Sony RX100 III versus Canon G7 X Mark II

The Sony Cyber-shot DSC-RX100 III and the Canon PowerShot G7 X Mark II are two digital cameras that were revealed to the public, respectively, in May 2014 and February 2016. Both the RX100 III 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 III vs Canon G7 X Mark II

The side-by-side display below illustrates the physical size and weight of the Sony RX100 III and the Canon G7 X Mark II. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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 III – represents 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 G7 X Mark II is notably larger (9 percent) than the Sony RX100 III. Moreover, the G7X Mark II is markedly heavier (10 percent) than the RX100 III. In this context, it is worth noting that neither the RX100 III nor the G7X Mark II are weather-sealed.

Concerning battery life, the RX100 III gets 320 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 price is, of course, an important factor in any camera decision. 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 G7X Mark II was launched at a somewhat lower price (by 13 percent) than the RX100 III, 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.

 

Sensor comparison: Sony RX100 III vs Canon G7 X Mark II

The size of the sensor inside a digital camera is one of the key determinants 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 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 III 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 III 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 a somewhat more recent model (by 1 year and 9 months) than the RX100 III, 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"). 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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Sony RX100 III vs Canon G7 X Mark II

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX100 III has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X 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 III, the Canon G7 X Mark II, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark II has a touchscreen, while the RX100 III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Both the RX100 III and the G7X Mark II have zoom lenses build in. The RX100 III has a 24-70mm f/1.8-2.8 optic and the G7X Mark II offers a 24-100mm f/1.8-2.8 (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 more tele-photo reach at the long end. Both cameras offer the same maximum aperture.

The RX100 III writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the G7X Mark II uses SDXC cards.

The G7X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 III was succeeded by the Sony RX100 IV.

Review summary: Sony RX100 III vs Canon G7 X Mark II

So what is the bottom line? Is the Sony RX100 III better than the Canon G7 X Mark II or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

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

  • 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).
  • Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (320 versus 265) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in May 2014).

ilogo

Arguments in favor of the Canon PowerShot G7 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.
  • More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 9 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 III comes out slightly ahead of the G7X Mark II (5 : 4 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 before making a decision on a new camera.

RX100 III 05:04 G7X Mark II

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 III and the G7X Mark II in practical situations. 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 why expert reviews are important.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
