AT A GLANCEBuilt-in RICOH-original HDF (Highlight Diffusion Filter), to create softer, more expressive images
The GR IV HDF incorporates the RICOH-original HDF (Highlight Diffusion Filter), which is designed to emphasize highlights and produce mellow, soft images. Developed by taking advantage of the advanced inkjet technology RICOH has cultivated over the years, this special-effect filter diffuses highlight areas and creates a blurred effect along the image’s edges, making it possible to capture nostalgic images resembling those captured in film photography or movies. HDF can be instantly switched on and off with a single action, allowing the user effortlessly to alternate between two completely different visual expressions — clear, sharply focused images representative of the RICOH GR series, and softer light, more expressive images captured by the HDF — depending on the subject or creative intention.High-speed electronic shutter with a top speed of 1/16,000 second for shooting at
extremely bright locations
In addition to a conventional mechanical shutter unit, the GR IV HDF also features an electronically controlled shutter mechanism,* which allows the user to intentionally raise the shutter speed up to 1/16,000 second, making it possible to capture images at extremely bright locations while still setting a larger aperture.HDF default setting for Fn Button and update to Shutter-release button colour
The default setting of the Fn (Function) button has been changed to the HDF ON/OFF switching function**, allowing the user to quickly engage the HDF (Highlight Diffusion Filter) with the press of the button.
