The 2005 original GR Digital — 28mm f/2.4 lens, the small-sensor GR that started the line.
The 2005 Ricoh GR Digital brought the revered GR1 film compact formula into the digital era: a pocketable magnesium body with a fixed 28mm-equivalent f/2.4 GR lens.
It pairs an 8.1MP 1/1.8-inch CCD with the sharp 5.9mm GR lens, full manual control via the trademark front dial, RAW capture, and an optional optical viewfinder on the hot shoe.
Its significance is founding the GR Digital line: it kept serious street photographers in the Ricoh camp through the digital transition and its control layout survives unchanged on today's GR III.
Used examples are CCD-era collectibles; check the retracting lens mechanism for dust and error messages, LCD condition, and battery age. Sellers often title it just 'GR Digital' — the 8.1MP spec separates it from the 10MP II that followed.
