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 announced, 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 (G1X Mark III) sensor. The Sony has a resolution of 20 megapixel, whereas the Canon provides 24 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: Sony RX10 III vs Canon G1 X Mark III

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 views from the front, the top, and the rear side are shown.

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 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.

 

Sensor comparison: Sony RX10 III vs Canon G1 X Mark III

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 are more costly to manufacture and tend to lead to bigger and heavier cameras 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.

Sony RX10 III and Canon G1 X Mark III sensor measures

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.

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 G1X Mark III. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Sony RX10 III vs Canon G1 X Mark III

Apart from 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).

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.

RX10 III 08:08 G1X Mark III

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX10 III and the G1X Mark III 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. This is why hands-on reviews by experts are important.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
