This is the very fast f/.95 50mm Hyperprime with Micro Four-Thirds (MFT, M43) mount. Has been carefully handled and is in terrific shape. Pristine glass, smooth mechanics, and has spent most of its life packed in a Pelican case.
SLR Magic Cine 50mm f/.95 - $850 (Hyperprime)
I have the original box and packing material and was the sole owner, purchased directly from SLR Magic.
