Sony RX100 IV versus Canon G9 X Mark II
The Sony Cyber-shot DSC-RX100 IV and the Canon PowerShot G9 X Mark II are two digital cameras that were revealed to the public, respectively, in June 2015 and January 2017. Both the RX100 IV 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.
The side-by-side display below illustrates the physical size and weight of the Sony RX100 IV and the Canon G9 X Mark II. 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 RX100 IV – 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 IV. Moreover, the G9X Mark II is markedly lighter (31 percent) than the RX100 IV. In this context, it is worth noting that neither the RX100 IV nor the G9X Mark II are weather-sealed.

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 markedly lower price (by 47 percent) than the RX100 IV, which puts it into a different market segment. 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 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. 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 IV 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 a somewhat more recent model (by 1 year and 6 months) than the RX100 IV, and its sensor might 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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the RX100 IV has a notably higher overall DXO score than the G9X Mark II (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.1 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX100 IV provides a higher video resolution than the G9X Mark II. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX100 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G9X Mark II relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Sony RX100 IV and Canon G9 X Mark II 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 RX100 IV and the G9X Mark II have zoom lenses build in. The RX100 IV has a 24-70mm f/1.8-2.8 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 provides a wider angle of view at the short end than the Canon, but less tele-photo reach at the long end. The RX100 IV 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 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 V.
So what is the bottom line? Is there a clear favorite between the Sony RX100 IV and the Sony RX100 IV? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Sony Cyber-shot DSC-RX100 IV:
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More detailed LCD: Has a higher resolution rear screen (1228k vs 1040k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (16 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).
- Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
- Longer lasting: Can take more shots (280 versus 235) on a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in June 2015).
Arguments in favor of the Canon PowerShot G9 X Mark II:
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Less heavy: Has a lower weight (by 92g or 31 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 6 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the RX100 IV is the clear winner of the match-up (10 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the RX100 IV 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
