Canon G9 X vs T2i
The Canon PowerShot G9 X and the Canon EOS Rebel T2i (labelled Canon 550D in some countries) are two digital cameras that were officially introduced, respectively, in October 2015 and February 2010. The G9X is a fixed lens compact, while the T2i is a DSLR. The cameras are based on an one-inch (G9X) and an APS-C (T2i) sensor. The G9X has a resolution of 20 megapixels, whereas the T2i provides 17.9 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 T2i? 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 side-by-side display below illustrates the physical size and weight of the Canon G9 X and the Canon T2i. 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 T2i 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 T2i is considerably larger (122 percent) than the Canon G9 X. In this context, it is worth noting that neither the G9X nor the T2i 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 T2i 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 T2i 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 T2i can take 440 images on a single charge of its LP-E8 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

|Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. 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 was launched at a lower price than the T2i, 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.
The size of the imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 T2i an APS-C sensor. The sensor area in the T2i 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.
In terms of chip-set technology, the G9X uses a more advanced image processing engine (DIGIC 6) than the T2i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a smaller sensor, the Canon G9 X offers a higher resolution of 20 megapixels, compared with 17.9 MP of the Canon T2i. This megapixels 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 T2i). However, it should be noted that the G9X is much more recent (by 5 years and 8 months) than the T2i, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon G9 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon T2i are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
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 T2i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G9X provides a higher frame rate than the T2i. It can shoot video footage at 1080/60p, while the T2i is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the T2i 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 adjacent table lists some of the other core features of the Canon G9 X and Canon T2i along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9X has a touchscreen, while the T2i has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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 T2i write their files to SDXC cards. The G9X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T2i cannot take advantage of Ultra High Speed SD cards.
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 T2i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9X offers wifi support, while the T2i does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the G9X and the T2i have been discontinued, but can regularly be found used on eBay. The T2i was replaced by the Canon T3i, while the G9X was followed by the Canon G9 X Mark II. 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 how do things add up? Is there a clear favorite between the Canon G9 X and the Canon T2i? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon PowerShot G9 X:

- More heavily discounted: Has been around for much longer (launched in February 2010).
If the count of relative strengths (bullet points above) is taken as a measure, the G9X is the clear winner of the match-up (17 : 8 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 T2i 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 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 and the T2i in practical situations. 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 where reviews by experts come in. 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
