Canon M10 versus Canon M3

The Canon EOS M10 and the Canon EOS M3 are two digital cameras that were officially introduced, respectively, in October 2015 and February 2015. Both the M10 and the M3 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. The M10 has a resolution of 17.9 megapixel, whereas the M3 provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon M10 vs Canon M3

The physical size and weight of the Canon M10 and the Canon M3 are illustrated 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 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 M10 – 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 (4 percent) than the Canon M10. Moreover, the M3 is markedly heavier (22 percent) than the M10. In this context, it is worth noting that neither the M10 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.

Concerning battery life, the M10 gets 255 shots out of its LP-E12 battery, while the M3 can take 250 images on a single charge of its LP-E17 power pack.

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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M10 was launched at a markedly lower price (by 27 percent) than the M3, which puts it into a different market segment. 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.


Sensor comparison: Canon M10 vs Canon M3

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 more expensive and 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.

Sensor size

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 M10. 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 M10). Moreover, it should be noted, that the M10 is a somewhat more recent model (by 8 months) than the M3, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

Sensor resolution

For most 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 M3 has a markedly higher DXO score than the M10 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.4 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison: Canon M10 vs Canon M3

Beyond body and sensor, cameras can and do differ across a range of features. The M10 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 following table reports on some other key feature differences and similarities of the Canon M10, the Canon M3, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the M10 and the M3 have been discontinued, but can regularly be found used on eBay. The M3 was replaced by the Canon M6, while the M10 was followed by the Canon M100.

Review summary: Canon M10 vs Canon M3

So what is the bottom line? Is there a clear favorite between the Canon M10 and the Canon M3? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon EOS M10:

  • Less heavy: Is lighter (by 65g or 18 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 8 months after the M3).

Arguments in favor 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.
  • Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the M3 comes out slightly ahead of the M10 (4 : 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.

M10 03:04 M3

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the M10 and the M3 in practical situations. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular 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 are only valid when refering to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
