Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M3 and the Canon EOS M5? 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon M3 and the Canon M5. 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.

The M3 can be obtained in two different colors (black, white), while the M5 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M5 is notably larger (37 percent) than the Canon M3. Moreover, the M5 is markedly heavier (17 percent) than the M3. In this context, it is worth noting that neither the M3 nor the M5 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. If you want to switch the focus of the display and review another camera pair, you can 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 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 M3 was launched at a markedly lower price (by 31 percent) than the M5, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 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 M5 uses a more advanced image processing engine (DIGIC 7) than the M3 (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixels. This similarity in sensor specs implies that both the M3 and the M5 have the same pixel density, as well as the same pixel size. It should, however, be noted that the M5 is a somewhat more recent model (by 1 year and 7 months) than the M3, and its sensor might have benefitted from technological advances during this time.

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 EOS M5 are ISO 100 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 M5 has a markedly higher DXO score than the M3 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.6 EV in additional dynamic range, and 0.1 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.

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 M5 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

Apart from body and sensor, cameras can and do differ across a range of features. For example, the M5 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M3 relies on live view and the rear LCD for framing. That said, the M3 can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon M3, the Canon M5, and comparable cameras.

Concerning the storage of imaging data, both the M3 and the M5 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.

Connectivity comparison

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 M3 and Canon EOS M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the M3 and the M5 have been discontinued, but can regularly be found used on ebay. The M3 was replaced by the Canon M6, while the M5 does not have a direct successor. Further information on the features and operation of the M3 and M5 can be found, respectively, in the Canon M3 Manual (free pdf) or the online Canon M5 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon M3 and the Canon M5? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS M3:

• More compact: Is smaller (111x68mm vs 116x89mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 61g or 14 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in February 2015).

Arguments in favor of the Canon EOS M5:

• Better image quality: Scores markedly higher (5 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 jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
• Faster burst: Shoots at higher frequency (9 vs 4.2 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (295 versus 250) out of a single battery charge.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Was introduced somewhat (1 year and 7 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the M5 is the clear winner of the contest (11 : 4 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 before making a decision on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 M3 and the Canon M5 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the M3 or the M5 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
