Looking to extend the investment in B4 mount box lenses or other long range zoom lenses with a B4 mount? Then Musashi Optical has the expander for you. These types of lenses are perfect for sports and other event coverage where the camera cannot get close to the action and most are cable of Beyond 4K quality up to 5.7 and 6K with Super 35 sensor 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 taking lens on a Super 35 sensor camera. All that while keeping the highest level of image quality for modern 4K and beyond recording.
