Pentax's black-and-white DSLR — the K-3 Mark III Monochrome, APS-C mono sensor, K mount, in-body SR, 2023.

The Pentax K-3 Mark III Monochrome was released in 2023 as a black-and-white-only version of the flagship K-3 Mark III, at the top of Pentax's APS-C K-series digital SLR line. Its sensor is built without a colour filter array, so it captures only monochrome images, making it a specialised body for photographers committed to black-and-white work.

This is an APS-C digital SLR on the Pentax K mount with a dedicated monochrome CMOS sensor that records black-and-white only. It has an optical pentaprism viewfinder with high magnification and includes sensor-shift in-body Shake Reduction that works with any mounted lens. The body is weather-sealed and records video. Because the sensor omits the colour filter array, it cannot produce colour images.

The monochrome-only sensor gives tonal rendering aimed at photographers who work exclusively in black and white, suiting documentary, street and considered professional use. The full K-mount compatibility lets it use the entire Pentax lens range including older manual glass with stabilisation, and the flagship build and finder support deliberate, viewfinder-led shooting.

On the used market, check the shutter operation and actuation count against its rated life, listen for normal versus faulty Shake Reduction rattle, and inspect the sensor for dust and marks. Test the rear LCD for dead or stuck pixels, check the card and battery door latches and the weather-seal rubber, and confirm the D-LI90 battery holds charge; aftermarket cells are available. Check the grip rubber, and note that as a monochrome-only body it suits buyers who specifically want black-and-white capture; the K mount carries broad compatibility with older Pentax lenses.
