Ricoh GR IIIx HDF review: a street shooter with a dreamy diffusion filter

Ricoh GR IIIx HDF: two-minute review

With its large APS-C sensor and fixed 40mm f/2.8 lens, we already rated the Ricoh GR IIIx as one of the best premium compact cameras for travel and street photography. This version features a niche tweak that gives it a specific appeal: where the original had a built-in ND filter, the GR IIIx HDF instead has a highlight diffusion filter.

There’s no software trickery at work here. This is a physical filter that’s built into the shutter unit and is enabled with a push of the Fn button, and it reduces contrast and blurs bright whites, producing soft, dreamy stills with an ethereal glow that harks back to the days of analog.

Based on our time with both the GR IIIx and the HDF version, the latter is the more creative tool. Whether you’re capturing reflections shimmering off water or sunlight through leaves, it allows you to experiment with unique, film-like lighting effects.

The GR IIIx HDF also benefits from a couple of new firmware features: there’s support for up to three custom white balances, while zone-select AF gives you more flexibility to target automatic focusing within the center area. These are minor tweaks which will also be introduced to the GR III / IIIx down the line.

Otherwise, the GR IIIx HDF is identical to the existing version. That includes everything from the pocket-friendly dimensions and direct access controls to the APS-C sensor and 40mm lens combination we praised in our original review. It also retains the same drawbacks, though, including average battery life and a fixed screen.

The GR IIIx HDF isn’t the major update that many Ricoh fans were hoping for, and it’s certainly not worth buying if you already own the GR IIIx. But if you’re choosing between the two versions, we think the highlight diffusion filter makes it the more artful and unique option, especially if you’re a fan of the vintage aesthetic. It costs marginally more, but it’s the one we’d pick.

Ricoh GR IIIx HDF: price and availability

• Launched on 28 March 2024, alongside the GR III HDF
• Priced at $1,146 / £1,099 / AU$1,899

The Ricoh GR IIIx HDF was announced in March 2024 with a launch price of $1,146 / £1,099 / AU$1,899. That makes it $147 / £100 / AU$120 more expensive than the standard Ricoh GR IIIx, which already commanded a pretty premium ask. At that price, the GR IIIx HDF is close to mid-range mirrorless money, with cameras like the Sony A7 III available for a similar amount.

While that might seem hard to justify for a compact with a fixed lens, the point here is that Ricoh is making a niche version of an already niche camera. You’ll buy the GR IIIx HDF not because you want the best possible performance for the money, but because you want a sharp-shooting compact with a relatively large sensor, with the added value of a unique built-in filter.

If you’re in the market for one of the best travel cameras, the GR IIIx offers better value objectively. Whether the highlight diffusion filter is worth the extra expenditure will come down to how you plan to use the camera and whether you’ll appreciate the creative aesthetic it’s capable of. But for our money, it’s the more compelling proposition, even with the increase in cost.

Ricoh GR IIIx HDF: design

• Physically identical to the GR IIIx
• Truly pocketable dimensions
• 3-inch, 1.03 million-dot touchscreen

Other than its silver shutter button, the GR IIIx HDF is identical to the GR IIIx. That means it’s a genuinely pocket-friendly compact, measuring a tidy 109.4 x 61.9 x 35.2mm and weighing an impressively light 262g, including the battery and an SD card. It’s pretty much as small as a camera with an APS-C sensor inside can be, making it a portable yet powerful shooting tool.

Not only do those dimensions mean the GR IIIx HDF is a convenient camera to travel with, but it’s also one you can comfortably use with one hand, making it ideal for discreet street photography. Ergonomically, there’s enough of a front grip to get your fingers around, with a moulded thumb rest on the rear.

Direct-access controls are plentiful, including a mode dial and scroll lever for adjusting exposure, and are neatly set out within easy reach of your thumb. Most prominent among them is the function button, which by default is used to activate the highlight diffusion filter. The control layout doesn’t clutter the body, but the camera’s proportions mean some of the rear inputs do require a bit of nimble finger-work to avoid accidentally hitting other buttons.

Like the GR IIIx, the HDF version has a fixed 3-inch LCD touchscreen. It’s sharp enough at 1.03 million dots, although it’s not the brightest, which can make framing in direct sunlight slightly tricky. That’s not helped by the absence of an electronic viewfinder and, while there is a hot-shoe mount on top of the body, the only optional viewfinders available from Ricoh are analog ones.

All that being said, the GR IIIx HDF is just as fun to use as the standard GR IIIx. The touchscreen is responsive, and touch-focus support makes it as easy to shoot with as any smartphone. Its point-and-shoot design also strikes a good balance between accessibility for beginners and creative control for more experienced users.

Ricoh GR IIIx HDF: features and performance

• Highlight diffusion filter
• Fixed-focal-length f/2.8 lens
• New zone-select AF functionality

The headline feature of the GR IIIx is its highlight diffusion filter, which replaces the neutral density filter found in the GR IIIx. The HDF is a physical filter that’s part of the shutter unit, and it has the effect of reducing contrast and softening bright whites when enabled. The net effect of this is dreamy stills with a blurry glow that mimics the look of film photography.

Based on our tests, it’s more than a gimmick. The effect’s strength depends on what and where you’re shooting, but it can be surprisingly potent. In backlit or overcast scenes we found that it could lead to unwanted halo effects; but in the right conditions, such as warm sunlight filtering through trees or lights reflecting off water at night, the filter makes the GR IIIx HDF capable of producing some genuinely unique, creative images.

On paper, it’s a niche feature. But at a time when analog is all the rage again we can see it appealing to a lot of people. Not only does the GR IIIx HDF produce images with a film-like aesthetic, it does so by way of a genuine physical filter, which lends the results a feeling of authenticity which can’t be achieved with post-processing. It also makes the GR IIIx HDF feel like a fun tool to experiment with creatively, with none of the associated costs of film.

Otherwise, the Ricoh GR IIIx HDF shares most of the rest of its features and spec sheet with the standard version. That’s true of the effective sensor-shift shake reduction system, useful Snap Focus tool and decent macro mode. Unfortunately, it’s also true of the modest 200-shot battery life, lazy burst speeds, and maximum Full HD video resolution.

Also inherited is the 40mm f/2.8 lens, which offers a focal length that’s more versatile for portrait work than the 28mm lens of the GR III. The depth of field is lovely and shallow, although you do need to be careful when using Snap Focus as it’s easy to miss your focus point. Rather than repeat the same observations here, we recommend reading our GR IIIx review for a full insight into how these features stack up in real-world use.

Operation of the HDF version is just as quick as with the GR IIIx, with rapid start-up and shutter response times. Less impressive is the autofocus performance, which suffers from the same laggy tracking as before. One thing that is new for the GR IIIx is zone-select AF. This essentially allows you to zone the AF in on a specific region within the auto-area AF coverage. We could see this being useful for street portraits, but it’s a relatively minor addition, and one that’s also due to be added to existing models in a later firmware update.

More useful is the introduction of three programmable white balance settings, which means you can easily shift between different custom presets without having to dive into the manual settings. We think many users of the GR IIIx HDF are likely to use auto white balance, but it’s nevertheless a welcome addition.

How I tested the Ricoh GR IIIx HDF

• I used the camera for two weeks
• I shot more than 150 stills
• I took pictures in a range of conditions

Testing the Ricoh GR IIIx HDF involved taking it out into the world and using it as I would use any camera day to day. I took more than 150 photos over the course of a fortnight, in a whole range of shooting scenarios and lighting conditions, from day to night, and from portraits to street details.

As the highlight diffusion filter is the key point of difference between this camera and the standard GR IIIx, I focused in particular on capturing images with the HDF enabled. I also shot a range of reference images across different shooting modes, to assess the actual effect of the filter.
