Canon M versus Canon M3
The Canon EOS M and the Canon EOS M3 are two digital cameras that were announced, respectively, in July 2012 and February 2015. Both the Canon M and the M3 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. The Canon M has a resolution of 17.9 megapixel, whereas the M3 provides 24 MP.
The physical size and weight of the Canon M and the Canon M3 are illustrated in the side-by-side display below. 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 Canon M – 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 M3 is somewhat larger (5 percent) than the Canon M. Moreover, the M3 is markedly heavier (23 percent) than the Canon M. In this context, it is worth noting that neither the Canon M nor the M3 are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
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. The Canon M was launched at a somewhat lower price (by 12 percent) than the M3, which makes it more attractive for photographers on a tight budget. 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
While the two cameras under review share the same sensor size, the M3 offers a higher resolution of 24 megapixel, compared with 17.9 MP of the Canon M. This megapixel advantage translates into a 16 percent gain in linear resolution. On the other hand, these sensor specs imply that the M3 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.31μm for the Canon M). However, it should be noted that the M3 is much more recent (by 2 years and 6 months) than the Canon M, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
For most cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the M3 has a markedly higher DXO score than the Canon M (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.6 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. 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 (1080/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The Canon M and the M3 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 adjacent table lists some of the other core features of the Canon M and Canon M3 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the Canon M and the M3 have been discontinued, but can regularly be found used on ebay. The Canon M was replaced by the Canon EOS M3, while the M3 was followed by the Canon M6.
So what conclusions can be drawn? Is the Canon M better than the Canon M3 or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS M:
- Less heavy: Is lighter (by 68g or 19 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced segment (12 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in July 2012).
Advantages of the Canon EOS M3:
- More detail: Has more megapixels (24 vs 17.9MP), which boosts linear resolution by 16%.
- Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More modern: Reflects 2 years and 6 months of technical progress since the Canon M launch.
If the count of relative strengths (bullet points above) is taken as a measure, the M3 is the clear winner of the contest (7 : 3 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the Canon M or the M3. 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. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, 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. 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.
