Ricoh has released the Pentax K-3 III Monochrome, a DSLR designed to shoot exclusively in black and white. It joins other monochromatic cameras like the Leica M Monochrom (Typ 246)Leica M10 Monochrom and Leica Q2 Monochrom in a market that has been previously dominated by Leica.

Based on the Pentax K-3 III, the flagship model of Pentax’s APS-C-format series, this camera features a monochrome-specific 25.7MP image sensor, an LCD data panel with white backlight illumination, and a menu screen with a black and white visual scheme. It also looks the part of a monochrome camera, with the icons printed on the camera’s buttons and switches finished in shades of grey rather than the usual colour paint.

The Pentax K-3 III Monochrome has three exclusive Custom Image modes for black and white photographers, including modes for both high-contrast and low-contrast photography, which can then be customised by adjusting settings like tone, key, contrast and sharpness. Additionally, it can shoot black and white video at up to 4K/30p.

Pentax’s new monochromatic camera will be available to buy in late April 2023 through Ricoh and authorised retailers for a price of $2,199.95 / £2,249 (body-only).

From Ricoh:

PARSIPPANY, NJ, April 12, 2023 — Ricoh Imaging Americas Corporation today announced the PENTAX K-3 Mark III Monochrome camera, exclusively designed to capture black-and-white images. The only monochrome-specific digital SLR camera currently on the market, it captures high-resolution images rich in gradation, enabling users to express a distinct view of the color-rich world in high-quality black-and-white images.

“The concept of a monochrome-specific digital SLR camera attracted a great deal of attention and interest from photographers who participated in an online fan event held in November 2021,” said Ken Curry, president, Ricoh Imaging Americas. “PENTAX has since conducted extensive research on the development of a commercial product based on this concept and we’re excited to announce it today.”

The new model’s design is based on the PENTAX K-3 Mark III — the flagship model of PENTAX’s APS-C-format series that integrates remarkable imaging performance and a host of advanced features in a compact, durable body — while totally redesigning and optimizing the imaging characteristics by adding a new, monochrome-specific image sensor with approximately 25.73 effective megapixels. A typical color image sensor composes a black-and-white image by converting the color data to monochrome. This new custom sensor does not have to convert the any data because it can reflect the brightness obtained by each pixel in the image, thus producing extra-fine sharpness in images that only the monochrome-specific sensor can deliver.

The PENTAX K-3 Mark III Monochrome features three Custom Image modes exclusively designed for black-and-white photography to provide distinctive finishing touches. In addition to Standard mode, it offers Hard mode to produce high-contrast images and Soft mode to create high-key, low- contrast images. Each mode allows minute adjustment of parameters such as tone, key, contrast and sharpness so that users can personalize their images with the desired finishing touch.

The exterior design of the camera has also been customized to reflect its monochrome capabilities. Design features include white backlight illumination on the LCD data panel, “Monochrome” lettering printed on the upper-left shoulder of the back panel, a menu screen featuring a black-and-white visual scheme as default, and icons printed on buttons and switches across the camera’s exterior finished in three shades of gray.

Main features of the PENTAX K-3 Mark III Monochrome

Monochrome-specific CMOS image sensor

To optimize the quality of monochromatic images, the camera incorporates a monochrome- specific, APS-C-format CMOS image sensor free of an AA (anti-aliasing) filter with approximately 25.73 effective megapixels. Typical color image sensors are designed to receive light passing through red (R), green (G) and blue (B) color filters, so each pixel detects only one color-data component. To compose a monochrome image, color sensors must convert color data into monochromatic data by interpolating the color data they collect. The new monochrome-specific image sensor, however, can faithfully reflect the brightness data obtained by each pixel in the image — without the interpolation process — to produce extra-fine monochromatic expression, in images high in resolution and rich in gradation.

Image quality exclusively designed for monochrome photography

The image quality produced by the original PENTAX K-3 Mark III was thoroughly re- evaluated and totally redesigned to optimize the imaging characteristics of the new monochrome-specific image sensor. The result is highly sensitive expression with a natural bokeh (defocus) effect, rich gradation and extra-fine sharpness — an image only the monochrome-specific image sensor can deliver.

A selection of monochrome-specific finishing touches

The PENTAX K-3 Mark III Monochrome provides three Custom Image modes exclusively designed for monochrome photography to provide distinctive finishing touches. In addition to Standard mode, it also provides Hard mode to produce high-contrast images, and Soft mode to create high-key, low-contrast images. Each mode provides minute adjustment of parameters such as tone, key, contrast and sharpness. This allows the photographer to personalize their images with the desired finishing touch.

Exterior design reflecting the monochrome photography concept

The PENTAX K-3 Mark III Monochrome provides white backlight illumination on the LCD data panel positioned on its upper panel, while featuring “Monochrome” lettering printed on the upper-left shoulder of the back panel. Its menu screen features a black-and-white visual scheme as default, while the SR (Shake Reduction) badge is finished in silver. The icons printed on buttons and switches across the camera’s exterior are finished in three shades of gray to assist the users with their camera operation. All in all, the concept of monochrome photography is evident throughout the camera body.
