Brand new Viltrox NF-M43X 0.71x Focal Reducer Turbo Booster, used once but have since sold my micro four-thirds camera, so I no longer need this adapter. Works a a Nikon F-mount lens adapter to micro-four-thirds m43, but is also a focal reducer which provides more light to the sensor and gives you a more true focal length of the lens you're adapting. Comes with original box, and rear & front caps.
