If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon SL2 is considerably larger (100 percent) than the Canon G9 X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the SL2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X Mark II has a lens built in, whereas the SL2 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the SL2 and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the G9X Mark II gets 235 shots out of its NB-13L battery, while the SL2 can take 650 images on a single charge of its LP-E17 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G9X Mark II was launched at a lower price than the SL2, despite having a lens built in. 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.

 

Sensor comparison: Canon G9 X Mark II vs SL2

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Canon SL2 an APS-C sensor. The sensor area in the SL2 is 186 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G9 X Mark II and Canon SL2 sensor measures

With 24MP, the SL2 offers a higher resolution than the G9X Mark II (20MP), but the SL2 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G9X Mark II) due to its larger sensor. Moreover, the SL2 is a somewhat more recent model (by 5 months) than the G9X Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The SL2 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon PowerShot G9 X Mark II has a native sensitivity range from ISO 125 to ISO 12800 The corresponding ISO settings for the Canon EOS Rebel SL2 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200..

G9X Mark II versus SL2 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the SL2 offers substantially better image quality than the G9X Mark II (overall score 14 points higher). The advantage is based on 1.7 bits higher color depth, 0.9 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Review summary: Canon G9 X Mark II vs SL2

So what is the bottom line? Is there a clear favorite between the Canon G9 X Mark II and the Canon SL2? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon PowerShot G9 X Mark II:

  • Faster burst: Shoots at higher frequency (8.2 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a built-in lens, while the SL2 requires a separate lens.
  • More compact: Is smaller (98x58mm vs 122x93mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the SL2).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been on the market for longer (launched in January 2017).


Arguments in favor of the Canon EOS Rebel SL2:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.7 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (650 versus 235) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More modern: Was introduced somewhat (5 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the SL2 is the clear winner of the contest (15 : 7 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.

G9X Mark II 07:15 SL2

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G9X Mark II and the SL2 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
