This high performance apochromatic optic reduces axial chromatic aberration to close to zero. Abnormal Partial Dispersion glass is used in 6 out of 8 elements for very high optical performance. The compact design reduces lens length to only 63.3mm. Vignetting was kept to a minimum. 12 aperture blades keep the aperture close to a circle shape for beautiful bokeh. The synergistic effect of the long focal length and large F2 aperture produces “large background blurring” for photographic expression.
This lens is designed for full frame VM mount rangefinder digital and film cameras. Equipped with high-precision rangefinder focusing, you can enjoy the silky operation feeling of the all-metal helicoid ring and the real pleasure of focusing using the traditional manual focus optical rangefinder. The closest rangefinder focus distance is 0.9m (depending on the camera.) This is very close indeed for a 90mm VM mount lens. It can also be used on Sony E-mount, Fujifilm X-mount, or Nikon Z-mount digital cameras with our Voigtländer mount lens adapters.
