Pentax K-3 Mark III Monochrome Camera Body Summary
Pentax has utilised a specific monochrome sensor, which solely records black and white data for the Pentax K-3 Mark III Monochrome DSLR camera, enabling you to capture beautiful images rich in tonal gradation. It has been designed for photographers who pursue black and white photography and compose their images solely with light and shadow, in order to express a unique view of the world.
Every pixel in the high resolution 25.73 megapixel APS-C-format CMOS sensor detects brightness data coming through the lens and converts this in order to compose a photograph. Pentax continued the monochrome theme across the K-3 Mark III Monochrome camera body design, with white backlight illumination on the LCD data panel and grey toned buttons and dials. The camera also features three Custom Image modes designed exclusively for the monochrome sensor, which provide adjustment of tone, key, contrast and sharpness, for fine tuning of the results. Photographers also gain an advanced SR (Shake Reduction) mechanism found in certain Pentax DSLR cameras, which helps to capture blur-free images while optimising the distinctive expression of each Pentax K mount lens.

Pentax K-3 Mark III Monochrome in More Detail
Monochrome image sensor
The Pentax K-3 Mark III Monochrome features a Monochrome APS-C-format CMOS image sensor with approx. 25.73 effective megapixels specifically designed to capture only black and white images. By designing the camera solely for the purpose of monochrome photography, each pixel detects brightness data of the light coming through the lens. The obtained data is then directly converted to compose an image. This enables the photographer to create extra-fine monochromatic expression in an image high in resolution and rich in gradation.
Capture pure images through only light and shadow
Monochrome (or black-and-white) photography is the origin of photographic art. Without colour data, monochrome can more clearly depict the form and texture of a subject using light, shadow and the in-between gradations. This means that the photographer can create images that are more impressive and persuasive. By designing the camera solely for the purpose of monochrome photography, each pixel detects brightness data of the light coming through the lens. The obtained data is then directly converted to compose an image.
Typical colour image sensors are designed to receive light passing through red (R), green (G) and blue (B) colour filters, so each pixel detects only one colour data component. To compose a monochrome image, colour sensors must convert colour data into monochromatic data by interpolating the obtained colour data while using adjacent areas of the image field as a reference.
Since a monochrome-specific image sensor can faithfully reflect the brightness data obtained by each pixel in the image — without the interpolation process — the photographer can create extra-fine monochromatic expression, in an image high in resolution and rich in gradation.
Image quality made exclusively for black and white photography
Image quality has been re-evaluated and redesigned to optimise the imaging characteristics of the monochrome-specific image sensor. Unlike a colour sensor that requires the interpolation process, each pixel of the monochrome-specific image sensor corresponds precisely to each pixel in the resulting image. The result is minimal deterioration of the data obtained, and optimal visual expression. To optimise these advantages, the imaging process has been completely restructured to assure 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.
Monochrome-specific Custom Image modes
The camera features three Custom Image modes exclusively designed for the monochrome-specific image sensor: Standard, Hard and Soft. Each mode provides minute adjustment of parameters such as tone, key, contrast, and sharpness. This allows the photographer to personalise images for the desired finishing touch.
Exterior body design reflects the monochrome concept
The concept of monochrome photography is evident throughout the Pentax K-3 Mark III Monochrome camera body, from the white backlight illumination on the LCD data panel positioned on its upper panel, to the Monochrome lettering printed on the upper-left shoulder of the back panel. The camera’s User Interface menu features a black-and-white colour scheme as default, while the icons printed on buttons and switches across the camera’s exterior are finished in three shades of grey.
Other noteworthy features
- Minimum ISO setting at 200 – Since the monochrome-specific image sensor is free of the colour filters that cause a loss of light, it can take in more light. This allows the camera’s minimum ISO to be set at 200.
- Fx button – Unlike full-colour photography, in which colour reproduction varies depending on the light source (or colour temperature), monochrome photography doesn't require white balance control. In the Pentax K-3 Mark III Monochrome, the white balance button of the Pentax K-3 Mark III is replaced with the Fx (function) button.
- In-body 5-axis shake reduction mechanism – The Pentax K-3 Mark III Monochrome incorporates an advanced SR (Shake Reduction) mechanism, which lets the photographer use all types of lenses, whether the latest or vintage and to capture sharp, blur-free images while optimising the distinctive visual expression of each lens.
Huge range of lenses and accessories
Joining the Pentax K mount system provides access to a huge variety of new K mount lenses as well as used and vintage legacy lenses, which are fully compatible with the camera.
