Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G7 X and the Canon EOS M6? 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 G7 X and the Canon M6 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 size dimensions are rounded to the nearest millimeter.

The M6 can be obtained in two different colors (black, silver), while the G7X is only available in black.

Comparison G7X or M6 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M6 is notably larger (23 percent) than the Canon G7 X. In this context, it is worth noting that neither the G7X nor the M6 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X has a lens built in, whereas the M6 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the G7X gets 210 shots out of its NB-13L battery, while the M6 can take 295 images on a single charge of its LP-E17 power pack.

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

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.
(1) Number of images that can be taken on a full battery charge according to the CIPA-standard; (2) Official announcement.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G7X was launched at a lower price than the M6, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G7 X features an one-inch sensor and the Canon M6 an APS-C sensor. The sensor area in the M6 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 M6 uses a more advanced image processing engine (DIGIC 7) than the G7X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.

Canon G7 X and Canon M6 sensor measures

With 24MP, the M6 offers a higher resolution than the G7X (20MP), but the M6 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G7X) due to its larger sensor. Moreover, the M6 is a much more recent model (by 2 years and 5 months) than the G7X, 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 M6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M6 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 G7 X 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 M6 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Canon EOS M6 are ISO 100 to ISO 25600 (no boost).

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The G7X and the M6 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the M6 can be equipped with an optional viewfinder – the EVF-DC2. The table below summarizes some of the other core capabilities of the Canon G7 X and Canon M6 in connection with corresponding information for a sample of similar cameras.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

The Canon G7 X and the Canon M6 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 G7X and the M6 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.

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 G7 X and Canon EOS M6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G7X does not feature such a mic input.

Both the G7X and the M6 have been discontinued, but can regularly be found used on eBay. The G7X was replaced by the Canon G7 X Mark II, while the M6 was followed by the Canon M6 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.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G7 X and the Canon M6? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon PowerShot G7 X:

  • Ready to shoot: Has a lens built-in, whereas the M6 requires a separate lens.
  • More compact: Is smaller (103x60mm vs 112x68mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the M6).
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been available for much longer (launched in September 2014).


Reasons to prefer the Canon EOS M6:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • 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 jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • Faster burst: Shoots at higher frequency (9 vs 6.5 flaps/sec) to capture the decisive moment.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (295 versus 210) out of a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 2 years and 5 months of technical progress since the G7X launch.

If the number of relative strengths (bullet points above) is taken as a guide, the M6 is the clear winner of the contest (16 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

G7X 06:16 M6

How about other alternatives? Do the specifications of the Canon G7 X and the Canon M6 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 G7X or the M6. 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.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
