Canon G3 X vs Sony RX100 II
The Canon PowerShot G3 X and the Sony Cyber-shot DSC-RX100 II are two digital cameras that were announced, respectively, in June 2015 and June 2013. Both the G3X and the RX100 II are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixels.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G3 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.
The side-by-side display below illustrates the physical size and weight of the Canon G3 X and the Sony RX100 II. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 (38 percent) than the Canon G3 X. Moreover, the RX100 II is substantially lighter (62 percent) than the G3X. It is worth mentioning in this context that the G3X is splash and dust resistant, while the RX100 II does not feature any corresponding weather-sealing.
Concerning battery life, the G3X gets 300 shots out of its NB-10L battery, while the RX100 II can take 350 images on a single charge of its NP-BX1 power pack. The power pack in the RX100 II can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. 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 RX100 II was launched at a somewhat lower price (by 25 percent) than the G3X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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.
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 G3X and the RX100 II 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 11 months) than the RX100 II, and its sensor might have benefitted from technological advances during this time.
The Canon PowerShot G3 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.
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. Of the two cameras under consideration, the RX100 II has a markedly higher DXO score than the G3X (overall score 4 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 0.1 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 also of capturing video footage. 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).
Apart from body and sensor, cameras can and do differ across a range of features. The G3X and the RX100 II 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. However, optional viewfinders – the EVF-DC1 for the G3X and the FDA-EV1MK for the RX100 II – are available as accessories. The following table reports on some other key feature differences and similarities of the Canon G3 X, the Sony RX100 II, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G3X 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 G3X has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the RX100 II does not have a selfie-screen.
Both the G3X and the RX100 II have zoom lenses built in. The G3X has a 24-600mm f/2.8-5.6 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, as well as more tele-photo reach at the long end than the Sony. The RX100 II offers the faster maximum aperture.
The G3X writes its imaging data to SDXC cards, while the RX100 II uses SDXC or Memory Stick PRO Duo cards. The G3X 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.
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 G3 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.

It is notable that the G3X has a microphone port, which is missing on the RX100 II. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The G3X is a recent model that features in the current product line-up of Canon. In contrast, the RX100 II has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 II was succeeded by the Sony RX100 III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.
So what is the bottom line? Is there a clear favorite between the Canon G3 X and the Sony RX100 II? Which camera is better? The listing below highlights the relative strengths of the two models.

If the count of relative strengths (bullet points above) is taken as a measure, the G3X comes out slightly ahead of the RX100 II (11 : 10 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 G3 X and the Sony RX100 II place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Travel-Zoom 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G3X or the RX100 II. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 ratings are only valid when referring to cameras in the same category and of the same age. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
