Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX10 III and the Sony Cyber-shot DSC-RX10? 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 side-by-side display below illustrates the physical size and weight of the Sony RX10 III and the Sony RX10. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 Sony RX10 is notably smaller (9 percent) than the Sony RX10 III. Moreover, the RX10 is markedly lighter (23 percent) than the RX10 III. 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.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 RX10 was launched at a somewhat lower price (by 13 percent) than the RX10 III, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the RX10 III and the RX10 have the same pixel density, as well as the same pixel size. It should, however, be noted that the RX10 III is much more recent (by 2 years and 5 months) than the RX10, and its sensor will have benefitted from technological advances during this time.

The Sony Cyber-shot DSC-RX10 III has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 64-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX10 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX10 III provides a higher video resolution than the RX10. It can shoot video footage at 4K/30p, while the RX10 is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the RX10 III offers a substantially higher resolution than the one in the RX10 (2359k vs 1440k dots).

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 RX10 III 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).

Both the RX10 III and the RX10 have zoom lenses built in. The RX10 III has a 24-600mm f/2.4-4.0 optic and the RX10 offers a 24-200mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the RX10 III and RX10 provide the same view at the wide-angle end, but the RX10 has less tele-photo reach at the long end. The RX10 III offers the faster maximum aperture.

Concerning the storage of imaging data, both the RX10 III and the RX10 write their files to SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of 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 Sony Cyber-shot DSC-RX10 III and Sony Cyber-shot DSC-RX10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Further information on the features and operation of the RX10 III and RX10 can be found, respectively, in the Sony RX10 III Manual (free pdf) or the online Sony RX10 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Sony RX10 III and the Sony RX10? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Sony Cyber-shot DSC-RX10 III:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1440k dots).
• Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.4 vs f/2.8).
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• More modern: Reflects 2 years and 5 months of technical progress since the RX10 launch.

Reasons to prefer the Sony Cyber-shot DSC-RX10:

• Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
• Less heavy: Has a lower weight (by 238g or 23 percent) and is thus easier to take along.
• More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in October 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the RX10 III emerges as the winner of the contest (7 : 4 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 Sony RX10 III and the Sony RX10 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the RX10 III and the RX10 in practical situations. 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
