Overview
Ricoh Imaging is pleased to announce the new HD PENTAX-D FA* 50mm F1.4 SDM AW Lens. This is the first Star-series lens developed under Pentax's renewed performance evaluation criteria. This large-aperture, standard lens assures exceptional image quality with minimal aberrations.

The focal length of 50mm, standard among FF cameras, fully expresses the high resolution of the PENTAX FF series.

• High-performance, next-generation lens with large F1.4 maximum aperture
The HD PENTAX-D FA* 50mm F1.4 SDM AW was developed as part of the new next-generation Star series, delivering high image resolving power. It assures exceptional imaging performance from the center to the edges of the image field, even at open aperture, while providing a beautiful bokeh effect and outstanding image rendition at close ranges. Its large maximum aperture of F1.4 delivers bright, clear images in portraiture and indoor photography, making it versatile in capturing a wide array of subjects and scenes.

• State-of-the-art optical technology
The lens has been treated with PENTAX-developed Aero Bright Coating II – a lens-coating nanotechnology employing a super-low refractive film fabrication process. By coupling this advanced lens coating with the high-grade, multi-layer HD Coating, which reduces average reflectance in the visible ray spectrum to less than 50% of conventional multi-layer coatings, this lens effectively reduces flare and ghost images to a minimum even in demanding lighting conditions such as backlighting.

• Dustproof, weather-resistant construction
Developed as an All Weather (AW) model, this lens features a dependable dustproof, weather-resistant structure with eight special seals to prevent the intrusion of water and dust in the lens interior. When paired with a PENTAX weather-resistant digital SLR Camera body, it forms a durable, reliable digital imaging system that performs superbly in demanding outdoor shooting settings.

• Newly developed ring-type ultrasonic motor SDM
The lens features a newly developed ring-type ultrasonic motor SDM, which generates almost twice the torque of a conventional lens-driving motor. Thanks to this enormous driving power, the lens assures smooth, high-speed shifting of the heavy, multi-element rear lens group during focusing operation.

• Rounded Diaphragm
Nine-blade rounded diaphragm to produce a natural bokeh (defocus) effect at up to F2.8 aperture setting, while minimizing the streaking effect of point light sources.

• Quick-Shift Focus System
Allows for instant switching from auto-focus to manual-focus operation.

• SP Coating
SP (Super Protect) Coating applied to the front surface of the lens to effectively repel water and grease.
