Sony RX10 III versus Canon G1 X Mark III
The Sony Cyber-shot DSC-RX10 III and the Canon PowerShot G1 X Mark III are two enthusiast cameras that were officially introduced, respectively, in March 2016 and October 2017. Both the RX10 III and the G1X Mark III are fixed lens compact cameras that are based on an one-inch (RX10 III) and an APS-C sensor. The Sony has a resolution of 20 megapixel, whereas the Canon provides 24 MP.
The side-by-side display below illustrates the physical size and weight of the Sony RX10 III and the Canon G1 X Mark III. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the RX10 III – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G1 X Mark III is notably smaller (28 percent) than the Sony RX10 III. Moreover, the G1X Mark III is substantially lighter (62 percent) than the RX10 III. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G1X Mark III 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. 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.
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Sony RX10 III features an one-inch sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 24MP, the G1X Mark III offers a higher resolution than the RX10 III (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the RX10 III) due to its larger sensor. Moreover, the G1X Mark III is a somewhat more recent model (by 1 year and 6 months) than the RX10 III, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
For most 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 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 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 RX10 III provides a higher video resolution than the G1X Mark III. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the G1X Mark III offers a slightly higher resolution than the one in the RX10 III (2360k vs 2359k dots). The following table reports on some other key feature differences and similarities of the Sony RX10 III, the Canon G1 X Mark III, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the RX10 III and the G1X Mark III have zoom lenses build in. The RX10 III has a 24-600mm f/2.4-4.0 optic and the G1X Mark III offers a 24-72mm f/2.8-5.6 (focal lengths in full frame equivalent terms). Hence, the Sony and Canon provide the same view at the wide-angle end, but the Canon has less tele-photo reach at the long end. The RX10 III offers the faster maximum aperture.
The G1X Mark III is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX10 III has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX10 III was succeeded by the Sony RX10 IV.

If the number of relative strengths (bullet points above) is taken as a guide, the G1X Mark III emerges as the winner of the match-up (9 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.
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 handling experience and imaging performance when actually working with the RX10 III or the G1X Mark III. 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. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
