What's New

Updated sensor

The GR IV uses a 25.74MP backside-illuminated sensor, compared to the 24MP frontside-illuminated one found in the GR III. The bump in resolution will be essentially irrelevant, and we'll have to test it more to see if it provides any noticeable improvements in areas like noise performance, dynamic range or readout speed. It seems likely that it's the same sensor Sony uses for its a6700 and Pentax in the K-3 III, which would mean Ricoh is continuing its tradition of using tried-and-true imaging tech in the GR series.

In large sensors, the benefits of BSI tend to have more to do with getting even illumination at the corners of the sensor, rather than having much impact on overall noise.

Redesigned lens

Also getting an update is the 18.3mm (28mm equiv) F2.8 lens. Ricoh has refreshed the formula, adding another aspherical element, which it says should provide better detail and sharpness in the corners. More importantly, the lens barrel is thinner, which means it can extend faster, improving the camera's startup time by 0.2 seconds. This may not sound like much, but it's a 25% improvement.

The company also says it focused on making the lens suck in less dust when it retracts and extends. While it's still not making any claims about weather or dust resistance, it clearly saw users' complaints about their previous GR cameras getting dust on the sensor, as it's also added a new anti-fouling and anti-static coating to the UV/IR cut filter. That should make it easier for the sensor's cleaning routine to shake off any dust that makes it into the body.

New old control layout

Left: GR IV. Right: GR III

The GR IV's control scheme reverses several changes made with the GR III, and so more closely resembles the layout of the original GR and GR II. Most notably, it replaces the rear-plate control dial with a multi-directional controller, and regains the "+ / –" rocker switch the III dropped.

It isn't just a complete remake of the GR II, though. The rear jog lever that's been on all of the GR cameras up to this point has been replaced with a clickable command dial. The company has also added a position for the Snap Distance Priority mode, introduced via a firmware update to the GR III, onto the camera's mode dial. It makes the camera's zone focusing system a little more approachable, letting you control your focus distance with one dial, and the depth of field with the other, with the camera setting your other exposure settings accordingly.

The Program auto mode has also received a substantial rework, adopting Pentax's Hyper Program mode in all but name. You can now use the dials to override it to either prioritize aperture or shutter speed, using the command dials, and can reset back to auto with a press of the mode dial's lock button.

Upgraded internals and battery

The GR IV has a new image processor, which the company says can provide more sophisticated noise reduction and more accurate color reproduction in the out-of-camera JPEGs. It's also paired with new autofocus algorithms, which should improve its focusing speed and accuracy, especially in more difficult scenarios, according to Ricoh.

The sensor stabilization system has also been upgraded, moving from a three-axis design to a five-axis one, providing a bump from a 4EV rating of stabilization to 6EV.

Additionally, Ricoh has massively increased the amount of internal storage; while the GR III had around 2GB built-in, the GR IV has 53GB, which, for many users, may be enough to obviate a separate memory card. Which may be a relief, given that Ricoh has chosen to go with a Micro SD card slot, rather than a full-size one, this time around, to make way for other changes.

A flashy accessory

The GF-2 is sold separately, but provides a reasonably-priced, compact option for those who miss the original GR's built-in flash.

Alongside the GR IV, Ricoh is launching the GF-2, a sold-separately external flash designed to be compact and to fit the camera's design. It has a guide number of 3 at ISO 100, and has its own battery and charges via USB-C, so using it won't wear down the camera's battery. And while it's not a TTL flash, it is aware of the camera's exposure settings and focus distance, allowing for an automatic mode, though it can also be used manually.

Ricoh says that its customers are split on whether they care about the GR having an internal flash, but that they universally care about it being compact and pocketable. According to the company, the external flash lets the camera be as small as possible while making it so those who don't care about having it don't have to pay for its inclusion.

The flash doesn't power on with the camera, as you may not wish to use it every time, but it is clever enough to power down when you switch the camera off.

How does it compare?

Specs-wise, the GR IV is a mild update to the GR III, but there are enough differences to its core specs that we felt it was worth a direct comparison. We've also included Fujifilm's fixed-lens X100 VI; while its 35mm equiv. focal length will likely appeal to a different set of shooters, it's arguably the most famous of the photographer's fixed-lens cameras out there today. And while the RX100 VII's zoom lens and smaller sensor make for a very different shooting experience than the fixed lens APS-C cameras on this list, its size may make it attractive to the same photographers considering a GR.

While it's certainly not large, the X100 VI is substantially bulkier and heavier than the GR III/IV. However, there are reasons why: you get better battery life, a faster lens and a viewfinder experience that can be very engaging to shoot with. It's not the best option if you're looking for the most pocketable option, but it's still a portable and engaging fixed-lens camera, with features like a built-in flash and weather resistance that some fans of the Ricoh GR series have been asking for.

The RX100 VII is the oldest camera on this list, and that manifests in several ways; while its older autofocus system was once top-of-the-pack (and is still mostly competitive today), Sony's latest versions are even better. The menu system hasn't aged as gracefully, as it arguably wasn't very good to begin with, and the Micro USB port means that most people will have to carry a separate charger for it. However, its zoom lens and stacked sensor make it a more versatile pick for those looking for a camera that can also handle sports and action.

Body and Handling

The GR IV retains the same utilitarian styling that the GR series has always been known for, though it is now slightly slimmer and shorter. The difference is subtle on the spec sheet, but is noticeable in the hand and the pocket.

The heart of the camera is its controls, which can be operated entirely with one hand. The two top-plate command dials are placed near where your thumb and forefinger naturally rest, giving you quick control over your exposure settings.

Pressing the rear dial brings up the 'ADJ' quick settings menu, which is entirely customizable. You can choose up to five categories of settings accessible from the menu, with 17 options such as color mode, drive mode, ISO settings, focus mode and so on. One dial switches between the categories, while the other lets you make your selection from them.

You can pare the Adjust menu down to contain just your essentials.

By default, the menu will pop back up until you confirm your selection, though you can set the camera to do so with a half-press of the shutter. This customizability carries over to the rest of the camera, too, with over thirty settings for the function button and granular control over what a half-press of the shutter button does.

The menu system is also entirely navigable by touch if you prefer a more direct form of interaction. While it can be set to take a photo when you tap the screen, the menu doesn't live on the live view display, making it all too easy to accidentally toggle between touch-to-focus and touch-shutter modes.

In short, the GR IV gives you plenty of room to set it up in a way that suits your shooting style. It's extremely quick to operate once you have it dialed in, letting you change your most-accessed settings on the fly while staying in the moment, and making it easy to focus on the essentials of photography, rather than your camera.

Display

The 3.0" rear LCD's resolution is unchanged from the previous model, and while it's not particularly high-resolution, it's sufficient for composing and checking focus after the fact (as long as you punch in to 1:1). It now has an auto-brightness setting, which monitors the ambient light through the lens and makes adjustments accordingly. Even when shooting on very sunny days, we found it relatively visible given its fixed placement on the back of the camera.

While the camera doesn't have a viewfinder, it is still compatible with the add-on optical viewfinders released for the GR III. The company says it plans on releasing new models more suited to the new camera's reduced depth, but that the older models should still fit reasonably well.
