Canon G1 X Mark III versus Canon G9 X

The Canon PowerShot G1 X Mark III and the Canon PowerShot G9 X are two digital cameras that were officially introduced, respectively, in October 2017 and October 2015. Both the G1X Mark III and the G9X are fixed lens compact cameras that are based on an APS-C (G1X Mark III) and an one-inch sensor. The G1X Mark III has a resolution of 24 megapixel, whereas the G9X provides 20 MP.

Body comparison

An illustration of the physical size and weight of the Canon G1 X Mark III and the Canon G9 X is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the G1X Mark III – represents the basis for the calculations across all the size and weight measures).

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9X was launched at a markedly lower price (by 59 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 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. 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 are more costly to manufacture and tent 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 G9 X an one-inch sensor. The sensor area in the G9X is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 24MP, the G1X Mark III offers a higher resolution than the G9X (20MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G9X) due to its larger sensor. Moreover, the G1X Mark III is a somewhat more recent model (by 2 years) than the G9X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G9X relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G1 X Mark III and Canon G9 X in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the G1X Mark III and the G9X have zoom lenses build in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the G9X offers a 28-84mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the G1X Mark III provides a wider angle of view at the short end than the G9X, but less tele-photo reach at the long end. The G9X offers the faster maximum aperture.

The G1X Mark III is a current model that online retailers, such as amazon, will have in stock. In contrast, the G9X has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the G9X was succeeded by the Canon G9 X Mark II.

Summary

So what conclusions can be drawn? Which of the two cameras – the Canon G1 X Mark III or the Canon G9 X – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon PowerShot G1 X Mark III:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (9 vs 6 flaps/sec) to capture the decisive moment.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Reflects 2 years of technical progress since the G9X launch.

Advantages of the Canon PowerShot G9 X:

  • 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.
  • More compact: Is smaller (98x58mm vs 115x78mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 190g or 48 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (59 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in October 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the G1X Mark III emerges as the winner of the contest (8 : 6 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.

G1X Mark III 08:06 G9X

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G1X Mark III or the G9X. 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 summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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.
