Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX20 was launched at a markedly lower price (by 69 percent) than the G1X Mark III, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G1 X Mark III features an APS-C sensor and the Canon SX20 a 1/2.3-inch sensor. The sensor area in the SX20 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the G1X Mark III has a native 3:2 aspect ratio, while the one in the SX20 offers a 4:3 aspect.

In terms of chip-set technology, the G1X Mark III uses a more advanced image processing engine (DIGIC 7) than the SX20 (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

Canon G1 X Mark III and Canon SX20 sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the SX20 (12MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.53μm for the SX20) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 8 years and 1 month) than the SX20, and its sensor will 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 SX20 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon G1 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X Mark III 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 SX20 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The G1X Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Canon PowerShot SX20 IS are ISO 100 to ISO 3200 (no boost).

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark III has a touchscreen, while the SX20 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The G1X Mark III 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 SX20 does not have a selfie-screen.

The Canon G1 X Mark III 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 III and the SX20 have zoom lenses built in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the SX20 offers a 28-560mm f/2.8-5.7 (focal lengths in full frame equivalent terms). Hence, the G1X Mark III provides a wider angle of view at the short end than the SX20, but less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

The G1X Mark III writes its imaging data to SDXC cards, while the SX20 uses SDHC cards. The G1X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX20 cannot take advantage of Ultra High Speed SD cards.

Review summary

So how do things add up? Which of the two cameras – the Canon G1 X Mark III or the Canon SX20 – 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.


Arguments in favor of the Canon PowerShot G1 X Mark III:

  • More detail: Offers more megapixels (24 vs 12MP) with a 44% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 4).
  • Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 202k dots).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (9 vs 0.7 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More compact: Is smaller (115x78mm vs 123x88mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 201g or 33 percent) and hence easier to carry around.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 8 years and 1 month of technical progress since the SX20 launch.


Reasons to prefer the Canon PowerShot SX20 IS:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in August 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the match-up (25 : 5 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.

G1X Mark III 25:05 SX20

How about other alternatives? Do the specifications of the Canon G1 X Mark III and the Canon SX20 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G1X Mark III or the SX20. 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.

Expert reviews

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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. 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.
