Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X100VI and the Sony Cyber-shot DSC-RX1R III? 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

The physical size and weight of the Fujifilm X100VI and the Sony RX1R III are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The X100VI can be obtained in two different colors (black, silver), while the RX1R III is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX1R III is notably smaller (20 percent) than the Fujifilm X100VI. Moreover, the RX1R III is slightly lighter (4 percent) than the X100VI. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

Concerning battery life, the X100VI gets 450 shots out of its Fujifilm NP-W126S battery, while the RX1R III can take 300 images on a single charge of its Sony NP-FW50 power pack. 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.

Any camera decision will obviously take relative prices into account. 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 X100VI was launched at a markedly lower price (by 69 percent) than the RX1R III, 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 sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Fujifilm X100VI features an APS-C sensor and the Sony RX1R III a full frame sensor. The sensor area in the RX1R III is 131 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 60.2MP, the RX1R III offers a higher resolution than the X100VI (39.8MP), but the RX1R III nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 3.04μm for the X100VI) due to its larger sensor. Moreover, the RX1R III is a somewhat more recent model (by 1 year and 4 months) than the X100VI, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Sony RX1R III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R III for good quality output (200 dots per inch) amounts to 47.5 x 31.7 inches or 120.7 x 80.5 cm, for very good quality (250 dpi) 38 x 25.3 inches or 96.6 x 64.4 cm, and for excellent quality (300 dpi) 31.7 x 21.1 inches or 80.5 x 53.6 cm. The corresponding values for the Fujifilm X100VI are 38.6 x 25.8 inches or 98.1 x 65.4 cm for good quality, 30.9 x 20.6 inches or 78.5 x 52.3 cm for very good quality, and 25.8 x 17.2 inches or 65.4 x 43.6 cm for excellent quality prints.

The Fujifilm X100VI has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 64-51200. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1R III are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. The X100VI uses Fujifilm's X-Trans layout of photosites, while the RX1R III employs the more common Bayer array.

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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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, both cameras under consideration feature an 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 X100VI and the Sony RX1R III 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 X100VI and the RX1R III have built-in prime lenses. Both optics share the same full frame equivalent focal length (23mm) and have identical aperture specifications (f/2.0). Both cameras offer the same maximum aperture.

Concerning the storage of imaging data, both the X100VI and the RX1R III write their files to SDXC cards. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 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 Fujifilm X100VI and Sony Cyber-shot DSC-RX1R III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the X100VI and the RX1R III are recent models that are part of the current product line-up. The X100VI replaced the earlier Fujifilm X100V, while the RX1R III followed on from the Sony RX1R II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Fujifilm and Sony websites.

Review summary

So what conclusions can be drawn? Is the Fujifilm X100VI better than the Sony RX1R III or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Fujifilm X100VI:

• Better video: Provides higher definition movie capture (6.2K/30p vs 4K/30p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (3690k vs 2360k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (11 vs 5 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (450 versus 300) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in February 2024).

Arguments in favor of the Sony Cyber-shot DSC-RX1R III:

• More detail: Has more megapixels (60.2 vs 39.8MP), which boosts linear resolution by 23%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.7x vs 0.44x).
• More detailed LCD: Has a higher resolution rear screen (2360k vs 1620k dots).
• More compact: Is smaller (113x68mm vs 128x75mm) and will fit more readily into a bag.
• More modern: Was introduced somewhat (1 year and 4 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the RX1R III emerges as the winner of the match-up (10 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 X100VI and the Sony RX1R III 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X100VI or the RX1R III perform in practice. 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 why expert reviews 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
