Ricoh have announced the development of a high performance prime lens, the HD PENTAX-D FA 85mm F1.4 SDM AW.

Ricoh Press Release

RICOH COMPANY, LTD. and RICOH IMAGING EUROPE, SAS. are pleased to announce the development of the new-generation high-performance Star-series lens, the HD PENTAX-D FA★85mmF1.4 SDM AW.

This product is the second “new generation D FA★” single focus lens. It follows the “HD PENTAX-D FA★ 50mm F1.4 SDM AW” which was the first fixed focal length lens from the "New Generation D FA ★" series. This series is known for outstanding image quality, with the lenses being defined by the following credentials:

• Best possible image quality with uniform sharpness from the centre to the edges of the image.

• Large aperture with particularly expressive images.

• High build quality, durable materials for longevity and easy handling

After the release of the PENTAX-D FA ★ 50mmm, it quickly became one of the most popular lenses for use with the PENTAX 35mm system. Since then, many PENTAX photographers have requested additional lenses to extend the range of prime lenses. Based on this, it is with great pleasure that we announce the development of another high performance lens in this series. With the HD PENTAX-D FA★85mmF1.4 SDM AW, we continue to pursue particularly high image quality without compromise.

Overview of the product under development

Model name: HD PENTAX-D FA85mmF1.4 SDM AW

Launch date: Scheduled for late 2020

  • By incorporating three Super ED (Extra-low Dispersion) glass optical elements, it effectively compensates chromatic aberrations and produces brilliant, high-contrast images even from open aperture.
  • Adopts one aspherical lens and achieves high delineation performance with good correction of spherical aberration, coma and field curvature.
  • High speed and smooth operation with newly developed SDM (Supersonic Direct-drive Motor) equipped with high torque ring type ultrasonic motor
  • Developing as an AW (All Weather model) this lens features a dependable dustproof, weather-resistant structure to prevent the intrusion of water and dust into the lens interior.

The designs and specifications are identical to those first announced publicly about the lens’s development, and are subject to change without notice.
