Canon G3 X versus Sony RX10

The Canon PowerShot G3 X and the Sony Cyber-shot DSC-RX10 are two digital cameras that were revealed to the public, respectively, in June 2015 and October 2013. Both the G3X and the RX10 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: Canon G3 X vs Sony RX10

An illustration of the physical size and weight of the Canon G3 X and the Sony RX10 is provided 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 width, height and depth measures 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 G3X – 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 Sony RX10 is notably larger (20 percent) than the Canon G3 X. Moreover, the RX10 is markedly heavier (11 percent) than the G3X. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

Concerning battery life, the G3X gets 300 shots out of its NB-10L battery, while the RX10 can take 420 images on a single charge of its NP-FW50 power pack.

Any camera purchase will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G3X was launched at a somewhat lower price (by 23 percent) than the RX10, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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: Canon G3 X vs Sony RX10

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.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors.

Canon G3 X and Sony RX10 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 G3X and the RX10 have the same pixel density, as well as the same pixel size. It should, however, be noted that the G3X is a somewhat more recent model (by 1 year and 8 months) than the RX10, and its sensor might have benefitted from technological advances during this time.

G3X versus RX10 MP

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 consideration, the RX10 has a markedly higher DXO score than the G3X (overall score 6 points higher), which will translate into better image quality. The advantage is based on 1.5 bits higher color depth, 0.3 EV in additional dynamic range, 0.1 stops of reduced 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 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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon G3 X vs Sony RX10

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX10 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon G3 X, the Sony RX10, 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 G3X has a touchscreen, while the RX10 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Both the G3X and the RX10 have zoom lenses build in. The G3X has a 24-600mm f/2.8-5.6 optic and the RX10 offers a 24-200mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

The G3X writes its imaging data to SDXC cards, while the RX10 uses SDXC or Memory Stick PRO Duo cards.

The G3X is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX10 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX10 was succeeded by the Sony RX10 II.

Review summary: Canon G3 X vs Sony RX10

So how do things add up? Which of the two cameras – the Canon G3 X or the Sony RX10 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Canon PowerShot G3 X:

  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1229k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More compact: Is smaller (123x77mm vs 129x88mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 80g or 10 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (23 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 8 months after the RX10).

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX10:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (3200/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (420 versus 300) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in October 2013).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (8 points each). 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 when reflecting and deciding on a new camera.

G3X 08:08 RX10

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G3X or the RX10. 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
