Canon G9 X Mark II vs T8i
The Canon PowerShot G9 X Mark II and the Canon EOS Rebel T8i (labelled Canon 850D in some countries) are two digital cameras that were announced, respectively, in January 2017 and February 2020. The G9X Mark II is a fixed lens compact, while the T8i is a DSLR. The cameras are based on an one-inch (G9X Mark II) and an APS-C (T8i) sensor. The G9X Mark II has a resolution of 20 megapixels, whereas the T8i 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 Mark II and the Canon EOS Rebel T8i? 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.
The physical size and weight of the Canon G9 X Mark II and the Canon T8i are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
The G9X Mark II can be obtained in two different colors (black, silver), while the T8i 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 T8i is considerably larger (137 percent) than the Canon G9 X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the T8i 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 T8i 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 T8i 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 T8i can take 800 images on a single charge of its LP-E17 power pack. The power pack in the G9X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G9X Mark II was launched at a lower price than the T8i, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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 T8i an APS-C sensor. The sensor area in the T8i 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.
Technology-wise, the T8i uses a more advanced image processing engine (DIGIC 8) than the G9X Mark II (DIGIC 7), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the T8i offers a higher resolution than the G9X Mark II (20MP), but the T8i 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 T8i is a much more recent model (by 3 years and 1 month) than the G9X Mark II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon T8i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T8i 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 Mark II 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 T8i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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 T8i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
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. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the T8i provides a better video resolution than the G9X Mark II. It can shoot movie footage at 4K/24p, while the G9X Mark II is limited to 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the T8i 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 T8i, and comparable cameras.

The Canon G9 X Mark II and the Canon T8i both have 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 Mark II and the T8i 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 Mark II and Canon EOS Rebel T8i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T8i has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G9X Mark II does not feature such a mic input.
Both the G9X Mark II and the T8i are recent models that are part of the current product line-up. The G9X Mark II replaced the earlier Canon G9 X, while the T8i followed on from the Canon T7i. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Which of the two cameras – the Canon G9 X Mark II or the Canon T8i – has the upper hand? Is one clearly better than the other? 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:
- Ready to shoot: Comes with a built-in lens, while the T8i requires a separate lens.

If the number of relative strengths (bullet points above) is taken as a guide, the T8i is the clear winner of the contest (17 : 8 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. 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the G9X Mark II and the T8i 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 why expert reviews 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], 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
