Optical adaptor for B4 mount lens to large sensor camera
Use B4 mount box lenses or other long-range zoom lenses with a B4 mount on your PL-mount Super 35 camera with the TL-OM4K OptMag Plus B4 Mount to PL-Mount Expander from Musashi Optical. B4-type lenses are perfect for sports and other event coverage where the camera cannot get close to the action, and most are capable of beyond 4K quality up to 5.7 and 6K with Super 35 cameras.
The OptMag Plus OM4K has a new system of AR multi-coated optics designed to effectively increase the image circle of the lens while maintaining the same angle of view as the B4 lens on a Super 35 sensor camera and keeping the highest level of image quality for modern 4K and beyond recording. It is simple to use and mounts between the camera and lens to maintain all focus and other controls of the B4 lens. The OptMag Plus is compatible with cameras such s the ARRI ALEXA, Sony PMW-F3, F55/65, RED RAVEN, Panasonic VariCamLT in CineLive Config, and Canon C300PL.
