Canon SX420 vs Sony RX1R
The Canon PowerShot SX420 IS and the Sony Cyber-shot DSC-RX1R are two digital cameras that were revealed to the public, respectively, in January 2016 and June 2013. Both the SX420 and the RX1R are fixed lens compact cameras that are based on a 1/2.3-inch (SX420) and a full frame (RX1R) sensor. The Canon has a resolution of 19.9 megapixels, whereas the Sony provides 24 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-RX1R? 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 RX1R. 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 size dimensions are rounded to the nearest millimeter.
The SX420 can be obtained in two different colors (black, red), while the RX1R 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 RX1R is somewhat larger (2 percent) than the Canon SX420. Moreover, the RX1R is substantially heavier (48 percent) than the SX420. In this context, it is worth noting that neither the SX420 nor the RX1R are weather-sealed.
Concerning battery life, the SX420 gets 195 shots out of its NB-11LH battery, while the RX1R can take 270 images on a single charge of its NP-BX1 power pack. The power pack in the RX1R can be charged via the USB port, 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 SX420 was launched at a markedly lower price (by 89 percent) than the RX1R, 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. 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 RX1R a full frame sensor. The sensor area in the RX1R is 2957 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.0. The sensor in the SX420 has a native 4:3 aspect ratio, while the one in the RX1R offers a 3:2 aspect.
With 24MP, the RX1R offers a higher resolution than the SX420 (19.9MP), but the RX1R nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 1.19μm for the SX420) due to its larger sensor. However, the SX420 is a much more recent model (by 2 years and 6 months) than the RX1R, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Sony RX1R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon SX420 are 25.8 x 19.3 inches or 65.4 x 49.1 cm for good quality, 20.6 x 15.5 inches or 52.3 x 39.3 cm for very good quality, and 17.2 x 12.9 inches or 43.6 x 32.7 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-RX1R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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, but the RX1R provides a better video resolution than the SX420. It can shoot movie footage at 1080/60p, while the Canon is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a variety of features. The SX420 and the RX1R 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. That said, the RX1R can be equipped with an optional viewfinder – the FDA-EV1MK. The table below summarizes some of the other core capabilities of the Canon SX420 and Sony RX1R in connection with corresponding information for a sample of similar cameras.

The SX420 is equipped with a zoom lens, while the RX1R comes with a built-in prime. The SX420 has a 24-1008mm f/3.5-6.6 optic and the RX1R 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 RX1R offers the faster maximum aperture.
The SX420 writes its imaging data to SDXC cards, while the RX1R 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-RX1R 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 RX1R does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the SX420 and the RX1R have been discontinued, but can regularly be found used on eBay. The RX1R was replaced by the Sony RX1R 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 conclusions can be drawn? Which of the two cameras – the Canon SX420 or the Sony RX1R – 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.
Advantages of the Canon PowerShot SX420 IS:

If the count of relative strengths (bullet points above) is taken as a measure, the RX1R is the clear winner of the contest (15 : 7 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 SX420 and the Sony RX1R 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the SX420 or the RX1R perform in practice. 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 (amateurphotographer [AP], cameralabs [CL], 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
