This 35mm f/2 APO-LANTHAR Aspherical from Voigtlander is an optically refined, apochromatic wide-angle Leica M-mount prime with a 35mm focal length. When used with APS-C format cameras, it can provide a 52.5mm equivalent focal length. Its bright f/2 maximum aperture is beneficial for working in dimmer conditions and also affords greater control over focus position for selective focus applications. Thanks to its apochromat design and incorporation of anomalous partial dispersion and aspherical elements, a range of aberrations are markedly eliminated or suppressed to achieve imagery of high resolution, sharpness, clarity, colour fidelity, and contrast reproducibility. The lens sports a manual focus design, along with a high precision helicoid, to provide refined focusing control and enable smooth operation. Equipped with a high-precision rangefinder interlocking mechanism, severe focusing near the maximum aperture is enabled. With its 12 diaphragm blades, the lens can create pleasing bokeh when working with shallow depth of field techniques. A rear and front lens caps are supplied along with the lens.
