Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX420 IS and the Sony Cyber-shot DSC-RX0II? 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 SX420 and the Sony RX0 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 size dimensions are rounded to the nearest millimeter.
The SX420 can be obtained in two different colors (black, red), while the RX0 II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX0 II is considerably smaller (66 percent) than the Canon SX420. Moreover, the RX0 II is substantially lighter (59 percent) than the SX420. It is noteworthy in this context that the RX0 II is splash and dust-proof, while the SX420 does not feature any corresponding weather-sealing. More than that, the RX0 II is water-proof up to 10m and can, thus, be used for underwater photography.
The power pack in the RX0 II can be charged via the USB port, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. 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 SX420 was launched at a markedly lower price (by 57 percent) than the RX0 II, which puts it into a different market segment. 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.
The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon SX420 features a 1/2.3-inch sensor and the Sony RX0 II an one-inch sensor. The sensor area in the RX0 II is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the SX420 has a native 4:3 aspect ratio, while the one in the RX0 II offers a 3:2 aspect.
Despite having a smaller sensor, the Canon SX420 offers a higher resolution of 19.9 megapixels, compared with 15.4 MP of the Sony RX0 II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.19μm versus 2.74μm for the RX0 II). Moreover, it should be noted that the RX0 II is much more recent (by 3 years and 2 months) than the SX420, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the SX420 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX420 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX420 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 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 Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0II are ISO 80 to ISO 12800 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX0 II provides a better video resolution than the SX420. It can shoot movie footage at 4K/30p, while the Canon is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a range of features. The SX420 and the RX0 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. The adjacent table lists some of the other core features of the Canon SX420 and Sony RX0 II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The SX420 has one, while the RX0 II does not. While the built-in flash of the SX420 is not very powerful, it can at times be useful as a fill-in light.The RX0 II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the SX420 does not have a selfie-screen.
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 SX420 is equipped with a zoom lens, while the RX0 II comes with a built-in prime. The SX420 has a 24-1008mm f/3.5-6.6 optic and the RX0 II offers a 24mm f/4.0 (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. The SX420 offers the faster maximum aperture.
The SX420 writes its imaging data to SDXC cards, while the RX0 II uses micro SDXC or Memory Stick Micro cards. The RX0 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX420 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 SX420 IS and Sony Cyber-shot DSC-RX0II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX0 II has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The SX420 does not feature such a mic input.
Both the SX420 and the RX0 II are recent models that are part of the current product line-up. The SX420 replaced the earlier Canon SX410, while the RX0 II followed on from the Sony RX0. 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? Which of the two cameras – the Canon SX420 or the Sony RX0 II – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the RX0 II is the clear winner of the contest (19 : 9 points). 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 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 SX420 and the Sony RX0 II place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Prime Lens Compact 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 SX420 and the RX0 II in practical situations. 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 following table reports the overall ratings of the cameras as published by some of the major camera 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 above review scores should be interpreted 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
