The RICOH GR IV HDF's built-in HDF (Highlight Diffusion Filter) introduces a new level of expressive power to street photography, allowing for softer, more personal interpretations of light directly during the shot. Instantly activated or deactivated, the HDF allows for two distinct visual approaches: the clean, sharp, and high-contrast aesthetic that has made the GR series iconic; or a more delicate, diffused rendering, capable of softening bright areas and conveying a more evocative, cinematic atmosphere. This versatility makes the GR IV HDF an ideal tool for those who embrace street photography as an expressive language, where the moment is not just to be captured, but also interpreted. The HDF filter targets the brightest areas of the image, creating a smoother transition between light and shadow and adding depth and character to the shot, without compromising the speed and responsiveness that distinguish the GR series. --- The Ricoh GR IV is a premium compact camera designed to deliver the highest image quality in a pocket-sized body, ideal for street, travel, and reportage photography. It features a 1/1.7" 10-megapixel CMOS sensor paired with the GR Engine IV processor, delivering sharp, detailed images with excellent tonal rendition. The 28mm f/1.9 GR Lens (full-frame equivalent) is one of the camera's strengths: bright, fast, and perfectly optically corrected, it delivers images with natural contrast and stunning three-dimensional rendering. The built-in SR (Shake Reduction) optical image stabilization system allows for handheld shooting even in difficult lighting conditions, while the hybrid AF module offers fast and precise focusing with continuous tracking. The GR IV features a 3" LCD display with VGA resolution, customizable menus, and direct controls that keep the shooting experience intuitive and immediate. The electronic shutter reaches speeds of up to 1/2000 of a second, allowing you to work wide open even in bright light. With its lightweight yet robust magnesium alloy body and understated, professional design, the Ricoh GR IV stands out for its ability to combine excellent photographic performance with absolute portability, making it an iconic tool for those who love pure, spontaneous photography.
