Canon SX420 vs T6s
The Canon PowerShot SX420 IS and the Canon EOS Rebel T6s (labelled Canon 760D in some countries) are two digital cameras that were officially introduced, respectively, in January 2016 and February 2015. The SX420 is a fixed lens compact, while the T6s is a DSLR. The cameras are based on a 1/2.3-inch (SX420) and an APS-C (T6s) sensor. The SX420 has a resolution of 19.9 megapixels, whereas the T6s 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 Canon EOS Rebel T6s? 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 Canon T6s is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The SX420 can be obtained in two different colors (black, red), while the T6s 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 T6s is considerably larger (86 percent) than the Canon SX420. In this context, it is worth noting that neither the SX420 nor the T6s are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX420 has a lens built in, whereas the T6s 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 T6s and their specifications in the Canon EF Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 SX420 was launched at a lower price than the T6s, 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Canon T6s an APS-C sensor. The sensor area in the T6s is 1086 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.6. The sensor in the SX420 has a native 4:3 aspect ratio, while the one in the T6s offers a 3:2 aspect.
Technology-wise, the T6s uses a more advanced image processing engine (DIGIC 6) than the SX420 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the T6s offers a higher resolution than the SX420 (19.9MP), but the T6s nevertheless has larger individual pixels (pixel pitch of 3.72μm 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 T6s, and its sensor might 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 resolution advantage of the Canon T6s implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6s 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 T6s has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS Rebel T6s are ISO 100 to ISO 12800, 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 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. 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the T6s provides a better video resolution than the SX420. It can shoot movie footage at 1080/30p, while the SX420 is limited to 720/25p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the T6s 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 adjacent table lists some of the other core features of the Canon SX420 and Canon T6s along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T6s has a touchscreen, while the SX420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The T6s 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.
Concerning the storage of imaging data, both the SX420 and the T6s write their files to SDXC cards. The T6s 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 Canon EOS Rebel T6s and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T6s 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 T6s have been discontinued, but can regularly be found used on eBay. The T6s was replaced by the Canon 77D, 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 website.
So what conclusions can be drawn? Is the Canon SX420 better than the Canon T6s or vice versa? Below is a summary of the relative strengths of each of the two contestants.

- More heavily discounted: Has been on the market for longer (launched in February 2015).
If the count of individual advantages (bullet points above) is taken as a guide, the T6s is the clear winner of the contest (22 : 7 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 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 Canon T6s place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the SX420 and the T6s in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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], 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.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
