External Flash GF-2 for GR IV

Ricoh GF-2 External Flash for GR IV — Add Flash Capability Without Adding Bulk

The gist: Photographers and content creators who rely on the Ricoh GR IV for professional work can now add intelligent flash capability without outfitting the camera with a full-size speedlight — the GF-2 keeps the kit compact and shooting-ready.

• Automatic exposure integration: In ISO Auto Flash mode on the GR IV, the camera adjusts guide number and ISO to subject distance automatically — consistent, professional flash exposure without manual calculation mid-session.
• Minimal setup overhead: At 19g and 31mm tall, the GF-2 mounts and stays mounted without adding meaningful weight or drag to a working photographer’s kit — no speedlight to pack separately.
• USB-C charging: Recharges fully in about 2 hours via the same USB-C cable as the GR IV itself — one cable standard for the full kit.
• ~270 flashes per charge: Sufficient for headshot sessions, event coverage, and indoor product photography before needing a recharge.

PetaPixel called the GF-2 a “clever automatic mode” addition that finally rounds out the GR IV as a professional documentary and event camera without sacrificing the body’s defining compactness.

Best for: Documentary, event, and headshot photographers using the Ricoh GR IV as their primary professional body who need flash capability for indoor or low-light client work. Skip it if: you use a GR III or earlier model — full automatic integration requires a firmware update planned for October 2025. Runs ~$120 — check the current price before buying.
