General description
The RICOH GR IV HDF is based on the GR IV platform and adds a built-in Highlight Diffusion Filter (HDF). This filter diffuses highlights and reduces apparent contrast in those areas, allowing you to switch between a sharp and a softer rendering directly from the camera.
It retains the approximately 25.74 MP APS-C sensor, the 28 mm equivalent fixed focal length, 5-axis stabilization, and 53 GB of internal memory from the GR IV platform.
