Description Specifications

Introducing the Ricoh GR IV - HDF Edition
The new GR IV HDF builds on the acclaimed performance of the RICOH GR IV and adds a built-in Highlight Diffusion Filter that can be activated instantly with a single press. Offering two distinct visual styles in one compact, pocketable camera, it allows
photographers to move effortlessly between sharp, high-contrast images and a softer, more atmospheric look with gently diffused highlights.

Designed to expand creative possibilities in everyday photography, the GR IV HDF makes versatile expression simple and
accessible.

• Highlight Diffusion Filter (HDF): Replaces the built-in ND filter to gently diffuse highlights, creating a softer, more expressive
look.
• An electronic shutter allows shooting wide open with HDF engaged, even in very bright conditions.
• The HDF can be toggled on or off using a single button—the rear Fn button is labelled “HDF” and is set to control the filter by
default. This button can be reassigned, and the HDF function can also be programmed to other controls if preferred.

HDF filter, A new visual signature

Exclusive to the GR IV HDF, the Highlight Diffusion Filter (HDF) instantly transforms the look of your images. By softening highlights and creating a delicate, cinematic look, this filter offers an expressive alternative to the traditional ultra-sharp look, which can be activated or deactivated with a simple press of the Fn button.

Ricoh's proprietary inkjet printing technology (multi-drop technology) made it possible to integrate the into the the shutter unit.
There are 2 effects as follows:
A: The white in the highlight area is more diffused to emphasize the light source
B: Reduce the contrast of the entire image (sharpness effect is about -2 to -3)

Emphasizing light creates a softer depiction, enabling emotional photographic expression reminiscent of film photography or cinema.
It is well-suited for constructing narratives, making it ideal for photography that tells a story through multiple images rather than relying on a single eye-catching, impactful shot.
Flashy filters have limited uses and quickly get bored; this filter effect is adjusted for long-term use across various everyday scenes.

New Electronic Shutter Function

GRIV HDF uses an electronic shutter for the faster shutter release.
This allows you to use the shutter speed up to 1/16000s while keeping the aperture wide open

It can shoot with appropriate exposure even in bright environments such as sandy beaches in the middle of summer, and HDF can also be used in the same environment to expand the opportunity for shooting

New function can be selected in the Shooting Settings

Electronic Shutter:
At F2.8: 1/3200 sec - 1/16000 sec
At 5.6-F16: 1/5000 sec - 1/16000 sec
