Canon G9 X versus Canon T6i

The Canon PowerShot G9 X and the Canon EOS Rebel T6i (labelled Canon 750D in some countries) are two digital cameras that were officially introduced, respectively, in October 2015 and February 2015. The G9X is a fixed lens compact, while the T6i is a DSLR. The cameras are based on an one-inch (G9X) and an APS-C sensor. The G9X has a resolution of 20 megapixel, whereas the T6i provides 24 MP.

Body comparison

An illustration of the physical size and weight of the Canon G9 X and the Canon T6i is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 – the G9X – 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 T6i is considerably larger (135 percent) than the Canon G9 X. In this context, it is worth noting that neither the G9X nor the T6i are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X has a lens build in, whereas the T6i 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 T6i 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 was launched at a lower price than the T6i, 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 G9 X features an one-inch sensor and the Canon T6i an APS-C sensor. The sensor area in the T6i 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

With 24MP, the T6i offers a higher resolution than the G9X (20MP), but the T6i nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G9X) due to its larger sensor. However, the G9X is a somewhat more recent model (by 8 months) than the T6i, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

G9X versus T6i MP
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"). Of the two cameras under consideration, the T6i has a markedly higher DXO score than the G9X (overall score 8 points higher), which will translate into better image quality. The advantage is based on 1.2 bits higher color depth, 0.3 EV of lower dynamic range, and 0.9 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture 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. For example, the T6i has an optical viewfinder, which can be very useful 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 G9 X and Canon T6i 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 G9X and the T6i have been discontinued, but can regularly be found used on ebay. The T6i was replaced by the Canon T7i, while the G9X was followed by the Canon G9 X Mark II.

Summary

So what conclusions can be drawn? Which of the two cameras – the Canon G9 X or the Canon T6i – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon PowerShot G9 X:

  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a build-in lens, while the T6i requires a separate lens.
  • More compact: Is smaller (98x58mm vs 132x101mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the T6i).
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Is somewhat more recent (announced 8 months after the T6i).

Reasons to prefer the Canon EOS Rebel T6i:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.2 bits more color depth).
  • Better low-light sensitivity: Can shoot in dim conditions (0.9 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 (440 versus 220) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the T6i is the clear winner of the contest (10 : 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.

G9X 06:10 T6i

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 and the T6i in practical situations. 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 full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. 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.
