Ricoh Flash GF-2 – Compact, dedicated rechargeable flash for RICOH GR IV

The Ricoh Flash GF-2 is a compact, purpose-built flash designed specifically for the RICOH GR IV. It slips into a pocket, stays on the camera without getting in the way, and provides clean, controlled light for street and travel photography. Because it is compact and independently powered, you stay ready to capture fast, candid moments without compromising handling or reliability.

Built for street and travel shooting

The GF-2 focuses on simplicity and portability. It mounts easily on the GR IV and keeps a low profile, making it a practical, always-with-you flash solution. Photographers who prefer a minimalist setup will find it fast to handle and predictable in output, so you can concentrate on composition and timing rather than fiddling with flash settings.

Automatic flash control with GR IV

When mounted on the RICOH GR IV and the camera is set to ISO Auto Flash, the GF-2 enables automatic flash control. This pairing adjusts both the effective guide number and the camera’s ISO sensitivity to match subject distance. As a result, it helps keep exposures consistent as scenes change, eliminating the need to dig through menus or guess power levels.

Independent power and stable performance

The GF-2 runs on a dedicated, rechargeable lithium-ion battery and charges via a USB Type-C terminal. Because the flash has its own power source, recycle performance remains stable even if the camera battery is running low. This design suits longer shoots and fast sequences where consistent flash availability matters.

FAQ

Question: Is the GF-2 compatible with cameras other than the RICOH GR IV?
Answer: The GF-2 is exclusively designed for the RICOH GR IV. When attached to other GR-series cameras, it will operate only in full-discharge mode due to different contact alignment, with the exception of the X-sync contact.

Question: Will GR III-series cameras gain automatic exposure adjustment with this flash?
Answer: Firmware to enable GR III-series cameras to automatically adjust exposure level based on focusing status is under development and is scheduled for release in October 2025. Until that firmware is released, automatic pairing behavior described for the GR IV will not be available on GR III-series models.

Question: How long does the battery last and how quickly does the flash recycle?
Answer: On a full charge, the GF-2 delivers approximately 270 flashes and has an approximate recycle time of 2 seconds. It charges via USB Type-C from its dedicated lithium-ion battery.

Question: Can I use the GF-2 with a wide conversion lens on my GR camera?
Answer: The flash’s coverage is set to an 18 mm focal length and a wide conversion lens is not supported. This means the GF-2 is intended for use without a wide conversion lens attached.
