What is the HDF filter and why is it the differentiating element of the Ricoh GR IV HDF?
The HDF (Highlight Diffusion Filter) is a physical filter integrated into the shutter unit using Ricoh's proprietary inkjet printing technology. It's not a post-processing effect or a digital filter; it acts on the light before it reaches the sensor. Its effect has two simultaneous components: it diffuses the highlighted areas, emphasizing the light source, and reduces the overall image contrast by approximately 2 to 3 stops of sharpness. The result is a cinematic, analog look that can be activated or deactivated with a single press of the Fn button, without interrupting the shooting flow. Unlike conventional effect filters, the HDF is calibrated for extended use in everyday scenes—it's not a one-off effect but an alternative workflow for those who construct visual narratives with multiple images rather than relying on a single, impactful shot.
What is the difference between the Ricoh GR IV HDF and the Ricoh GR IV?
The two cameras share the same sensor, processor, lens, and shooting specifications. The only difference is the HDF filter and two related details: the GR IV HDF's shutter release button is silver-gray instead of black—a visual detail Ricoh uses to identify the HDF model—and the default Fn button setting toggles HDF on and off instead of another function. The standard GR IV does not have an HDF filter, nor is it available as an accessory.
Is the Ricoh GR IV HDF the camera you need?
It's for you if…
- Photographs taken on the street, while traveling, or in everyday situations where the size and weight of the camera determine whether you take it or not — 262g and 109 × 61 × 33 mm fit in any pocket.
- Looking for your own visual signature and not satisfied with the standard ultra-sharp look? The HDF filter delivers a cinematic result that can be activated at any time without post-processing.
- You need APS-C quality with a fixed lens: the GR LENS 18.3mm f/2.8 (28mm equivalent) with 7 elements in 5 groups delivers center-to-edge sharpness that no smaller sensor compact camera can match.
- Shoot in low light: ISO up to 204800 with advanced noise management and 5-axis IBIS compensate for the limitations of difficult lighting environments.
- You value the storage autonomy: the 53 GB of internal memory allows you to work without a card during long sessions.
It's not for you if…
- You need zoom or variable focal lengths: the GR IV HDF has a fixed 28mm equivalent lens. Digital cropping to 35mm and 50mm reduces the effective resolution.
- It takes intensive photos and videos: the ceiling is Full HD 1080p at 60p with a limit of 25 minutes per clip — it does not have 4K.
- You need a built-in flash: the GR IV HDF does not include one — it has a hot shoe for a dedicated external flash.

Frequently Asked Questions about the Ricoh GR IV HDF
What is the difference between the Ricoh GR IV HDF and the Ricoh GR IV?
The only difference is the HDF (Highlight Diffusion Filter), which is physically integrated into the shutter unit of the GR IV HDF. The sensor, processor, optics, IBIS, and connectivity specifications are identical. The standard GR IV does not have an HDF and cannot be added. As a visual distinguishing feature, the shutter release button on the GR IV HDF is silver-gray, while the one on the GR IV is black.
What is the HDF filter of the Ricoh GR IV HDF?
The HDF (Highlight Diffusion Filter) is a physical filter integrated into the shutter unit that diffuses highlights and reduces overall image contrast by 2 to 3 stops, creating a cinematic, analog look. It is activated and deactivated with the Fn button without interrupting the shooting process. It is not a post-processing effect—it acts on the light before it reaches the sensor.
What is the difference between the Ricoh GR IV HDF and the Ricoh GR IIIx HDF?
The GR IV HDF incorporates the new 25.7 MP back-illuminated APS-C sensor, the GR ENGINE 7 processor, 5-axis IBIS, Wi-Fi 6, Bluetooth 5.3, electronic shutter up to 1/16,000 s and 53 GB of internal memory — substantial improvements over the GR IIIx HDF in all technical aspects while maintaining the same physical HDF filter concept.
Does the Ricoh GR IV HDF have image stabilization?
Yes. It incorporates 5-axis IBIS (Integrated Brain-Steering Image Stabilization), called "SR" by Ricoh. When active, it also allows automatic horizon correction of up to 1 degree.
How much internal memory does the Ricoh GR IV HDF have?
53 GB of internal memory, enough for approximately 3,498 JPEG-L images (3:2, 26 MP) or 995 14-bit DNG RAW images without needing a microSD card. It also accepts microSD/microSDHC/microSDXC cards with UHS-I standard.
