Canon G1 X Mark III versus Sony RX10 IV

The Canon PowerShot G1 X Mark III and the Sony Cyber-shot DSC-RX10 IV are two enthusiast cameras that were revealed to the public, respectively, in October 2017 and September 2017. Both the G1X Mark III and the RX10 IV are fixed lens compact cameras that are based on an APS-C (G1X Mark III) and an one-inch sensor. The Canon has a resolution of 24 megapixel, whereas the Sony provides 20 MP.

Body comparison

The physical size and weight of the Canon G1 X Mark III and the Sony RX10 IV are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter.

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 24 percent) than the RX10 IV, 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

The size of the imaging sensor is a crucial determinant 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. 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 more expensive and 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 RX10 IV an one-inch sensor. The sensor area in the RX10 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.

Sensor size

With 24MP, the G1X Mark III offers a higher resolution than the RX10 IV (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the RX10 IV) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

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 IV provides a better video resolution than the G1X Mark III. It can shoot movie footage at 4K/30p, while the Canon 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 G1X Mark III offers a slightly higher resolution than the one in the RX10 IV (2360k vs 2359k dots). The table below summarizes some of the other core capabilities of the Canon G1 X Mark III and Sony RX10 IV in connection with corresponding information for a sample of similar cameras.

Both the G1X Mark III and the RX10 IV have zoom lenses build in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the RX10 IV offers a 24-600mm f/2.4-4.0 (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 more tele-photo reach at the long end. The RX10 IV offers the faster maximum aperture.

Both the G1X Mark III and the RX10 IV are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The RX10 IV replaced the earlier Sony RX10 III, while the G1X Mark III followed on from the Canon G1 X Mark II.

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 G1X Mark III and the RX10 IV 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
