Canon G9 X Mark II versus Canon SL1

The Canon PowerShot G9 X Mark II and the Canon EOS Rebel SL1 (labelled Canon 100D in some countries) are two digital cameras that were announced, respectively, in January 2017 and March 2013. The G9X Mark II is a fixed lens compact, while the SL1 is a DSLR. The cameras are based on an one-inch (G9X Mark II) and an APS-C sensor. The G9X Mark II has a resolution of 20 megapixel, whereas the SL1 provides 17.9 MP.

Body comparison

An illustration of the physical size and weight of the Canon G9 X Mark II and the Canon SL1 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 SL1 is considerably larger (87 percent) than the Canon G9 X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the SL1 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 SL1 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 SL1 and their specifications in the Canon EF Lens Catalog.

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 lower price than the SL1, 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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G9 X Mark II features an one-inch sensor and the Canon SL1 an APS-C sensor. The sensor area in the SL1 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.

Sensor size

Despite having a smaller sensor, the Canon G9 X Mark II offers a higher resolution of 20 megapixel, compared with 17.9 MP of the Canon SL1. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.31μm for the SL1). However, it should be noted that the G9X Mark II is much more recent (by 3 years and 9 months) than the SL1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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, but the G9X Mark II provides a higher frame rate than the SL1. It can shoot video footage at 1080/60p, while the SL1 is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the SL1 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 following table reports on some other key feature differences and similarities of the Canon G9 X Mark II, the Canon SL1, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The G9X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the SL1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the SL1 was succeeded by the Canon SL2.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Canon G9 X Mark II and the Canon G9 X Mark II? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon PowerShot G9 X Mark II:

  • More detail: Offers more megapixels (20 vs 17.9MP) with a 6% higher linear resolution.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • Faster burst: Shoots at higher frequency (8.2 vs 4.9 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a build-in lens, while the SL1 requires a separate lens.
  • More compact: Is smaller (98x58mm vs 117x91mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the SL1).
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 3 years and 9 months of technical progress since the SL1 launch.

Arguments in favor of the Canon EOS Rebel SL1:

  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • 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 (380 versus 235) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in March 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the G9X Mark II emerges as the winner of the contest (9 : 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.

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 G9X Mark II or the SL1 handle or perform in practice. 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. This is why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
