Canon M6 vs SX420
The Canon EOS M6 and the Canon PowerShot SX420 IS are two digital cameras that were revealed to the public, respectively, in February 2017 and January 2016. The M6 is a mirrorless interchangeable lens camera, while the SX420 is a fixed lens compact. The cameras are based on an APS-C (M6) and a 1/2.3-inch (SX420) sensor. The M6 has a resolution of 24 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 M6 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 physical size and weight of the Canon M6 and the Canon SX420 are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.
The M6 can be obtained in two different colors (black, silver), while the SX420 is also available in two color-versions, but different ones (black, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SX420 is notably smaller (6 percent) than the Canon M6. In this context, it is worth noting that neither the M6 nor the SX420 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 M6 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 M6, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon M6 features an APS-C sensor and the Canon SX420 a 1/2.3-inch sensor. The sensor area in the SX420 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 5.6. The sensor in the M6 has a native 3:2 aspect ratio, while the one in the SX420 offers a 4:3 aspect.
In terms of chip-set technology, the M6 uses a more advanced image processing engine (DIGIC 7) than the SX420 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the M6 offers a higher resolution than the SX420 (19.9MP), but the M6 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.19μm for the SX420) due to its larger sensor. Moreover, the M6 is a somewhat more recent model (by 1 year and 1 month) than the SX420, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 M6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 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 M6 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M6 has a native sensitivity range from ISO 100 to ISO 25600. 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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 M6 provides a higher video resolution than the SX420. It can shoot video footage at 1080/60p, while the SX420 is limited to 720/25p.
Apart from body and sensor, cameras can and do differ across a variety of features. The M6 and the SX420 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 M6 can be equipped with an optional viewfinder – the EVF-DC2. The adjacent table lists some of the other core features of the Canon M6 and Canon SX420 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 M6 has a touchscreen, while the SX420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The M6 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the SX420 does not have a selfie-screen.
The Canon M6 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.
Concerning the storage of imaging data, both the M6 and the SX420 write their files to SDXC cards. The M6 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 M6 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 M6 has a hotshoe, while the SX420 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the M6 and the SX420 have been discontinued, but can regularly be found used on eBay. The SX420 was replaced by the Canon SX430, while the M6 was followed by the Canon M6 Mark II. 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 M6 and the Canon SX420? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Canon EOS M6:
- More detail: Offers more megapixels (24 vs 19.9MP) with a 12% higher linear resolution.

- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Is somewhat more recent (announced 1 year and 1 month after the SX420).
Arguments in favor of the Canon PowerShot SX420 IS:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Ready to shoot: Has an integrated lens, whereas the M6 necessitates an extra lens.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the M6).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been on the market for longer (launched in January 2016).
If the number of relative strengths (bullet points above) is taken as a guide, the M6 is the clear winner of the match-up (23 : 6 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 M6 and the Canon SX420 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 M6 or the SX420. 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 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], 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
