Optimized for super-high-resolution photography with high-megapixel digital SLRs, new Star-series lenses on display at Photo Plus Expo 2017 and Salon de la PHOTO 2017

 NEW YORK (Photo Plus Expo 2017, Booth #845), October 26, 2017 — Ricoh Imaging Americas Corporation today announced a new generation of high-performance Star-series lenses optimized for super high-resolution photography and high megapixel digital single-lens reflex (D-SLR) cameras.

Premium-quality Star-series lenses deliver the highest performance among the PENTAX K-mount interchangeable lens series, and have been highly regarded by PENTAX K-Mount users since the days of film. In addition to the initial design concepts of optimum image quality and large apertures for maximum light transmission, the series has embraced the additional concepts of exceptional toughness and outstanding operability, achieved through the development of a dustproof, weather-resistant construction. The resulting lenses provide superior dependability in a wide range of shooting conditions, and are the perfect companion to PENTAX SLR camera bodies.
