The Ricoh GR1s of 1998 is the mid-generation of the legendary GR1 film compacts: the 28mm f/2.8 GR lens with an added filter thread adapter option and an improved viewfinder with more visible framelines.
It pairs the seven-element 28mm f/2.8 GR lens — sharp enough that Ricoh later sold it as a Leica screw-mount lens — with aperture-priority or program exposure, snap focus, and a magnesium body slimmer than almost any camera before or since.
Its significance is as the affordable middle child between the GR1 and the GR1v: most of the v's capability at a lower collector premium, with the same lens that defines the series' reputation.
Used GR1s bodies hinge on the LCD: the top display fades and is effectively unrepairable, so price accordingly. Check the film advance sounds healthy and the lens extends cleanly — electronics failures are terminal on these.
