External Flash RICOH GF-2
Super-compact flash, exclusively designed for use
with the RICOH GR IV
TOKYO, August 21, 2025 -- RICOH IMAGING COMPANY, LTD. is pleased to announce the release of the External Flash RICOH GF-2. With a maximum guide number of 3 (at ISO 100/m), this super-compact, ultra-lightweight accessory flash unit provides an auto flash function when mounted on the RICOH GR IV compact digital camera body.
Main features
1. Super-compact design
Exclusively designed for use with the RICOH GR IV high-end digital compact camera, the GF-2 features a super-compact body for outstanding portability, making it perfect for carrying in a pocket without the need to remove it from the camera body.
2. Simple, effortless operations
When mounted on the RICOH GR IV and the camera set to the ISO Auto Flash mode, the GF-2 allows the camera to automatically adjust its guide-number and ISO sensitivity settings according to the subject's distance. This flash mode enhances the GR IV's snapshot operations in casual flash photography.*
* When mounted on a RICOH GR-series model other than the GR IV, the GF-2 only operates in the full-discharge mode, because the alignment of flash contacts (except for the X-sync contact) differs from that of the GR IV.
The firmware designed to allow a GR-III-series camera to automatically adjust the exposure level according to its focusing status is currently under development. This firmware is scheduled to be released in October 2025.
3. Built-in lithium-ion battery
The GF-2 incorporates a rechargeable lithium-ion battery, which can be charged via an USB Type-C terminal. Even when the camera's battery runs low, this built-in battery stabilizes the flash discharge level.
