Canon 5DS R vs SX420
The Canon EOS 5DS R and the Canon PowerShot SX420 IS are two digital cameras that were announced, respectively, in February 2015 and January 2016. The 5DS R is a DSLR, while the SX420 is a fixed lens compact. The cameras are based on a full frame (5DS R) and a 1/2.3-inch (SX420) sensor. The 5DS R has a resolution of 50.3 megapixels, whereas the SX420 provides 19.9 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 EOS 5DS R and the Canon PowerShot SX420 IS? 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 5DS R and the Canon SX420. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The SX420 can be obtained in two different colors (black, red), while the 5DS R 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 Canon SX420 is considerably smaller (59 percent) than the Canon 5DS R. It is worth mentioning in this context that the 5DS R is splash and dust resistant, while the SX420 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX420 has a lens built in, whereas the 5DS R is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 5DS R and their specifications in the Canon EF Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 lower price than the 5DS R, despite having a lens built in. 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.
The size of the imaging sensor is a crucial determinant 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 5DS R features a full frame sensor and the Canon SX420 a 1/2.3-inch sensor. The sensor area in the SX420 is 97 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 5.6. The sensor in the 5DS R has a native 3:2 aspect ratio, while the one in the SX420 offers a 4:3 aspect.
With 50.3MP, the 5DS R offers a higher resolution than the SX420 (19.9MP), but the 5DS R nevertheless has larger individual pixels (pixel pitch of 4.14μm versus 1.19μm for the SX420) due to its larger sensor. However, the SX420 is a somewhat more recent model (by 10 months) than the 5DS R, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. 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 Canon 5DS R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5DS R for good quality output (200 dots per inch) amounts to 43.4 x 29 inches or 110.3 x 73.6 cm, for very good quality (250 dpi) 34.8 x 23.2 inches or 88.3 x 58.8 cm, and for excellent quality (300 dpi) 29 x 19.3 inches or 73.6 x 49 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 EOS 5DS R has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-12800. The corresponding ISO settings for the Canon PowerShot SX420 IS are ISO 100 to ISO 1600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 5DS R provides a higher video resolution than the SX420. It can shoot video footage at 1080/30p, while the SX420 is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 5DS R has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the SX420 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 5DS R and Canon SX420 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 5DS R, but is missing on the SX420 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The Canon 5DS R 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 5DS R writes its imaging data to Compact Flash or SDXC cards, while the SX420 uses SDXC cards. The 5DS R features dual card slots, which can be very useful in case a memory card fails. In contrast, the SX420 only has one slot. The 5DS R 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 EOS 5DS R and Canon PowerShot SX420 IS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5DS R has a hotshoe, while the SX420 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Canon 5DS R (unlike the SX420) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The 5DS R is a recent model that features in the current product line-up of Canon. In contrast, the SX420 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the SX420 was succeeded 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 website.
So how do things add up? Is there a clear favorite between the Canon 5DS R and the Canon SX420? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of relative strengths (bullet points above) is taken as a measure, the 5DS R is the clear winner of the match-up (23 : 9 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 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 5DS R and the Canon SX420 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 5DS R or the SX420. 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 adjacent summary-table relays the overall verdicts of several of the most popular camera 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
