Aperture & focus actions have a precision feel that is unmatched with modern day lenses (bar Leica). The optics are bright and clean NO haze, NO fungus. The finish of the lens is Chrome over Brass, this gives the lens a weighty and very solid quality feel.
Add an easily found Leica Screw to M mount adapter and this lens will attach direct to your modern day Leica M camera, includes Leica M8, M9, M240, M10 etc. Can be used with other Digital cameras subject to the correct adapter. The optical quality of this lens is SUPERB, very sharp with strong contrast and high resolution.
