Sony RX100 V versus Canon G9 X Mark II

The Sony Cyber-shot DSC-RX100 V and the Canon PowerShot G9 X Mark II are two digital cameras that were officially introduced, respectively, in October 2016 and January 2017. Both the RX100 V 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.

Body comparison

An illustration of the physical size and weight of the Sony RX100 V and the Canon G9 X Mark II is provided 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 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 V – represents the basis for the calculations across all the size and weight measures).

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 V, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

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.

Sensor size

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 V 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 2 months) than the RX100 V, and its sensor might have benefitted from technological advances during this time.

Sensor resolution

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. Of the two cameras under review, the RX100 V 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 of lower dynamic range, and 0.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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, but the RX100 V 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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX100 V 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 following table reports on some other key feature differences and similarities of the Sony RX100 V, the Canon G9 X Mark II, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the RX100 V and the G9X Mark II have zoom lenses build in. The RX100 V 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 V offers the faster maximum aperture.

Both the RX100 V and the G9X Mark II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The RX100 V replaced the earlier Sony RX100 IV, while the G9X Mark II followed on from the Canon G9 X.

Summary

So what is the bottom line? Is there a clear favorite between the Sony RX100 V and the Sony RX100 V? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Sony Cyber-shot DSC-RX100 V:

  • 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 (1229k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (24 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.
  • More heavily discounted: Has been on the market for longer (launched in October 2016).

logo checkmark

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 93g 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 (2 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 V is the clear winner of the match-up (9 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX100 V and the G9X Mark II 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
