QC-707 is a moderate wide angle converter for video cameras made in Japan. It allows, among others shoot in cramped rooms where the standard lens didn't let you cover the whole scene. QC-707 is a converter with a factor of 0.7x. This means a noticeable enlargement of the filmed frame while maintaining almost intact geometry. For example, a 50mm lens with the QC-707 mounted gives the same image as a 35mm lens. QC-707 is a solution for anyone who has not been able to frame the entire filmed scene at least once. It is worth noting that this solution also allows you to get closer to the filmed scene, e.g. when filming children. Mounting the QC-707 is very convenient. The SNAP-ON quick mount system allows the lens to be attached to the lens with a single hand movement. This model works with lenses with a mounting thread from 27mm to 37mm.
