Canon G9 X Mark II versus Canon SL2

The Canon PowerShot G9 X Mark II and the Canon EOS Rebel SL2 (labelled Canon 200D in some countries) are two digital cameras that were officially introduced, respectively, in January 2017 and June 2017. The G9X Mark II is a fixed lens compact, while the SL2 is a DSLR. The cameras are based on an one-inch (G9X Mark II) and an APS-C (SL2) sensor. The G9X Mark II has a resolution of 20 megapixel, whereas the SL2 provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon G9 X Mark II vs Canon SL2

An illustration of the physical size and weight of the Canon G9 X Mark II and the Canon SL2 is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth 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 – the G9X Mark II – represents 100 percent 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 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 build 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 find an overview of optics 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 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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch 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 lower price than the SL2, despite having a lens build 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon G9 X Mark II vs Canon SL2

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 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.

G9X Mark II versus SL2 MP

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"). 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 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 cannot only take still pictures, but also record videos. 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: Canon G9 X Mark II vs Canon SL2

Beyond body and sensor, cameras can and do differ across a range of features. For example, the SL2 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G9X Mark II relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G9 X Mark II and Canon SL2 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the G9X Mark II and the SL2 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 SL2 followed on from the Canon SL1.

Review summary: Canon G9 X Mark II vs Canon SL2

So what conclusions can be drawn? Is the Canon G9 X Mark II better than the Canon SL2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of 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 build-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 build-in lens (unlike the SL2).
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More heavily discounted: Has been on the market for longer (launched in January 2017).


Advantages 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).
  • 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.
  • 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.
  • More modern: Was introduced somewhat (5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the SL2 is the clear winner of the contest (11 : 7 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 before making a camera decision.

G9X Mark II 07:11 SL2

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G9X Mark II or the SL2. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
