Ricoh GR IV HDF Review

The Ricoh GR IV HDF is a variant of the GR IV that swaps the standard optical low-pass filter for a built-in highlight diffusion filter, designed to soften highlights and emulate a more analog, film-like rendering. It retains the core strengths of the GR IV platform: a sharp 28mm f/2.8 lens, 25.7-megapixel APS-C sensor, excellent 6-stop in-body stabilization, and the pocketable form factor that has made the GR series a favorite among street photographers. The HDF filter gives images a distinctive glow in bright areas without sacrificing much detail or resolution, appealing to photographers who prioritize mood and character over clinical sharpness.

Reviewers appreciate the aesthetic the HDF brings, noting it delivers a more artistic, softer look that feels less digital and more like film, particularly in high-contrast scenes. The camera's street-shooting ergonomics, fast snap-focus modes, and generous 53GB of built-in storage earn consistent praise. However, the HDF effect is polarizing: it's a permanent hardware choice that can't be toggled off, and some find the diffusion too subtle to justify the premium over the standard GR IV. Video remains limited to 1080p, and the filter may not appeal to those who want maximum sharpness and flexibility in post. For photographers seeking a unique rendering and willing to commit to the look, the HDF offers a compelling twist on an already excellent compact.
