The SLR Magic 50mm f0.95 Hyperprime is a super fast manual focus lens for the Micro 4/3 mirrorless cameras. The f0.95 aperture, which allows for an extremely shallow depth-of-field, in combination with the 100mm-equivalent focal length makes for a great portrait lens. With such a wide aperture, shooting in very low light is also possible. It features a stepless aperture ring with a locking screw to lock your chosen aperture in place. The manual focus ring is very smooth with a nice throw, which will work wonderful for video work as well as still photography.
