Ricoh GR IV: 30 years of street photography evolution in 262 grams

The Ricoh GR IV is the entry-level model in the fourth generation of the GR series, launched in September 2025. Compared to the previous generation, Ricoh completely redesigned the three main components—sensor, lens, and processor—while simultaneously reducing the body's dimensions. The result is a slimmer and more compact camera than the GR III, with improved image quality, a 0.6-second startup time, and optimized AF for low-light conditions. The only difference between the GR IV and the Ricoh GR IV HDF is the optical filter: the GR IV incorporates a 2 EV ND filter instead of the HDF filter, and the shutter release button is black.

What is the difference between the Ricoh GR IV and the Ricoh GR IV HDF?

The two cameras share the same sensor, processor, lens, IBIS, and all shooting and connectivity systems. The difference lies in the filter integrated into the shutter unit: the GR IV has a 2 EV ND filter (for controlling exposure in bright light while keeping the aperture wide open), while the GR IV HDF has a highlight diffusion filter for a cinematic visual effect. Both cameras have a dedicated Fn button for their respective filter. The shutter release button on the GR IV is black; the one on the GR IV HDF is silver-gray.

Is the Ricoh GR IV the camera you need?

It's for you if…

• Looking for the ultimate APS-C image quality in a pocket-sized format: 262g 109 × 61 × 33 mm with a fixed 28 mm equivalent f/2.8 lens and a 25.7 MP sensor.
• Outdoor photography in bright light requires the built-in ND filter: 2 EV automatic or manual reduction to maintain the AF/2.8 aperture even in bright daylight.
• Speed of reaction is paramount: 0.6s startup, low-light optimized AF, and fully pressed shooting function selectable directly from the mode dial.
• You value the storage autonomy: 53 GB internal for long sessions without a card.
• Want a sharp, natural image without added effects? The GR IV delivers the ultra-sharp result characteristic of the GR series without any contrast or diffusion modifications.

It's not for you if…

• Looking for a cinematic or analog look that can be activated on camera? That's the territory of the Ricoh GR IV HDF with its highlight diffusion filter.
• You need zoom or variable focal lengths: 28mm equivalent fixed lens, with digital cropping to 35mm and 50mm which reduces the effective resolution.
• Intensive video photography: ceiling in Full HD 1080p at 60p with a limit of 25 minutes per clip.

Frequently Asked Questions about the Ricoh GR IV

What is the difference between the Ricoh GR IV and the Ricoh GR IV HDF?

The difference lies in the integrated shutter unit filter. The GR IV features a 2 EV ND filter for controlling exposure in bright light. The GR IV HDF uses a High-Diffusion Filter (HDF) for a cinematic, analog look. Sensor, processor, optics, IBIS, and connectivity are identical in both models. The shutter release button on the GR IV is black; the one on the HDF is silver-gray.

Does the Ricoh GR IV have an electronic shutter?

No. The Ricoh GR IV does not include a high-speed electronic shutter—that's one of the features that differentiates it from the GR IV HDF, which does have one up to 1/16,000 s. The GR IV reaches 1/4000 s with a mechanical shutter (or 1/2500 saf/2.8) and has a built-in 2 EV ND filter for compensation in bright light.

What sensor does the Ricoh GR IV have?

A 23.3 × 15.5 mm APS-C CMOS sensor with 25.74 effective megapixels, GR ENGINE 7 processor, and 5-axis IBIS. It's the same sensor and processor combination as the GR IV HDF.

Does the Ricoh GR IV have image stabilization?

Yes. It incorporates 5-axis IBIS (Sensor Shift Image Stabilization "SR") with up to 6 steps of correction. When active, it also allows automatic horizon correction of up to 1 degree.

How much internal memory does the Ricoh GR IV have?

53 GB of internal memory, for approximately 3,498 JPEG-L images (26 MP, 3:2) or 995 14-bit RAW DNG images without a microSD card. It also accepts microSD/microSDHC/microSDXC cards with UHS-I standard.
