Canon G15 vs T7

The Canon PowerShot G15 and the Canon EOS Rebel T7 (labelled Canon 2000D in some countries) are two digital cameras that were revealed to the public, respectively, in September 2012 and February 2018. The G15 is a fixed lens compact, while the T7 is a DSLR. The cameras are based on a 1/1.7-inch (G15) and an APS-C (T7) sensor. The G15 has a resolution of 12 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 G15 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.

Body comparison

An illustration of the physical size and weight of the Canon G15 and the Canon T7 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Compare G15 versus T7 top
Comparison G15 or T7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T7 is considerably larger (60 percent) than the Canon G15. In this context, it is worth noting that neither the G15 nor the T7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G15 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.

Concerning battery life, the G15 gets 350 shots out of its NB-10L battery, while the T7 can take 500 images on a single charge of its LP-E10 power pack.

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, just use the right or left arrows in the table to switch to the respective camera.

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. 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 size of the imaging sensor is a crucial determinant 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 G15 features a 1/1.7-inch sensor and the Canon T7 an APS-C sensor. The sensor area in the T7 is 672 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 1.6. The sensor in the G15 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 G15 uses a more advanced image processing engine (DIGIC 5) than the T7 (DIGIC 4+), with benefits for noise reduction, color accuracy, and processing speed.

Canon G15 and Canon T7 sensor measures

With 24MP, the T7 offers a higher resolution than the G15 (12MP), but the T7 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.89μm for the G15) due to its larger sensor. Moreover, the T7 is a much more recent model (by 5 years and 5 months) than the G15, 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 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 G15 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot G15 has a native sensitivity range from ISO 80 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.

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 G15. It can shoot movie footage at 1080/30p, while the G15 is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The G15 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 table below summarizes some of the other core capabilities of the Canon G15 and Canon T7 in connection with corresponding information for a sample of similar cameras.

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 G15 does not provide wifi capability.

The T7 is a recent model that features in the current product line-up of Canon. In contrast, the G15 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G15 was succeeded by the Canon G16. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G15 and the Canon T7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon PowerShot G15:

  • Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 4+).
  • Ready to shoot: Comes with a built-in lens, while the T7 requires a separate lens.
  • More compact: Is smaller (107x76mm vs 129x101mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the T7).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More heavily discounted: Has been available for much longer (launched in September 2012).


Advantages of the Canon EOS Rebel T7:

  • More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
  • 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 2.1 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 350) 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 5 years and 5 months of technical progress since the G15 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the T7 is the clear winner of the contest (12 : 6 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 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.

G15 06:12 T7

How about other alternatives? Do the specifications of the Canon G15 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G15 and the T7 in practical situations. 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

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