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 G7X Mark II was launched at a somewhat lower price (by 13 percent) than the RX100 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 G7 X Mark II vs Sony RX100 III

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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.

Canon G7 X Mark II and Sony RX100 III sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixel. This similarity in sensor specs implies that both the G7X Mark II and the RX100 III have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7X Mark II is a somewhat more recent model (by 1 year and 9 months) than the RX100 III, and its sensor might have benefitted from technological advances during this time.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon G7 X Mark II vs Sony RX100 III

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX100 III has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X Mark II relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G7 X Mark II and Sony RX100 III in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the G7X Mark II and the RX100 III have zoom lenses build in. The G7X Mark II has a 24-100mm f/1.8-2.8 optic and the RX100 III 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. Both cameras offer the same maximum aperture.

The G7X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 III was succeeded by the Sony RX100 IV.

Review summary: Canon G7 X Mark II vs Sony RX100 III

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 before making a camera decision.

G7X Mark II 04:05 RX100 III

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G7X Mark II and the RX100 III in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
