This is a newish lens that Samyang have brought out. It is specifically designed for mirrorless, unlike many of their other lenses which are designed for DLSR and have a mirrorless mount fitted. It is Manual Focus and manual aperture only. I bought one a few days ago in the hope that I could replace my Cosina 24/2.8 (Nikon AI fit) with something smaller, lighter and faster. So far, I think that this lens will be a keeper and will become my walkaround lens on my Fuji X-E2.
