Bit boring to say always high quality lens , superb built quality. A professional product trully. It makes contrasty , very sharp images. I beleive good as than any other top maker fast lens like Carl Zeiss or Nikon. Little long for Micro 4/3 cameras , but I can live with it. Pretty rare , grab it if you find it.
Lens is usable with Konica AR cameras. It is mountable on any micro 4/3 camera bodies (Panasonic,Olympus). Konica AR->micro 4/3 adapter need for usage. I am against lens conversion these are rare and such a good lenses please try to keep them in genuine stage and don't ruin them with silly conversion.
