Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Cyber-shot DSC-RX0II and the Canon PowerShot G3 X? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Sony RX0 II and the Canon G3 X 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 dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G3 X is considerably larger (292 percent) than the Sony RX0 II. Moreover, the G3X is substantially heavier (455 percent) than the RX0 II. 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. More than that, the RX0 II is water-proof up to 10m and can, thus, be used for underwater photography.

Concerning battery life, the RX0 II gets 240 shots out of its Sony NP-BJ1 battery, while the G3X can take 300 images on a single charge of its Canon NB-10L power pack. The power pack in the RX0 II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The RX0 II was launched at a markedly lower price (by 30 percent) than the G3X, 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 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.

While the two cameras under review share the same sensor size, the G3X offers a higher resolution of 20 megapixels, compared with 15.4 MP of the RX0 II. This megapixels advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the G3X has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 2.74μm for the RX0 II). Moreover, it should be noted, that the RX0 II is much more recent (by 3 years and 9 months) than the G3X, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

The resolution advantage of the Canon G3 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G3X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Sony RX0 II are 24 x 16 inches or 61 x 40.6 cm for good quality, 19.2 x 12.8 inches or 48.8 x 32.5 cm for very good quality, and 16 x 10.7 inches or 40.6 x 27.1 cm for excellent quality prints.

The Sony Cyber-shot DSC-RX0II has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Canon PowerShot G3 X are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600.

In terms of underlying technology, the RX0 II is build around a CMOS sensor, while the G3X uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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. 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 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, but the RX0 II provides a higher video resolution than the G3X. 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. The RX0 II and the G3X 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. 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 Sony RX0 II, the Canon G3 X, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3X has a touchscreen, while the RX0 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX0 II only has electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The G3X is equipped with a zoom lens, while the RX0 II comes with a built-in prime. The G3X has a 24-600mm f/2.8-5.6 optic and the RX0 II offers a 24mm f/4.0 (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 G3X offers the faster maximum aperture.

The RX0 II writes its imaging data to micro SDXC or Memory Stick Micro cards, while the G3X uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Sony Cyber-shot DSC-RX0II and Canon PowerShot G3 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G3X has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The RX0 II does not feature such an accessory-socket.

The RX0 II is a recent model that features in the current product line-up of Sony. In contrast, the G3X has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the G3X from Canon. Further information on the features and operation of the RX0 II and G3X can be found, respectively, in the Sony RX0 II Manual (free pdf) or the online Canon G3 X Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Sony RX0 II or the Canon G3 X – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Sony Cyber-shot DSC-RX0II:

• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (59x41mm vs 123x77mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 601g or 82 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).
• More modern: Reflects 3 years and 9 months of technical progress since the G3X launch.

Reasons to prefer the Canon PowerShot G3 X:

• More detail: Has more megapixels (20 vs 15.4MP), which boosts linear resolution by 14%.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Larger screen: Has a bigger rear LCD (3.2" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1620k vs 230k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.8 vs f/4.0).
• Longer lasting: Gets more shots (300 versus 240) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More heavily discounted: Has been around for much longer (launched in June 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the G3X is the clear winner of the contest (13 : 9 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 when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Sony RX0 II and the Canon G3 X place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the RX0 II and the G3X 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
