Canon G1 X Mark II vs SX420
The Canon PowerShot G1 X Mark II and the Canon PowerShot SX420 IS are two digital cameras that were announced, respectively, in February 2014 and January 2016. Both the G1X Mark II and the SX420 are fixed lens compact cameras that are based on an 1.5-inch (G1X Mark II) and a 1/2.3-inch (SX420) sensor. The G1X Mark II has a resolution of 13 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 PowerShot G1 X Mark II 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 G1 X Mark II and the Canon SX420. 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 width, height and depth measures are rounded to the nearest millimeter.
The SX420 can be obtained in two different colors (black, red), while the G1X Mark II 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 notably smaller (16 percent) than the Canon G1 X Mark II. Moreover, the SX420 is substantially lighter (41 percent) than the G1X Mark II. In this context, it is worth noting that neither the G1X Mark II nor the SX420 are weather-sealed.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX420 was launched at a markedly lower price (by 63 percent) than the G1X Mark II, 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.
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 G1 X Mark II features an 1.5-inch sensor and the Canon SX420 a 1/2.3-inch sensor. The sensor area in the SX420 is 89 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
In terms of chip-set technology, the G1X Mark II uses a more advanced image processing engine (DIGIC 6) than the SX420 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the SX420 offers a higher resolution of 19.9 megapixels, compared with 13 MP of the G1X Mark II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.19μm versus 4.49μm for the G1X Mark II). However, it should be noted that the SX420 is a somewhat more recent model (by 1 year and 10 months) than the G1X Mark II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. 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 SX420 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX420 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Canon G1 X Mark II are 20.8 x 15.6 inches or 52.8 x 39.6 cm for good quality, 16.6 x 12.5 inches or 42.3 x 31.7 cm for very good quality, and 13.9 x 10.4 inches or 35.2 x 26.4 cm for excellent quality prints.
The Canon PowerShot G1 X Mark II has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon PowerShot SX420 IS are ISO 100 to ISO 1600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 G1X Mark II 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. The G1X Mark II 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 G1X Mark II can be equipped with an optional viewfinder – the EVF-DC1. The table below summarizes some of the other core capabilities of the Canon G1 X Mark II and Canon SX420 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark II has a touchscreen, while the SX420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G1X Mark II 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 G1 X Mark II 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.
Both the G1X Mark II and the SX420 have zoom lenses built in. The G1X Mark II has a 24-120mm f/2.0-3.9 optic and the SX420 offers a 24-1008mm f/3.5-6.6 (focal lengths in full frame equivalent terms). Hence, the G1X Mark II and SX420 provide the same view at the wide-angle end, but the SX420 has more tele-photo reach at the long end. The G1X Mark II offers the faster maximum aperture.
Concerning the storage of imaging data, both the G1X Mark II and the SX420 write their files to SDXC cards. The G1X Mark II 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 G1 X Mark II 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 G1X Mark II 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 G1X Mark II and the SX420 have been discontinued, but can regularly be found used on eBay. The G1X Mark II was replaced by the Canon G1 X Mark III, 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 is the bottom line? Which of the two cameras – the Canon G1 X Mark II or the Canon SX420 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot G1 X Mark II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.

- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- More compact: Is smaller (104x69mm vs 116x74mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 228g or 41 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 10 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the G1X Mark II is the clear winner of the match-up (19 : 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 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 G1 X Mark II and the Canon SX420 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 incomplete and does no justice, for example, to the way the G1X Mark II or the SX420 perform in practice. 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 expert reviews 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
