That lens is still a darling to AF today - even adapted to L-Mount but a drop that left no visible marks of the lens body must have broken the glued MF clutch so unless I undertake a significantly complicated repair there is no MF available - but otherwise it works fine. It features IS lens stabilization, EXIF transmission, electronic auto iris with an integrated Type-C upgrade port to enables its stronger compatibility with more new camera/lens models in the market.

L mount cameras including: Leica SL SL2 T TL TL2 CL cameras; Panasonic Lumix S1 S1R S1H cameras; Sigma FP cameras, etc.
