Metabones Nikon F -> Micro Four Thirds Speed Booster brand_Gitzo Includes EW-78C lens hoodThis Metabones Speed Booster lets you mount Nikon F lenses to a Micro Four Thirds camera, while also giving you an extra stop of exposure and reducing the crop factor to 1. 5x. That's good! No autofocus or electronic communication: this one's mechanical only. Light cosmetic wear, good function.
