Body comparison: Canon M3 vs G7X Mark II
An illustration of the physical size and weight of the Canon M3 and the Canon G7 X Mark II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the M3 – represents the basis for the calculations across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G7 X Mark II is notably smaller (14 percent) than the Canon M3. In this context, it is worth noting that neither the M3 nor the G7X Mark II are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens built in, whereas the M3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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: Canon M3 vs G7X Mark II
The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon M3 features an APS-C sensor and the Canon G7 X Mark II an one-inch sensor. The sensor area in the G7X Mark II is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the G7X Mark II uses a more advanced image processing engine (DIGIC 7) than the M3 (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the M3 offers a higher resolution than the G7X Mark II (20MP), but the M3 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.41μm for the G7X Mark II) due to its larger sensor. However, the G7X Mark II is a somewhat more recent model (by 1 year) than the M3, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The M3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS M3 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon PowerShot G7 X Mark II are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 125-25600..
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 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7X Mark II provides a faster frame rate than the M3. It can shoot movie footage at 1080/60p, while the M3 is limited to 1080/30p.
Feature comparison: Canon M3 vs G7X Mark II
Apart from body and sensor, cameras can and do differ across a range of features. The M3 and the G7X Mark II 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 M3 can be equipped with an optional viewfinder – the EVF-DC1.

- Ready to shoot: Has an integrated lens, whereas the M3 necessitates an extra lens.
- More compact: Is smaller (106x61mm vs 111x68mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the M3).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More modern: Was introduced somewhat (1 year) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the M3 is the clear winner of the match-up (12 : 8 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.
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 M3 or the G7X Mark II handle or 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
