Cosina has launched the Voigtlander APO-Skopar 90mm f/2.8 for Nikon’s F-mount. Cosina says that the lens has been designed to bring the appearance of chromatic aberration to as close to zero as possible.
The APO-Skopar 90mm f/2.8 follows the Color-Skopar 28mm f/2.8 SL II S that Cosina launched in September, also for F-mount. It, like the 28mm, is a tribute to classic SLR lenses. The 90mm f/2.8, in particular, is described as a tribute to the lenses produced between 1965 and 1974 and features a silver rim (which Cosina is nicknamed Sakijiro among colelctors) or a black one (called Sakiguro). Both color options will be available when the lens comes to market.
The company says that the newly designed optical system uses “anomalous partially dispersed glass” in five out of the seven elements that are arranged in the seven-group construction. It has a 27.5-degree angle of view, a maximum magnification of 1:8.1, a nine-bladed aperture diaphragm, and a 52mm front element filter size. The lens features an aperture range of f/2.8 through f/22.
Cosina says that it uses an apochromat design that “makes the on-axis chromatic aberration of RGB, which constitutes the three primary colors of light, as close to zero as possible.”
Cosina adopted an all-metal helicoid unit that it processed and adjusted with what it describes as high precision and high-quality grease that produces appropriate torque and allows for smooth as well as precise and delicate focusing operation. Given that the lens is entirely manual focus, this kind of attention to detail in the focusing is likely to be appreciated. The company described similar attention to detail in its 28mm f/2.8.
Also like the 28mm f/2.8, the APO-Skopar 90mm f/2.8 is compatible with a variety of Nikon bodies, including Nikon’s that feature Ai-S with built-in CPU, but it also has an Ai coupler that Cosina says makes it possible to use with a variety of cameras from classic SLRs from the era the lens celebrates through the latest DSLRs.
The lens is designed specifically to be compact, and Cosina says that despite its high performance, the lens is just 40mm long.
Cosina says that the Voigtlander APO-Skopar 90mm f/2.8 will be available in November in both black and silver iterations for 68,000 yen, or about $596.
