This is the very fast f/.95 25mm Hyperprime with Micro Four-Thirds (MFT, M43) mount. Has been carefully handled and are in terrific shape. Pristine glass, smooth mechanics, and has spent most of its life packed in a Pelican case. Exhibits a slight bit of play in the focus ring, but hasn't impacted its use.
SLR Magic Cine 25mm f/.95 - $310 (Hyperprime)
I have the original box and packing material and was the sole owner, purchased directly from SLR Magic.
