HD PENTAX-D FA★ 85mm F1.4 ED SDM AW development update!

RICOH IMAGING is pleased to announce the development of another lens from the D FA★ generation from the PENTAX “Star Series”.

The presentation of a prototype of the new HD PENTAX-D FA★ 85mm F1.4 ED SDM AW lens was originally planned for this year’s CP +, which was to take place in Yokohama at the end of February. Since the fair was canceled due to the corona virus (COVID-19), the development of this new lens is now announced in this way.

With the HD PENTAX-D FA 50mm F1.4 SDM AW, RICOH IMAGING presented the first lens with a fixed focal length of the new D FA generation of the PENTAX “Star Series” in summer 2018. The “Star series” stands for the highest quality standard of the PENTAX lens series. The D FA series is characterized by the following parameters:

・ Best possible image quality with uniform sharpness from the center to the edges
・ Large aperture with a particularly expressive image effect
・ High quality workmanship and materials with high robustness and easy handling

The D FA★ 50mm quickly became one of the most popular lenses for the PENTAX 35mm system, so that more and more PENTAX photographers want to expand this series of top lenses with a fixed focal length.

With the HD PENTAX-D FA★ 85mm F1.4 ED SDM AW, another lens from this series of high-performance lenses is now under development and the waiting will soon come to an end.

In line with the product strategy “particularly high image quality without compromise”, this new lens is characterized by the following features:

・ Three optical Super ED glass elements (extra-low dispersion) effectively compensate for chromatic aberrations and produce brilliant, high-contrast images even when the aperture is open.
・ An aspherical lens ensures high imaging performance with good correction of spherical aberration, coma and field curvature.
・ The high-torque ultrasonic ring motor with Supersonic direct drive (SDM) enables a high focusing speed and smooth operation.
・ The lens, developed as an AW model (All Weather), has a reliable weatherproof construction that prevents water and dust from entering the lens interior.

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