Offered is a Schneider-Kreuznach G-Claron 150mm f/9, a classic German large-format lens from Schneider-Kreuznach, well regarded for its sharpness and suitability for technical, architectural, copy and large-format photography. The lens is presented in its original black finish with the characteristic Schneider-Kreuznach lettering, aperture scale and mounting flange. The overall exterior is in very good condition, with only minor signs of storage/use visible on the barrel and mounting board. Optical condition The glass appears generally clear, and no obvious scratches are visible on the optical surfaces during inspection. Note: Please note that when examined under strong illumination, small internal particles/specks are visible, together with a slight grainy/uneven appearance in the glass. The exact nature of this is uncertain and may be related to internal dust or the optical coating. It is therefore reflected honestly in the description and shown in the photographs. There is no claim here that the optics are completely dust-free or optically perfect. Mechanical condition The aperture mechanism appears intact and working with tactile clicks, the aperture scale clearly visible. The barrel and mounting flange are in great overall condition, with normal signs of age and handling.
