Sony RX100 versus Canon G7 X Mark II

The Sony Cyber-shot DSC-RX100 and the Canon PowerShot G7 X Mark II are two digital cameras that were revealed to the public, respectively, in June 2012 and February 2016. Both the RX100 and the G7X Mark II are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Sony RX100 vs Canon G7 X Mark II

The physical size and weight of the Sony RX100 and the Canon G7 X Mark II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 G7 X Mark II is notably larger (9 percent) than the Sony RX100. Moreover, the G7X Mark II is markedly heavier (33 percent) than the RX100. In this context, it is worth noting that neither the RX100 nor the G7X Mark II are weather-sealed.

Concerning battery life, the RX100 gets 330 shots out of its NP-BX1 battery, while the G7X Mark II can take 265 images on a single charge of its NB-13L power pack.

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.

The camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The RX100 was somewhat cheaper (by 7 percent) than the G7X Mark II at launch, but both cameras fall into the same price category. 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.

 

Sensor comparison: Sony RX100 vs Canon G7 X Mark II

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. 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.

Sony RX100 and Canon G7 X Mark II 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 RX100 and the G7X Mark II have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7X Mark II is much more recent (by 3 years and 8 months) than the RX100, and its sensor will have benefitted from technological advances during this time.

For many cameras, data on sensor performance has been reported by DXO Mark. 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.

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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Sony RX100 vs Canon G7 X Mark II

Beyond body and sensor, cameras can and do differ across a range of features. The RX100 and the G7X 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 G7 X Mark II along with similar information for a selection of comparators.

Both the RX100 and the G7X Mark II have zoom lenses build in. The RX100 has a 28-100mm f/1.8-4.9 optic and the G7X Mark II offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Sony and the same 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 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.

Review summary: Sony RX100 vs Canon G7 X Mark II

So how do things add up? Which of the two cameras – the Sony RX100 or the Canon G7 X Mark II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer 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 flaps/sec) to capture the decisive moment.
  • Less heavy: Is lighter (by 79g or 25 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (330 versus 265) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in June 2012).

ilogo

Arguments in favor of the Canon PowerShot G7 X Mark II:

  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More modern: Reflects 3 years and 8 months of technical progress since the RX100 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the RX100 comes out slightly ahead of the G7X Mark II (5 : 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 before making a camera decision.

RX100 05:04 G7X Mark II

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 RX100 and the G7X 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
