Metabones Contax/Yashica to Micro Four Thirds Speed Booster
A genuine Metabones Speed Booster adapter to mount Contax/Yashica SLR lenses to Micro Four Thirds cameras. A Speed Booster slightly reduces the crop of your lenses (from 2x to about 1.5x) and adds an extra stop of light, to boot. Not a bad bargain! In near-new condition, with original box.
