A black-and-white-only GR IV: the 25.7MP APS-C sensor has no colour filter array, so every pixel records luminance and the native ISO range climbs to 409,600. The GR IV's switchable ND filter makes way for a built-in red filter that darkens blue skies, and the tone presets are rebuilt for monochrome. Otherwise it is the standard GR IV: the same 28mm-equivalent f/2.8 lens, 6-stop IBIS, 262g body and no built-in viewfinder.
