A single-focus, wide-angle lens for use with K-mount digital SLR cameras, featuring latest lens coatings to further upgrade image quality
RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the HD PENTAX-FA 35mm F2. Despite its compact dimensions, this high-performance, wide-angle lens is designed to cover the full-frame image circle of PENTAX K-mount digital SLR cameras.
The development of this new lens was based on the smc PENTAX-FA35mm F2 AL — a very popular multi-purpose, wide-angle lens used on film-format SLR cameras — while conducting a thorough review of lens coatings.
The high-grade, multi-layer HD Coating has been applied to the optical elements to produce high-contrast images with edge-to-edge sharpness and free of flare and ghost images; the highly stain-repellent SP Coating has been applied to the front surface to improve the lens’s usability in outdoor locations. The exterior has been totally redesigned to match the design of latest PENTAX K-mount digital SLR models, while its compact, portable body makes it a perfect everyday-use lens.

Lens construction
Comparison of anti-backlight performance
Even under adverse conditions such as a strong light source in the image field, HD Coating effectively reduces the generation of ghost images, compared to conventional multi-layer coatings.
Comparison of transmissivity
Although both the old and new FA 35mm F2 lenses feature a simple lens construction, the HD PENTAX-FA 35mm F2 assures higher transmissivity as a whole, because its HD Coating-treated lens surfaces have superior anti-reflectance performance.
Main Features
HD Coating to enhance imaging power
After a thorough review of the lens coatings applied to the popular smc PENTAX-FA 35mm F2AL, PENTAX applied the latest HD Coating* to this lens. Compared to conventional multi-layer coatings, this high-performance, multi-layer coating reduces average reflectance and improves light transmittance to deliver extra-clear, high-contrast images free of flare and ghost images, even in demanding lighting conditions such as backlighting.
* HD stands for High Definition.
SP Coating to repel stains
Applied to the lens’s front surface, the SP (Super Protect) Coating is highly repellent to water and grease, making it easy to wipe off any stains. This frees the photographer from worries in outdoor photography.
New exterior design to match latest digital SLR models
While retaining the overall size of the original smc PENTAX-FA 35mm F2AL, this lens features a totally new exterior design, similar to that of the latest DA- and D FA-series lenses. This new appearance makes this single-focus lens a perfect partner for latest K-series digital SLR models. Since this lens retains the aperture ring, it also accommodates many of the functions provided by film-format SLR cameras and older K-mount digital SLR models, making it possible to enjoy photography using a greater range of cameras.
Easy-to-use standard lens
When mounted on a PENTAX digital SLR camera body, this lens provides a moderately wide 35mm angle of view with a full-frame model, or a standard 53.5mm angle of view with an APS-C-format model. Since it provides a natural perspective similar to that of the naked eye, it can be used as a multi-purpose standard lens in a wide range of applications, including snapshooting, scenic photography and portraiture. It also features a minimum focusing distance of 0.3 meters.
Compact, portable design
Weighing approximately 193 grams and measuring a mere 44.5 millimeters in length, this lens has been designed to be extremely compact and highly portable for carefree photography at any location and on every occasion.
Hybrid aspherical optical elements
The lens incorporates hybrid aspherical optical elements to effectively compensate for various aberrations. Thanks to these elements, it delivers extra-clear, high-contrast images from the minimum focusing distance to infinity, and edge-to-edge sharpness even at open aperture.
