Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G5 X and the Sony Cyber-shot DSC-RX100 II? 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

The physical size and weight of the Canon G5 X and the Sony RX100 II are illustrated in the side-by-side display below. 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 the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 II is considerably smaller (30 percent) than the Canon G5 X. Moreover, the RX100 II is markedly lighter (20 percent) than the G5X. In this context, it is worth noting that neither the G5X nor the RX100 II are weather-sealed.

Concerning battery life, the G5X gets 210 shots out of its NB-13L battery, while the RX100 II can take 350 images on a single charge of its NP-BX1 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 II was somewhat cheaper (by 6 percent) than the G5X at launch, but both cameras fall into the same price category. 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.

Sensor comparison

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. 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.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the G5X and the RX100 II have the same pixel density, as well as the same pixel size. It should, however, be noted that the G5X is much more recent (by 2 years and 3 months) than the RX100 II, and its sensor will have benefitted from technological advances during this time.

The Canon PowerShot G5 X has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 II are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Of the two cameras under consideration, the RX100 II has a markedly higher DXO score than the G5X (overall score 5 points higher), which will translate into better image quality. The advantage is based on 1.1 bits higher color depth, 0.1 EV in additional dynamic range, and -0 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Note: DXO values in italics represent estimates based on sensor size and age.

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

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G5X has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX100 II relies on live view and the rear LCD for framing. That said, the RX100 II can be equipped with an optional viewfinder – the FDA-EV1MK. The adjacent table lists some of the other core features of the Canon G5 X and Sony RX100 II along with similar information for a selection of comparators.

Notes: *) 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 G5X has a touchscreen, while the RX100 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G5 X has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Both the G5X and the RX100 II have zoom lenses built in. The G5X has a 24-100mm f/1.8-2.8 optic and the RX100 II offers a 28-100mm f/1.8-4.9 (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 G5X writes its imaging data to SDXC cards, while the RX100 II uses SDXC or Memory Stick PRO Duo cards. The G5X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the RX100 II cannot take advantage of Ultra High Speed SD cards.

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 Canon PowerShot G5 X and Sony Cyber-shot DSC-RX100 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G5X and the RX100 II have been discontinued, but can regularly be found used on ebay. The RX100 II was replaced by the Sony RX100 III, while the G5X was followed by the Canon G5 X Mark II. Further information on the features and operation of the G5X and RX100 II can be found, respectively, in the Canon G5 X Manual (free pdf) or the online Sony RX100 II Manual.

Review summary

So what is the bottom line? Is the Canon G5 X better than the Sony RX100 II or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot G5 X:

• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 2 years and 3 months of technical progress since the RX100 II launch.

Arguments in favor of the Sony Cyber-shot DSC-RX100 II:

• Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
• More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
• Faster burst: Shoots at higher frequency (10 vs 5.9 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (102x58mm vs 112x76mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 72g or 20 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (350 versus 210) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in June 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (8 points each). 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. 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 Canon G5 X and the Sony RX100 II place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G5X or the RX100 II. 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
