Don't just take snapshots! Take control over your composition with increased camera performance and sharper images that will exceed your expectations! Turns your car into a tripod! The Photo Logic PL-10 Window Mount Clamp provides a quality solution to smoothly and efficiently hold almost any imaging device firmly onto a car window or other thin surface up to 1/2 inches thick when a conventional three-legged tripod is useless.  Digital or film cameras (even with long telephoto/ zoom lenses), camcorders, spotting scopes and binoculars (optional binocular tripod adapter might be required) are held steady and secure while allowing outdoor / nature / adventure / surveillance photographers and hunters to remain comfortably seated inside their vehicle. The PL-10's versatile three-way tripod pan head incorporates a bubble level, a quick release mounting plate for fast camera attachment / removal and is mounted onto a sturdy die-cast metal "C" clamp with cork cushioning to protect the mounting surface. The quick release mounting plate offers a standard 1/4"-20 threaded camera screw plus a retractable video camera stabilizing pin. A long, easy-to-grip handle lock provides front to back tilting (altitude adjustment) while a large lockable knob gives 360 degrees horizontal rotation (azimuth adjustment). In addition, a lockable hinge offers 90 degrees of side tilting to quickly position your camera or other imaging device for vertical shots. Main Reasons to use a Window Mount Clamp: Get maximum image quality whether you are shooting stills or video. Extremely Sharp pictures even at the shorter focal lengths and macro applications, never mind at the extreme telephoto settings where every little movement is magnified and reduces picture sharpness. Avoid camera shake from hand holding, and never worry about shooting at slower shutter speeds.
