External Flash GF-2 for GR IV

Ricoh GF-2 External Flash for GR IV — Pocket Flash for the Pocket Camera

The gist: An ultra-compact rechargeable flash designed exclusively for the Ricoh GR IV — weighing just 19g and fitting in a pocket with the camera, it’s the natural fill-flash solution for street and travel shooters who live by the GR IV’s compact form factor.

• Genuinely pocketable: At 19g and 31mm tall, the GF-2 remains in your pocket even when attached to the GR IV — no belt clip, no bag required, no compromising the kit’s carry-anywhere DNA.
• ISO Auto Flash integration: When mounted on the GR IV, the camera’s ISO Auto Flash mode automatically adjusts guide number and ISO sensitivity to subject distance — hands-free exposure for fast street moments.
• USB-C rechargeable: Built-in lithium-ion battery charges via USB-C in about 2 hours — same cable as the GR IV, no extra charging brick needed for travel.
• ~270 flashes per charge: Full-power cycle delivers approximately 270 flashes with a 2-second recycle — sufficient for indoor markets, museum interiors, and low-light street scenes.

PetaPixel described the GF-2 as filling “the missing piece for street photographers” by adding intelligent auto flash without altering the GR IV’s compact shooting experience.

Best for: Ricoh GR IV owners who shoot street, travel documentary, or low-light scenes and want a fill-flash solution that doesn’t compromise the camera’s pocketable profile. Skip it if: you don’t own a GR IV — on other GR bodies it fires in full-discharge mode only until the October 2025 firmware update. Runs ~$120 — check the current price before buying.
