Ricoh GR IIIx vs Ricoh GR IV

10 of 14 specifications differ. Everything else is identical on both manufacturer spec sheets.

What the differences mean

• Batteries do not carry over. The Ricoh GR IIIx takes a DB-110; the Ricoh GR IV takes a DB-120. Any spares you own for one are useless with the other.
• Memory cards do not carry over. The Ricoh GR IIIx takes full-size SD; the Ricoh GR IV takes microSD. Budget for replacing your cards, not just adapting them.
• This is mainly a lens decision, not a camera decision. The Ricoh GR IV is the wider of the two; the Ricoh GR IIIx is tighter and sits closer to how people naturally see. Neither zooms — you pick one focal length and live with it.
• The Ricoh GR IV has the more capable stabiliser (5-axis vs 3-axis), which matters most for handheld shots in low light.
• Top ISO differs: the Ricoh GR IV reaches 204800 against 102400. Treat the headline number with scepticism — the top stop of any ISO range is a marketing figure.
• The Ricoh GR IV has 53GB of internal memory against 2GB — enough to shoot a full day with no card in the camera at all.
• Crop steps differ (Ricoh GR IIIx: OFF / 50mm / 71mm; Ricoh GR IV: OFF / 35mm / 50mm). These are sensor crops, not a zoom — you lose pixels in exchange for tighter framing.
• Close-focus differs (Ricoh GR IIIx: Normal 0.2m-inf; macro 0.12-0.24m; Ricoh GR IV: Normal 0.1m-inf; macro 0.06-0.15m). The wider body focuses nearer, which is the usual trade for a shorter lens.
• The Ricoh GR IIIx is discontinued — Ricoh gives 2026-10 as the end of production. Expect stock to thin and used prices to move unpredictably.
