The 90mm f/2.8 SLIIs Apo-Skopar from Voigtlander is a manual focus medium telephoto lens with a Nikon AIS F-mount and is optimized for full-frame image sensors. The newly designed optical system uses Abnormal Partial Dispersion glass for five out of seven elements in seven groups to make images rich, three dimensional in character, and extremely sharp. It has an apochromatic design that makes axial chromatic aberration as close to zero as possible. The manual focus lens is designed for use with SLR-type digital and film cameras and has a precision helicoid for smooth precise focusing action. The shortest shooting distance is 3', making it well suited to portraiture.
The SLIIs is compatible with Nikon AIS-type bodies with a built-in CPU. Equipped with an AI coupler, it can be used with a variety of bodies from classic film SLR cameras to the latest digital SLR cameras. The nine-blade diaphragm help provide a creamy bokeh suitable for portraiture. The focus and aperture rings are made entirely of metal and feature heavy finger indents with a precise machine knurling for a beautiful appearance reminiscent of vintage lenses, with functionality that enhances the feel of modern manual operation today.
