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-RX1R 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 RX1R 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 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 Sony RX1R II is notably smaller (14 percent) than the Canon G5 X. However, the RX1R II is substantially heavier (44 percent) than the G5X. In this context, it is worth noting that neither the G5X nor the RX1R II are weather-sealed.

Concerning battery life, the G5X gets 210 shots out of its Canon NB-13L battery, while the RX1R II can take 220 images on a single charge of its Sony 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G5X was launched at a markedly lower price (by 76 percent) than the RX1R II, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G5 X features an one-inch sensor and the Sony RX1R II a full frame sensor. The sensor area in the RX1R II is 638 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 42.2MP, the RX1R II offers a higher resolution than the G5X (20MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 2.41μm for the G5X) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the RX1R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony RX1R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Canon G5 X are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

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-RX1R II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the RX1R II offers substantially better image quality than the G5X (overall score 35 points higher). The advantage is based on 4.4 bits higher color depth, 1.6 EV in additional dynamic range, and 2.8 stops in additional 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, 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. The G5X and the RX1R II are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The following table reports on some other key feature differences and similarities of the Canon G5 X, the Sony RX1R II, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The G5X has one, while the RX1R II does not. While the built-in flash of the G5X is not very powerful, it can at times be useful as a fill-in light.

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.

The G5X is equipped with a zoom lens, while the RX1R II comes with a built-in prime. The G5X has a 24-100mm f/1.8-2.8 optic and the RX1R II offers a 35mm f/2.0 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Sony. The G5X offers the faster maximum aperture.

The G5X writes its imaging data to SDXC cards, while the RX1R II uses SDXC or Memory Stick PRO Duo 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 Canon PowerShot G5 X and Sony Cyber-shot DSC-RX1R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX1R II has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G5X does not feature such a mic input.

Both the G5X and the RX1R II have been discontinued, but can regularly be found used on ebay. The G5X was replaced by the Canon G5 X Mark II, while the RX1R II does not have a direct successor. Further information on the features and operation of the G5X and RX1R II can be found, respectively, in the Canon G5 X Manual (free pdf) or the online Sony RX1R II Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G5 X and the Sony RX1R II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot G5 X:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• Faster burst: Shoots at higher frequency (5.9 vs 5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Less heavy: Is lighter (by 154g or 30 percent) and hence easier to carry around.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (76 percent cheaper at launch).

Arguments in favor of the Sony Cyber-shot DSC-RX1R II:

• More detail: Has more megapixels (42.2 vs 20MP), which boosts linear resolution by 45%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (35 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (4.4 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.8 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More compact: Is smaller (113x65mm vs 112x76mm) and will fit more readily into a bag.

If the count of individual advantages (bullet points above) is taken as a guide, the G5X emerges as the winner of the contest (12 : 10 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 Canon G5 X and the Sony RX1R II place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Prime Lens Compact Camera listings 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 says little about, for example, the shooting experience and imaging performance of the G5X and the RX1R II in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
