A Kowa Infrared 50mm f/1.9 came to us from a client who had a specific use for it in a more cinema-friendly application. It received an 80mm front ring for standard matte box use, as well as seamless focus and iris gears machined from Black Delrin.
This unique lens is designed for smaller format sensors but would work well on a Micro 4/3 camera. It's been converted from M42 to Canon EF mount using a simple adapter. It's full manual controls and rugged build will make it an ideal lens for motion picture work.
