The GF-2 External Flash is a compact, slim flash designed specifically for the GR IV. It features a super-compact body for outstanding portability, small enough to carry in a pocket while attached to the GR IV camera. When the GR IV is set 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.
