For those of you unfamiliar with Panoramic, QTVR, and Super Megapixel photography the need for a panoramic tripod head may not be understood.  A standard camera tripod is designed to hold and rotate a camera around the tripod mounting hole of the camera.  This hole is located arbitrarily somewhere on the camera body.  However, to take accurate panoramic photos it is important that the camera be mounted and then rotated around what is called the optical center (sometimes called the nodal point or entrance pupil) of the camera's lens.  This ensures that optical distortion, called parallax distortion, will not be introduced into your pictures before they are then stitched together using computer software.  Many people use panoramic tripod heads to not only take wide vista shots, but also to take 360 degree QTVR photos and photo mosaics (multi-row megapixel panoramas). Most panoramic tripod heads are constructed of metal, are quite heavy and very expensive due to the complexity of their designs.  The Panosaurus was designed to meet the needs of the hobbyist and professional who don't need the overkill precision of the most expensive heads and would prefer a light weight and simple to use alternative. The Panosaurus was developed and has evolved during two years of research to attempt to create the most flexible and easy to use panoramic tripod head system available - that will accommodate the widest number of camera and lens combinations possible.
