Canon M vs 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 megapixels, whereas the M3 provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M and the Canon EOS M3? 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.
An illustration of the physical size and weight of the Canon M and the Canon M3 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.
Both cameras are available in two different colors (black, white).
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 and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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. 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 are more costly to manufacture and tend to lead to bigger and heavier cameras 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.
Technology-wise, the M3 uses a more advanced image processing engine (DIGIC 6) than the Canon M (DIGIC V), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the M3 offers a higher resolution of 24 megapixels, compared with 17.9 MP of the Canon M. This megapixels 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.
The resolution advantage of the Canon M3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M3 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 M are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
The Canon EOS M has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The Canon EOS M3 offers exactly the same ISO settings.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
| DXO |
|7.||Canon G7 X||1-inch||20.0||5472||3648||1080/60p||23.0||12.7||556||71|
|11.||Panasonic GF6||Four Thirds||15.8||4592||3448||1080/60i||20.7||10.6||622||54|

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. That said, the M3 can be equipped with an optional viewfinder – the EVF-DC1. 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.

One difference between the cameras concerns the presence of an on-board flash. The M3 has one, while the Canon M does not. While the built-in flash of the M3 is not very powerful, it can at times be useful as a fill-in light.The M3 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 Canon M does not have a selfie-screen.
Concerning the storage of imaging data, both the Canon M and the M3 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.
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 EOS M and Canon EOS M3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
| NFC |

It is notable that the M3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the Canon M does not provide wifi capability.
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. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Is there a clear favorite between the Canon M and the Canon M3? Which camera is better? 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).
- Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC V).
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- 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.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More modern: Reflects 2 years and 6 months of technical progress since the Canon M launch.
If the number of relative strengths (bullet points above) is taken as a guide, the M3 is the clear winner of the contest (12 : 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 before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon M and the Canon M3 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 Canon M or the M3 perform in practice. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
