Ricoh Imaging Americas Corporation today announced three HD PENTAX-FA Limited interchangeable lenses for use with PENTAX K-mount SLR cameras. Featuring the latest HD coating and a round-shaped diaphragm for a natural bokeh effect, these new prime lenses boast improved imaging performance to deliver sharp, distinctive images in combination with a K-mount camera body, while sporting an attractive exterior design.
The new members of the HD FA Limited Lens series are:
- HD PENTAX-FA 31mmF1.8 Limited: a lightweight, versatile wide-angle lens offering sharp imaging performance with natural perspective and high contrast.
- HD PENTAX-FA 43mmF1.9 Limited: an ultra-compact lens with exceptional high-contrast, high-resolution optics that is ideally suited for everyday use including indoor photography, traveling and hiking. This lens features a unique design element — A mount pointer made of a Shippoyaki (cloisonné) ware. This pointer allows the user to mount the lens to a camera body as effortlessly as other Limited Lens-series models.
- HD PENTAX-FA 77mmF1.8 Limited: a versatile lens specifically designed for portrait photography.
All three lenses are available black or silver and feature the distinguished qualities of the HD FA Limited Lens series including outstanding description of texture, fine reproduction of gradation in highlight areas, true reproduction of details, and natural reproduction of the bokeh effect. They deliver sharp, clear images free of flare and ghost images, even under demanding conditions like backlight. They also feature a completely round-shaped diaphragm to produce a natural, beautiful bokeh effect in the foreground and background.
The lenses have been treated with the PENTAX-original HD coating, which assures much higher light transmittance than conventional multi-layer coatings.
Lenses in the FA Limited Lens series are renowned for their high-quality details inside and out – from outstanding image rendition to durable aluminum bodies. These new lenses are specifically designed to ensure even better optical performance than the original Limited Lens series and are a prime example of PENTAX’s commitment to high-performance, high-quality products.

| Main features of the HD PENTAX-FA Limited Lenses (common to all three models) |
1. High-grade HD coating for exceptional image rendition
The three new lenses are treated with the PENTAX-original HD coating.* Compared with conventional multi-layer coatings, this high-grade coating assures higher light transmittance and lower reflectance to deliver sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight.
* HD stands for High Definition.
2. Round-shaped diaphragm for beautiful bokeh effect
All lenses feature a completely round-shaped diaphragm, which produces a natural, beautiful bokeh (defocus) effect in the images captured, while optimizing the imaging performance of the distinctive Limited lens-series optics contained within.
3. Acclaimed Limited Lens series quality for distinctive visual rendition and premium appearance
While inheriting the design concept of the Limited Lens series, these lenses were designed through a series of mechanical and numerical evaluations, as well as human assessment of test-shooting samples, to deliver an image rendition unmatched by other models. The barrel, hood and cap are all made of high-grade aluminum, meticulously machined for an attractive appearance and beautiful texture. The HD PENTAX-FA 43mm F1.9 Limited features a mount pointer made of a Shippoyaki (cloisonné) ware. This pointer allows the user to mount the lens to a camera body as effortlessly as other Limited Lens-series models.
4. Other features
- SP (Super Protect) coating is applied to the front surface of each lens to repel dust and stains.
- Black models are marked with a serial number starting with 0000001; silver models start with 1000001.
- The aperture ring has been retained so that the user can still use a variety of functions featured in K-mount film-format cameras.
