VOIGTLANDER APO-SKOPAR 90mm f2.8 VM Leica M-Mount BLACK Single Focus Lens manual

  
In addition to the high image quality achieved by the apochromatic design that minimizes axial chromatic aberration to near zero, this medium telephoto lens has a compact overall length of 60 mm (from the mount surface) thanks to a simple construction that extends the entire lens. The lightweight body weighs only 250g, which not only provides excellent portability, but also suppresses vignetting in the frame when using the optical rangefinder. The apochromatic design minimizes axial chromatic aberration of RGB, the three primary colors of light, to zero. The newly designed optical system consists of 7 elements in 7 groups, 5 of which are made of anomalous partial-dispersion glass. Despite its high performance, the lens is only 60mm in length (from the mount surface), and vignetting in the frame when using the rangefinder has been suppressed. 10-element aperture for "ball blur" expression.

The 10-element aperture has a special shape that is circular not only at the maximum aperture of F2.8, but also at F4 and F22. This allows photographers to take full advantage of the "ball blur" effect of point light sources and other objects. The included metal hood has a bayonet-type fitting and can be mounted in reverse when stored. It is convenient for carrying without compromising the compactness of the main body.

Manual Focusing for Reliable Focusing. The use of an all-metal helicoid unit machined and adjusted to a high degree of precision and high-quality grease that produces moderate torque enables focusing with a smooth operating feel. Subtle focusing adjustment is possible. The lens mount uses a VM mount compatible with the Leica M mount. The high-precision rangefinder-linked system allows for severe focusing near the maximum aperture. The camera has a generous image circle to accommodate a full-size 35mm-format camera. It also offers an extremely compact style compared to interchangeable lenses for SLR cameras. International Buyers - Please Note. Than you for your understanding.
