Canon G3 X versus Canon G9 X Mark II

The Canon PowerShot G3 X and the Canon PowerShot G9 X Mark II are two digital cameras that were officially introduced, respectively, in June 2015 and January 2017. Both the G3X and the G9X Mark II are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.

Body comparison

The physical size and weight of the Canon G3 X and the Canon G9 X Mark II are illustrated 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the G3X – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G9 X Mark II is considerably smaller (40 percent) than the Canon G3 X. Moreover, the G9X Mark II is substantially lighter (72 percent) than the G3X. It is worth mentioning in this context that the G3X is splash and dust resistant, while the G9X Mark II does not feature any corresponding weather-sealing.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G9X Mark II was launched at a markedly lower price (by 47 percent) than the G3X, 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. 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.

Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixel. This similarity in sensor specs implies that both the G3X and the G9X Mark II have the same pixel density, as well as the same pixel size. It should, however, be noted that the G9X Mark II is a somewhat more recent model (by 1 year and 6 months) than the G3X, and its sensor might have benefitted from technological advances during this time.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. 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

Beyond body and sensor, cameras can and do differ across a range of features. The G3X and the G9X Mark II 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. The table below summarizes some of the other core capabilities of the Canon G3 X and Canon G9 X Mark II in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the G3X and the G9X Mark II have zoom lenses build in. The G3X has a 24-600mm f/2.8-5.6 optic and the G9X Mark II offers a 28-84mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the G3X provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G9X Mark II. The G9X Mark II offers the faster maximum aperture.

Both the G3X and the G9X Mark II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The G9X Mark II replaced the earlier Canon G9 X, while the G3X does not have a direct predecessor.

Summary

So how do things add up? Is the Canon G3 X better than the Canon G9 X Mark II or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon PowerShot G3 X:

  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Can take more shots (300 versus 235) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been on the market for longer (launched in June 2015).

Advantages of the Canon PowerShot G9 X Mark II:

  • Faster burst: Shoots at higher frequency (8.2 vs 5.9 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 compact: Is smaller (98x58mm vs 123x77mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 527g or 72 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G3X emerges as the winner of the contest (8 : 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.

G3X 08:06 G9X Mark II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G3X or the G9X Mark II handle or 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 summarizes the assessments of some of the best known camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
