The monochrome-sensor GR IV — dedicated black-and-white street compact.
The Ricoh GR IV Monochrome puts a dedicated black-and-white sensor in the GR IV body — no colour filter array, so every pixel records luminance for visibly finer detail and cleaner high ISO.
It keeps the GR IV package: 28mm-equivalent GR lens, 5-axis stabilisation, snap focus and pocket dimensions, with monochrome-specific picture controls in place of colour modes.
Its significance is bringing the dedicated-monochrome concept — long a Leica exclusive at ten times the price — to the street compact that black-and-white shooters already favoured.
Used examples are scarce and hold near-new pricing; confirm the seller's title really means the Monochrome sensor model rather than a black colour finish, and check the standard GR points — sensor dust and grip wear.
