Product Description

A Faster GR with a Dreamlike Touch
The Ricoh GR IV HDF reimagines the “ultimate snap shooter” with a subtle, expressive twist. This special edition of Ricoh’s iconic compact camera introduces a built-in Highlight Diffusion Filter (HDF), designed to render highlights with a soft, blurred glow for a dreamy, cinematic, and nostalgic look straight out of the camera.

Replacing the ND filter from the standard model, the GR IV HDF retains everything photographers love about the series — including its 25.7MP BSI CMOS sensor, 28mm-equivalent f/2.8 lens, fast autofocus, advanced Shake Reduction, and seamless GR WORLD app connectivity — but adds a new layer of creative expression for visual storytellers.

HDF Distinctions

• The built-in Highlight Diffusion Filter produces gentle, misty highlights for a filmic, ethereal feel.

• Easily toggle the HDF on or off with a single press of the rear Fn button, now labeled “HDF.” The function can also be reassigned to other controls for flexibility.

• The camera features a distinct silver shutter release button, setting it apart visually from other GR IV models.
