Product Features in Detail Super-compact designExclusively designed for use with the RICOH GR IV premium compact camera, the GF-2 features a super-compact body for outstanding portabilitysmall enough to fit in a pocket, even when attached to the GR IV. Simple, effortless operationWhen mounted on the RICOH GR IV and the camera is 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 subjects distance. This mode enhances the GR IVs 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. This firmware designed to allow a GR-III-series camera to automatically adjust the discharge level according to its focusing status is currently under development. The firmware is scheduled to be released in October 2025. Built-in lithium-ion batteryThe GF-2 is equipped with a rechargeable lithium-ion battery, which can be charged via a USB Type-C terminal. Even when the cameras battery runs low, this built-in battery stabilizes the flash discharge level.
