Canon G1 X Mark III versus Sony RX100 IV
The Canon PowerShot G1 X Mark III and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were officially introduced, respectively, in October 2017 and June 2015. Both the G1X Mark III and the RX100 IV are fixed lens compact cameras that are based on an APS-C (G1X Mark III) and an one-inch (RX100 IV) sensor. The Canon has a resolution of 24 megapixel, whereas the Sony provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Canon G1 X Mark III vs Sony RX100 IV
An illustration of the physical size and weight of the Canon G1 X Mark III and the Sony RX100 IV is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size 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 side – the G1X Mark III – represents the basis for the calculations 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 Sony RX100 IV is considerably smaller (34 percent) than the Canon G1 X Mark III. Moreover, the RX100 IV is markedly lighter (25 percent) than the G1X Mark III. It is worth mentioning in this context that the G1X Mark III is splash and dust resistant, while the RX100 IV does not feature any corresponding weather-sealing.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 IV was launched at a somewhat lower price (by 23 percent) than the G1X Mark 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.
Sensor comparison: Canon G1 X Mark III vs Sony RX100 IV
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.
Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. 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 RX100 IV (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the RX100 IV) due to its larger sensor. Moreover, the G1X Mark III is a somewhat more recent model (by 2 years and 4 months) than the RX100 IV, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Both the G1X Mark III and the RX100 IV have zoom lenses build in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the RX100 IV offers a 24-70mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The RX100 IV 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 RX100 IV has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 IV was succeeded by the Sony RX100 IV.

The above review scores should be interpreted 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
