Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon G1 X and the Canon T2i. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T2i is notably larger (33 percent) than the Canon G1 X. In this context, it is worth noting that neither the G1X nor the T2i are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X 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 G1X gets 250 shots out of its Canon NB-10L battery, while the T2i can take 440 images on a single charge of its Canon LP-E8 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.

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. 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Canon T2i an APS-C sensor. The sensor area in the T2i is 27 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 1.6. The sensor in the G1X has a native 4:3 aspect ratio, while the one in the T2i offers a 3:2 aspect.

In terms of chip-set technology, the G1X uses a more advanced image processing engine (DIGIC 5) than the T2i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.

With 17.9MP, the T2i offers a higher resolution than the G1X (14.2MP), but the T2i nevertheless has marginally larger individual pixels (pixel pitch of 4.31μm versus 4.30μm for the G1X) due to its larger sensor. However, the G1X is a somewhat more recent model (by 1 year and 11 months) than the T2i, 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 T2i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T2i for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon G1 X are 21.8 x 16.3 inches or 55.3 x 41.5 cm for good quality, 17.4 x 13.1 inches or 44.2 x 33.2 cm for very good quality, and 14.5 x 10.9 inches or 36.8 x 27.6 cm for excellent quality prints.

The Canon PowerShot G1 X has a native sensitivity range from ISO 100 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 T2i has a markedly higher DXO score than the G1X (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 0.7 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the T2i provides a faster frame rate than the G1X. It can shoot movie footage at 1080/30p, while the G1X is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The G1X and the T2i are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The following table reports on some other key feature differences and similarities of the Canon G1 X, the Canon T2i, and comparable cameras.

Concerning the storage of imaging data, both the G1X and the T2i write their files to SDXC cards.

Connectivity comparison

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 G1 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 T2i has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G1X does not feature such a mic input.

Both the G1X and the T2i have been discontinued, but can regularly be found used on ebay. The T2i was replaced by the Canon T3i, while the G1X was followed by the Canon G1X Mark II. Further information on the features and operation of the G1X and T2i can be found, respectively, in the Canon G1 X Manual (free pdf) or the online Canon T2i Manual.

Review summary

So what is the bottom line? Is the Canon G1 X better than the Canon T2i or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon PowerShot G1 X:

• Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 4).
• 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.
• Ready to shoot: Comes with a built-in lens, while the T2i requires a separate lens.
• More compact: Is smaller (117x81mm vs 129x98mm) and thus needs less room in the bag.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More modern: Is somewhat more recent (announced 1 year and 11 months after the T2i).

Arguments in favor of the Canon EOS Rebel T2i:

• More detail: Has more megapixels (17.9 vs 14.2MP), which boosts linear resolution by 15%.
• Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
• Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• Faster burst: Shoots at higher frequency (3.7 vs 1.9 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (440 versus 250) out of a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in February 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the T2i emerges as the winner of the match-up (10 : 7 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 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 G1 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G1X or the T2i. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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 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.
