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 X20 was launched at a markedly lower price (by 54 percent) than the G1X Mark III, 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. 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. 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 Fujifilm X20 features a 2/3 sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 472 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 3.9 and 1.5. The sensor in the X20 has a native 4:3 aspect ratio, while the one in the G1X Mark III offers a 3:2 aspect.

With 24MP, the G1X Mark III offers a higher resolution than the X20 (12MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.20μm for the X20) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 4 years and 9 months) than the X20, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the X20 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 Fujifilm X20 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 Fujifilm X20 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon PowerShot G1 X Mark III are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. The X20 uses Fujifilm's X-Trans layout of photosites, while the G1X Mark III employs the more common Bayer array.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), while the X20 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Fujifilm X20 and Canon G1 X Mark III 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 G1X Mark III has a touchscreen, while the X20 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 X20 and the G1X Mark III have zoom lenses built in. The X20 has a 28-112mm f/2.0-2.8 optic and the G1X Mark III offers a 24-72mm f/2.8-5.6 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Fujifilm, but less tele-photo reach at the long end. The X20 offers the faster maximum aperture.

Concerning the storage of imaging data, both the X20 and the G1X Mark III write their files to SDXC cards. The G1X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X20 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 Fujifilm X20 and Canon PowerShot G1 X Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark III offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the X20 does not provide wifi capability.

Both the X20 and the G1X Mark III have been discontinued, but can regularly be found used on ebay. The X20 was replaced by the Fujifilm X30, while the G1X Mark III does not have a direct successor. Further information on the features and operation of the X20 and G1X Mark III can be found, respectively, in the Fujifilm X20 Manual (free pdf) or the online Canon G1 X Mark III Manual.

Review summary

So how do things add up? Is there a clear favorite between the Fujifilm X20 and the Canon G1 X Mark III? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Fujifilm X20:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (12 vs 9 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Less heavy: Is lighter (by 46g or 12 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (270 versus 200) on a single battery charge.
• More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in January 2013).

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

• More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the contest (20 : 10 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 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 Fujifilm X20 and the Canon G1 X Mark III place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the X20 and the G1X Mark III in practical situations. 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 why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

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

The above review scores should be interpreted with care, 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 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.
