The Leofoto G6 provides pitch (perspective) and roll (leveling) adjustment via the use of a high-precision gear design that allows for hyper-accurate composition often required by architectural and product macro photographers. The horizontal, tilt, and vertical axes are controlled independently, with mechanisms below the camera, allowing you to search for the best level before taking pictures. Some photographers use them as inseperable micron motion patella to appreciate their compactness and the extreme accuracy of micro motion, especially in architecture and studios.
