooting panoramas.
 
The scale with laser-engraved centering index marks can precisely master any angle variation during each shoot in horizontal rotation?the aligned scale of quick-release plate can accurately control the nodal point during the panoramic photography in different focal lengths. So the panoramic photography could be more accurate and high efficient.
 
When taking panoramic shooting, you need to make sure all the pictures are level.
However, you can’t always put your tripod on the level ground. When using our panning clamp, you don’t need to level the tripod legs. Just level the panning clamp, you can take panoramic shooting easily.
