Cosina has announced two Voigtländer-branded lenses which it will be making available for Nikon and Pentax DSLR mounts. The Voigtländer Ultron 40mm F2 SLII Aspherical - to give its full title - is a 'Pancake' type lens protruding a mere 24.5mm from the lens mount. The optical design comprises six elements in five groups including a double-aspheric element and high-refraction glass. The Nokton 58mm F1.4 SLII meanwhile is based on a Topcor design with seven elements in six groups and when mounted on an APS-C camera replicates the angle of view of an 85mm making it an ideal choice for portrait photography. The Nikon-mount examples are Ai-s specification and feature a CPU to allow metering on modern bodies whilst the Pentax mounts are KA compatible. Only Japanese pricing and availability has been announced thus far with both lenses expected to retail for around ¥50,000 when they arrive on shelves over the next two months.
