Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS R1 and the Ricoh GR IIIx? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison
An illustration of the physical size and weight of the Canon R1 and the Ricoh GR IIIx is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Ricoh GR IIIx is considerably smaller (71 percent) than the Canon R1. It is worth mentioning in this context that the R1 is splash and dust resistant, while the GR IIIx does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the GR IIIx has a lens built in, whereas the R1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the R1 gets 1330 shots out of its Canon LP-E19 battery, while the GR IIIx can take 200 images on a single charge of its Ricoh DB-110 power pack. As can be seen in the images above, the R1 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The GR IIIx was launched at a lower price than the R1, despite having a lens built in. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon R1 features a full frame sensor and the Ricoh GR IIIx an APS-C sensor. The sensor area in the GR IIIx is 58 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the R1 has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the R1 has a lower pixel density and larger individual pixels (with a pixel pitch of 6.00μm versus 3.91μm for the GR IIIx), which gives it a potential advantage in terms of light gathering capacity. In addition, the R1 is much more recent (by 2 years and 10 months) than the GR IIIx, and its sensor will have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that the GR IIIx has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon EOS R1 has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-409600. The corresponding ISO settings for the Ricoh GR IIIx are ISO 100 to ISO 102400 (no boost).
In terms of underlying technology, the R1 is build around a Stacked BSI-CMOS sensor, while the GR IIIx uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports").

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the R1 provides a higher video resolution than the GR IIIx. It can shoot video footage at 6K/60p, while the Ricoh is limited to 1080/60p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the R1 has an electronic viewfinder (9440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GR IIIx relies on live view and the rear LCD for framing. That said, the GR IIIx can be equipped with an optional viewfinder – the GV-3. The adjacent table lists some of the other core features of the Canon R1 and Ricoh GR IIIx along with similar information for a selection of comparators.

One feature that is present on the R1, but is missing on the GR IIIx is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The R1 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the GR IIIx does not have a selfie-screen.The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the R1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Canon R1 and the Ricoh GR IIIx both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The R1 writes its imaging data to CFexpress (type B) or SDXC cards, while the GR IIIx uses SDXC cards. The R1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GR IIIx only has one slot. The R1 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the GR IIIx can use UHS-I cards (up to 104 MB/s).
Connectivity comparison
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon EOS R1 and Ricoh GR IIIx and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the R1 has a microphone port, which is missing on the GR IIIx. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Canon R1 (unlike the GR IIIx) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the R1 and the GR IIIx are recent models that are part of the current product line-up. The GR IIIx replaced the earlier Ricoh GR II, while the R1 does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Ricoh websites.
Review summary
So what is the bottom line? Which of the two cameras – the Canon R1 or the Ricoh GR IIIx – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS R1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features a larger and more technologically advanced imaging sensor.

- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Reflects 2 years and 10 months of technical progress since the GR IIIx launch.

Arguments in favor of the Ricoh GR IIIx:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Ready to shoot: Has an integrated lens, whereas the R1 necessitates an extra lens.
- More compact: Is smaller (109x62mm vs 158x150mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the R1).
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been around for much longer (launched in September 2021).
If the number of relative strengths (bullet points above) is taken as a guide, the R1 is the clear winner of the match-up (26 : 6 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon R1 and the Ricoh GR IIIx place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the R1 or the GR IIIx. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
Expert reviews
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
