Canon M3 versus Canon G7 X Mark II
The Canon EOS M3 and the Canon PowerShot G7 X Mark II are two digital cameras that were revealed to the public, respectively, in February 2015 and February 2016. The M3 is a mirrorless interchangeable lens camera, while the G7X Mark II is a fixed lens compact. The cameras are based on an APS-C (M3) and an one-inch sensor. The M3 has a resolution of 24 megapixel, whereas the G7X Mark II provides 20 MP.
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. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 – the M3 – represents the basis or 100 percent 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 build 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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.
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. 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 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.
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.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, 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.
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. The following table reports on some other key feature differences and similarities of the Canon M3, the Canon G7 X Mark II, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

The G7X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the M3 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the M3 was succeeded by the Canon M6.
So how do things add up? Is the Canon M3 better than the Canon G7 X Mark II or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS M3:
- More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
- Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
- Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More heavily discounted: Has been on the market for longer (launched in February 2015).
Reasons to prefer the Canon PowerShot G7 X Mark II:
- Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
- Faster burst: Shoots at higher frequency (8 vs 4.2 flaps/sec) to capture the decisive moment.
- 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 build in (unlike the M3).
- More modern: Was introduced somewhat (1 year) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark II comes out slightly ahead of the M3 (6 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the M3 and the G7X Mark II in practical situations. 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. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.

There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored.
