Sony RX100 versus Canon G9 X Mark II
The Sony Cyber-shot DSC-RX100 and the Canon PowerShot G9 X Mark II are two digital cameras that were officially introduced, respectively, in June 2012 and January 2017. Both the RX100 and the G9X Mark II are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.
An illustration of the physical size and weight of the Sony RX100 and the Canon G9 X Mark II is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 RX100 – 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 Canon G9 X Mark II is somewhat smaller (4 percent) than the Sony RX100. Moreover, the G9X Mark II is markedly lighter (14 percent) than the RX100. In this context, it is worth noting that neither the RX100 nor the G9X Mark II are weather-sealed.
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 G9X Mark II was launched at a somewhat lower price (by 18 percent) than the RX100, 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 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tent 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.
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 RX100 and the G9X Mark II have the same pixel density, as well as the same pixel size. It should, however, be noted that the G9X Mark II is much more recent (by 4 years and 7 months) than the RX100, and its sensor will have benefitted from technological advances during this time.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a variety of features. The RX100 and the G9X Mark II are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The following table reports on some other key feature differences and similarities of the Sony RX100, the Canon G9 X Mark II, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the RX100 and the G9X Mark II have zoom lenses build in. The RX100 has a 28-100mm f/1.8-4.9 optic and the G9X Mark II offers a 28-84mm f/2.0-4.9 (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 RX100 offers the faster maximum aperture.
The G9X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 was succeeded by the Sony RX100 II.
So how do things add up? Is the Sony RX100 better than the Canon G9 X Mark II or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Sony Cyber-shot DSC-RX100:
- More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
- Faster burst: Shoots at higher frequency (10 vs 8.2 flaps/sec) to capture the decisive moment.
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Longer lasting: Can take more shots (330 versus 235) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in June 2012).
Reasons to prefer the Canon PowerShot G9 X Mark II:
- Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
- Less heavy: Has a lower weight (by 34g or 14 percent) and is thus easier to take along.
- More affordable: Was released into a lower priced segment (18 percent cheaper at launch).
- More modern: Reflects 4 years and 7 months of technical progress since the RX100 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the RX100 emerges as the winner of the contest (6 : 4 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 specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the RX100 or the G9X Mark II handle or perform in practice. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
