Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G9 X Mark II and the Canon EOS M100? 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 G9 X Mark II and the Canon M100 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 width, height and depth dimensions are rounded to the nearest millimeter.

The G9X Mark II can be obtained in two different colors (black, silver), while the M100 is also available in two color-versions, but different ones (black, white).

Comparison G9X Mark II or M100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M100 is notably larger (27 percent) than the Canon G9 X Mark II. In this context, it is worth noting that neither the G9X Mark II nor the M100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G9X Mark II has a lens built in, whereas the M100 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 G9X Mark II gets 235 shots out of its NB-13L battery, while the M100 can take 295 images on a single charge of its LP-E12 power pack. The power pack in the G9X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.

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 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. 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 Mark II features an one-inch sensor and the Canon M100 an APS-C sensor. The sensor area in the M100 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.

Canon G9 X Mark II and Canon M100 sensor measures

With 24MP, the M100 offers a higher resolution than the G9X Mark II (20MP), but the M100 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G9X Mark II) due to its larger sensor. Moreover, the M100 is a somewhat more recent model (by 7 months) than the G9X Mark II, and its sensor might 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 M100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M100 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 G9 X Mark II 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 M100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon PowerShot G9 X Mark II has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Canon EOS M100 are ISO 100 to ISO 25600 (no boost).

G9X Mark II versus M100 MP

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 M100 offers substantially better image quality than the G9X Mark II (overall score 13 points higher). The advantage is based on 1.6 bits higher color depth, 0.4 EV in additional dynamic range, and 1.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

The M100 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the G9X Mark II does not have a selfie-screen.

The Canon G9 X Mark II 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 Mark II and the M100 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 G9 X Mark II and Canon EOS M100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The G9X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the M100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the M100 was succeeded by the Canon M200. 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 how do things add up? Is the Canon G9 X Mark II better than the Canon M100 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Canon PowerShot G9 X Mark II:

  • Faster burst: Shoots at higher frequency (8.2 vs 6.1 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Has a lens built-in, whereas the M100 requires a separate lens.
  • More compact: Is smaller (98x58mm vs 108x67mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a built-in lens (unlike the M100).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • More heavily discounted: Has been on the market for longer (launched in January 2017).


Arguments in favor of the Canon EOS M100:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • Better low-light sensitivity: Can shoot in dim conditions (1.3 stops ISO advantage).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (295 versus 235) out of a single battery charge.
  • More modern: Was introduced somewhat (7 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the M100 is the clear winner of the contest (11 : 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 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.

G9X Mark II 07:11 M100

How about other alternatives? Do the specifications of the Canon G9 X Mark II and the Canon M100 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G9X Mark II or the M100 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The above review scores should be interpreted 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
