Exclusively designed for use with the RICOH GR IV premium compact camera,
the GF-2 features a super-compact body for outstanding portability—small
enough to fit in a pocket, even when attached to the GR IV. When 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 subject’s distance. This mode enhances the GR IV’s snapshot operations in casual flash photography.
