Ricoh updates Pentax 31mm F1.8, 43mm F1.9 and 77mm F1.8 Limited lenses

Ricoh has announced the release of three HD Pentax-FA Limited lenses for K-mount DSLR cameras: the HD Pentax-FA 31mm F1.8 Limited, HD Pentax-FA 43mm F1.9 Limited and HD Pentax-FA 77mm F1.8 Limited.

These three lenses feature the same optical construction as their respective non-HD predecessors, while bringing a number of new and improved features. The first notable change is the addition of Ricoh’s High-Definition (HD) coating on the lenses. Ricoh says the HD 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.’

Ricoh has also updated the aperture diaphragm in each of the lenses to be ‘completely round-shaped’ for smoother bokeh. Other improvements include a retained aperture ring for maximum functionality with Pentax K-mount film cameras and a Super Protect (SP) coating applied to the front elements of each of the lenses to help repel dirt and dust.

Ricoh says the black models will be marked with a serial number starting at 0000001 while the silver models will start with 1000001.

The HD Pentax-FA 31mm F1.8 Limited lens, HD Pentax-FA 43mm F1.9 Limited lens and HD Pentax-FA 77mm F1.8 Limited lens will all be available at Ricoh’s online shop and at authorized Ricoh retailers in April 2021 for $1,050, $600 and $800, respectively.

Ricoh announces three HD PENTAX-FA Limited interchangeable lenses for K-mount SLR cameras

New prime lenses feature round-shaped diaphragm, latest HD coating for outstanding image quality

PARSIPPANY, NJ, February 24, 2021 — 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 31mm F1.8 Limited: a lightweight, versatile wide-angle lens offering sharp imaging performance with natural perspective and high contrast.

• HD PENTAX-FA 43mm F1.9 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 77mm F1.8 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.
