Canon G9 X vs T6i
The Canon PowerShot G9 X and the Canon EOS Rebel T6i (labelled Canon 750D in some countries) are two digital cameras that were announced, 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 (T6i) sensor. The G9X has a resolution of 20 megapixels, whereas the T6i provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X and the Canon EOS Rebel T6i? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
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. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The G9X can be obtained in two different colors (black, silver), while the T6i is only available in black.
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 built 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 compare the optics available for the T6i and their specifications in the Canon EF Lens Catalog.
Concerning battery life, the G9X gets 220 shots out of its NB-13L battery, while the T6i can take 440 images on a single charge of its LP-E17 power pack. The power pack in the G9X can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 was launched at a lower price than the T6i, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 more expensive and 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.
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.
The resolution advantage of the Canon T6i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6i for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon G9 X are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The T6i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G9 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Canon EOS Rebel T6i are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
In terms of underlying technology, the G9X is build around a BSI-CMOS sensor, while the T6i uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G9X provides a higher frame rate than the T6i. It can shoot video footage at 1080/60p, while the T6i is limited to 1080/30p.
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 following table reports on some other key feature differences and similarities of the Canon G9 X, the Canon T6i, and comparable cameras.

The Canon G9 X has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the G9X and the T6i write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G9 X and Canon EOS Rebel T6i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T6i has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G9X does not feature such a mic input.
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. Further information on the features and operation of the G9X and T6i can be found, respectively, in the Canon G9 X Manual (free pdf) or the online Canon T6i Manual.
So how do things add up? Is the Canon G9 X better than the Canon T6i or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon PowerShot G9 X:
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with a built-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 built-in lens (unlike the T6i).
- Easier travel charging: Can be conveniently charged via its USB port.
- 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 modern: Is somewhat more recent (announced 8 months after the T6i).
Arguments in favor of 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).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible LCD: Has a 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 (1/4000s vs 1/2000s) 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.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been on the market for longer (launched in February 2015).
If the count of relative strengths (bullet points above) is taken as a measure, the T6i is the clear winner of the contest (14 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon G9 X and the Canon T6i place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G9X or the T6i 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
