Canon G1 X vs T7
The Canon PowerShot G1 X and the Canon EOS Rebel T7 (labelled Canon 2000D in some countries) are two digital cameras that were revealed to the public, respectively, in January 2012 and February 2018. The G1X is a fixed lens compact, while the T7 is a DSLR. The cameras are based on an 1.5-inch (G1X) and an APS-C (T7) sensor. The G1X has a resolution of 14.2 megapixels, whereas the T7 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 G1 X and the Canon EOS Rebel T7? 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 G1 X and the Canon T7 is provided 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T7 is notably larger (37 percent) than the Canon G1 X. In this context, it is worth noting that neither the G1X nor the T7 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 T7 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 T7 and their specifications in the Canon EF Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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. 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Canon T7 an APS-C sensor. The sensor area in the T7 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 T7 offers a 3:2 aspect.
In terms of chip-set technology, the G1X uses a more advanced image processing engine (DIGIC 5) than the T7 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the T7 offers a higher resolution than the G1X (14.2MP), but the T7 has smaller individual pixels (pixel pitch of 3.72μm versus 4.30μm for the G1X). Yet, the T7 is a much more recent model (by 6 years and 1 month) than the G1X, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon T7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7 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 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 T7 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 T7 provides a faster frame rate than the G1X. It can shoot movie footage at 1080/30p, while the G1X is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a range of features. The G1X and the T7 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 adjacent table lists some of the other core features of the Canon G1 X and Canon T7 along with similar information for a selection of comparators.

It is notable that the T7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G1X does not provide wifi capability.
The T7 is a recent model that features in the current product line-up of Canon. In contrast, the G1X has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the G1X was succeeded by the Canon G1X 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 G1 X and the Canon T7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of 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 T7 requires a separate lens.
- More compact: Is smaller (117x81mm vs 129x101mm) and thus needs less room in the bag.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More heavily discounted: Has been available for much longer (launched in January 2012).
Advantages of the Canon EOS Rebel T7:
- More detail: Has more megapixels (24 vs 14.2MP), which boosts linear resolution by 33%.
- Better image quality: Is equipped with a larger and more technologically advanced sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
- Faster burst: Shoots at higher frequency (3 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 (500 versus 250) out of a single battery charge.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More modern: Reflects 6 years and 1 month of technical progress since the G1X launch.
If the count of individual advantages (bullet points above) is taken as a guide, the T7 is the clear winner of the contest (12 : 7 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.
How about other alternatives? Do the specifications of the Canon G1 X and the Canon T7 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 G1X or the T7 perform in practice. 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.
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.

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
