Canon SX420 vs Sony RX100
The Canon PowerShot SX420 IS and the Sony Cyber-shot DSC-RX100 are two digital cameras that were officially introduced, respectively, in January 2016 and June 2012. Both the SX420 and the RX100 are fixed lens compact cameras that are based on a 1/2.3-inch (SX420) and an one-inch (RX100) sensor. The Canon has a resolution of 19.9 megapixels, whereas the Sony provides 20 MP.
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 SX420 IS and the Sony Cyber-shot DSC-RX100? 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.
An illustration of the physical size and weight of the Canon SX420 and the Sony RX100 is provided in the side-by-side display below. 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 RX100 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 RX100 is notably smaller (18 percent) than the Canon SX420. Moreover, the RX100 is markedly lighter (26 percent) than the SX420. In this context, it is worth noting that neither the SX420 nor the RX100 are weather-sealed.
Concerning battery life, the SX420 gets 195 shots out of its NB-11LH battery, while the RX100 can take 330 images on a single charge of its NP-BX1 power pack. The power pack in the RX100 can be charged via the USB port, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 SX420 was launched at a markedly lower price (by 54 percent) than the RX100, 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.
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. 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 SX420 features a 1/2.3-inch sensor and the Sony RX100 an one-inch sensor. The sensor area in the RX100 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 RX100 offers a 3:2 aspect.
With 20MP, the RX100 offers a higher resolution than the SX420 (19.9MP), but the RX100 nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.19μm for the SX420) due to its larger sensor. However, the SX420 is a much more recent model (by 3 years and 7 months) than the RX100, and its sensor will have benefitted from technological advances during this time that 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 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-RX100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX100 provides a better video resolution than the SX420. It can shoot movie footage at 1080/60p, while the Canon is limited to 720/25p.
Beyond body and sensor, cameras can and do differ across a range of features. The SX420 and the RX100 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 table below summarizes some of the other core capabilities of the Canon SX420 and Sony RX100 in connection with corresponding information for a sample of similar cameras.

Both the SX420 and the RX100 have zoom lenses built in. The SX420 has a 24-1008mm f/3.5-6.6 optic and the RX100 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 offers the faster maximum aperture.
The SX420 writes its imaging data to SDXC cards, while the RX100 uses SDXC or Memory Stick PRO Duo 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-RX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX420 offers wifi support, while the RX100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the SX420 and the RX100 have been discontinued, but can regularly be found used on eBay. The RX100 was replaced by the Sony RX100 II, while the SX420 was followed by the Canon SX430. 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 SX420 and the Sony RX100? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot SX420 IS:

- More heavily discounted: Has been around for much longer (launched in June 2012).
If the number of relative strengths (bullet points above) is taken as a guide, the RX100 is the clear winner of the contest (14 : 8 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 RX100 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 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 SX420 or the RX100. 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 why hands-on reviews by experts 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
