Ricoh GR IIIx vs Ricoh GR IVx

9 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 IVx 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 IVx takes microSD. Budget for replacing your cards, not just adapting them.
• Both give the same field of view (40mm equivalent), so framing is not part of this decision.
• The Ricoh GR IVx 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 IVx reaches 204800 against 102400. Treat the headline number with scepticism — the top stop of any ISO range is a marketing figure.
• Only the Ricoh GR IVx records 4K. If video matters at all, this is the deciding row; if you only shoot stills, ignore it.
• The Ricoh GR IVx has 53GB of internal memory against 2GB — enough to shoot a full day with no card in the camera at all.
• 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.
• The Ricoh GR IVx is not released yet, and its specification is the one published at development announcement, which Ricoh says may change. You cannot buy one today.
