Ricoh's diffusion-filtered compact — the GR IIIx HDF with built-in highlight diffusion.
The Ricoh GR IIIx HDF is a special edition of the GR IIIx compact camera with a built-in Highlight Diffusion Filter. The HDF adds a subtle soft-focus glow effect to highlights — creating images with a distinctive dreamy quality while maintaining overall sharpness. The GR IIIx base provides a 40mm equivalent with APS-C sensor in a pocket-sized body.
Image quality is excellent from the 24.2MP APS-C sensor with the unique HDF rendering. The highlight diffusion filter adds a subtle glow around bright areas — creating a vintage, film-like aesthetic that cannot be perfectly replicated digitally. The base GR IIIx optics are sharp — the HDF adds character on top of the underlying quality. Sensor-shift SR.
