Ricoh has officially introduced the Ricoh GR IV HDF, a new premium compact camera built on the foundation of the GR IV but enhanced with a unique Highlight Diffusion Filter (HDF). This built‑in optical filter allows photographers to instantly switch between the classic GR look—crisp, sharp, high‑contrast—and a softer, more cinematic rendering with diffused highlights. For street photographers and creators who want expressive versatility without carrying extra gear, the GR IV HDF marks one of the most interesting updates in the GR lineup.
Key Features
- Built‑in Highlight Diffusion Filter (HDF): Softens highlights, adds glow, and creates a nostalgic, film‑like look.
- Instant HDF toggle: Switch between standard GR sharpness and diffused rendering with a single action.
- 1/16,000s electronic shutter: Enables wide‑aperture shooting in bright environments without overexposure.
- Updated shutter button: New grayish‑silver finish symbolizes the camera’s dual‑expression capability.
- Fn button defaults to HDF control: Quick access to creative switching (customizable).
- Same core performance as GR IV: Retains the proven image quality, portability, and fast operation of the base model.
What’s New With the Highlight Diffusion Filter?
The Ricoh GR IV HDF’s standout feature is its integrated Highlight Diffusion Filter, developed using Ricoh’s inkjet‑technology expertise. The filter diffuses bright areas and gently blurs edges, producing a mellow, cinematic look reminiscent of analog film or vintage cinema lenses. Unlike external diffusion filters, HDF is built into the camera and can be activated instantly, making it ideal for fast‑moving street photography where lighting and mood shift rapidly.
This dual‑look capability effectively gives photographers two cameras in one: a classic GR for sharp documentary work, and a soft‑rendering compact for atmospheric storytelling.
Who Is It For?
The Ricoh GR IV HDF is designed for:
- Street photographers who want expressive flexibility without carrying extra filters.
- Travel shooters looking for a compact camera capable of both crisp and cinematic looks.
- Content creators who want a unique, film‑inspired aesthetic straight out of camera.
- GR loyalists interested in a new creative tool that expands the series’ visual possibilities.
Considerations & Limitations
- The HDF effect cannot be fine‑tuned—it’s either on or off.
- No built‑in ND filter, unlike some previous GR models.
- Price is higher than the standard GR IV, reflecting the added optical technology.
- Sensor and core imaging pipeline remain unchanged from the GR IV.
Price & Availability
Ricoh states that the GR IV HDF will be available in late January through Ricoh Imaging’s online store and authorized retailers. The camera will also be showcased at GR SPACE locations in Tokyo, Shanghai, Beijing, and Brisbane starting December 17, giving fans an early chance to try the new diffusion system.
Final Thoughts
The Ricoh GR IV HDF brings a meaningful creative twist to one of the most respected compact cameras on the market. By integrating a Highlight Diffusion Filter directly into the body and allowing instant switching, Ricoh has created a tool that appeals to both purists and experimental shooters. For photographers who want a compact camera capable of delivering both razor‑sharp GR rendering and soft, cinematic glow, the GR IV HDF stands out as one of the most intriguing releases of the year.
