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 revealed to the public, 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.

Body comparison

The physical size and weight of the Sony RX100 and the Canon G9 X Mark II are illustrated 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 dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the RX100 – represents the basis or 100 percent 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.

Sensor comparison

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. 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 associated with larger, more expensive camera bodies 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 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.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 also of capturing video footage. 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).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range 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 adjacent table lists some of the other core features of the Sony RX100 and Canon G9 X Mark II along with similar information for a selection of comparators. 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.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Sony RX100 and the Sony RX100? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor 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).

logo checkmark

Advantages of the Canon PowerShot G9 X Mark II:

  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • 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 relative strengths (bullet points above) is taken as a measure, the RX100 comes out slightly ahead of the G9X Mark II (6 : 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 or the G9X Mark II handle or perform in practice. 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 table below summarizes the assessments of some of the best known camera review sites. The full reviews are available, 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 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, please note that some of the review sites have changed their methodology and reporting over time.
