The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The GR IIIx was launched at a markedly lower price (by 80 percent) than the GFX 100RF, which puts it into a different market segment. 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.
Sensor comparison
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Fujifilm GFX 100RF features a medium format sensor and the Ricoh GR IIIx an APS-C sensor. The sensor area in the GR IIIx is 75 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.79 and 1.5. The sensor in the GFX 100RF has a native 4:3 aspect ratio, while the one in the GR IIIx offers a 3:2 aspect.

With 101.8MP, the GFX 100RF offers a higher resolution than the GR IIIx (24MP), but the GFX 100RF has smaller individual pixels (pixel pitch of 3.76μm versus 3.91μm for the GR IIIx). However, the GFX 100RF is a much more recent model (by 3 years and 6 months) than the GR IIIx, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Fujifilm GFX 100RF implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GFX 100RF for good quality output (200 dots per inch) amounts to 58.2 x 43.7 inches or 147.9 x 110.9 cm, for very good quality (250 dpi) 46.6 x 34.9 inches or 118.3 x 88.8 cm, and for excellent quality (300 dpi) 38.8 x 29.1 inches or 98.6 x 74 cm. The corresponding values for the Ricoh GR IIIx are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.
The Fujifilm GFX 100RF has a native sensitivity range from ISO 80 to ISO 12800, which can be extended to ISO 40-102400. The corresponding ISO settings for the Ricoh GR IIIx are ISO 100 to ISO 102400 (no boost).
In terms of underlying technology, the GFX 100RF is build around a 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GFX 100RF provides a higher video resolution than the GR IIIx. It can shoot video footage at 4K/30p, while the Ricoh is limited to 1080/60p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GFX 100RF has an electronic viewfinder (5760k 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 table below summarizes some of the other core capabilities of the Fujifilm GFX 100RF and Ricoh GR IIIx in connection with corresponding information for a sample of similar cameras.

| Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. | |||||||||||
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 GFX 100RF 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 Fujifilm GFX 100RF 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.
Both the GFX 100RF and the GR IIIx have built-in prime lenses. The GFX 100RF has a 28mm f/4.0 optic and the GR IIIx offers a 40mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Fujifilm provides a wider angle of view than the Ricoh. The GR IIIx offers the faster maximum aperture.
Concerning the storage of imaging data, both the GFX 100RF and the GR IIIx write their files to SDXC cards. The GFX 100RF 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 GFX 100RF supports UHS-II cards (on both slots), while the GR IIIx can use UHS-I cards.
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.

If the number of relative strengths (bullet points above) is taken as a guide, the GFX 100RF is the clear winner of the match-up (20 : 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 Fujifilm GFX 100RF and the Ricoh GR IIIx place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GFX 100RF or the GR IIIx. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
Expert reviews
This is why hands-on reviews by experts are important. 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 review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
