Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M3 and the Olympus XZ-2? 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 physical size and weight of the Canon M3 and the Olympus XZ-2 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The M3 can be obtained in two different colors (black, white), while the XZ-2 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 Olympus XZ-2 is somewhat smaller (3 percent) than the Canon M3. In this context, it is worth noting that neither the M3 nor the XZ-2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the XZ-2 has a lens built 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The XZ-2 was launched at a lower price than the M3, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon M3 features an APS-C sensor and the Olympus XZ-2 a 1/1.7-inch sensor. The sensor area in the XZ-2 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.4. The sensor in the M3 has a native 3:2 aspect ratio, while the one in the XZ-2 offers a 4:3 aspect.

With 24MP, the M3 offers a higher resolution than the XZ-2 (11.8MP), but the M3 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.91μm for the XZ-2) due to its larger sensor. Moreover, the M3 is a much more recent model (by 2 years and 4 months) than the XZ-2, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

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 Olympus XZ-2 are 19.8 x 14.9 inches or 50.4 x 37.8 cm for good quality, 15.9 x 11.9 inches or 40.3 x 30.2 cm for very good quality, and 13.2 x 9.9 inches or 33.6 x 25.2 cm for excellent quality prints.

The M3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

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 Olympus XZ-2 are ISO 100 to ISO 12800 (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 review, the M3 provides substantially higher image quality than the XZ-2, with an overall score that is 23 points higher. This advantage is based on 2.4 bits higher color depth, 0.5 EV in additional dynamic range, and 2.4 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

Apart from body and sensor, cameras can and do differ across a variety of features. The M3 and the XZ-2 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. However, optional viewfinders – the EVF-DC1 for the M3 and the VF-2 for the XZ-2 – are available as accessories. The adjacent table lists some of the other core features of the Canon M3 and Olympus XZ-2 along with similar information for a selection of comparators.

The Olympus XZ-2 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the M3 and the XZ-2 write their files to SDXC cards. The M3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the XZ-2 cannot take advantage of Ultra High Speed SD cards.

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 Olympus XZ-2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M3 has a microphone port, which is missing on the XZ-2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the M3 and the XZ-2 have been discontinued, but can regularly be found used on ebay. The M3 was replaced by the Canon M6, while the XZ-2 does not have a direct successor. Further information on the features and operation of the M3 and XZ-2 can be found, respectively, in the Canon M3 Manual (free pdf) or the online Olympus XZ-2 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon M3 or the Olympus XZ-2 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS M3:

• More detail: Offers more megapixels (24 vs 11.8MP) with a 45% higher linear resolution.
• Better image quality: Scores substantially higher (23 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.4 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (2.4 stops ISO advantage).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 2 years and 4 months of technical progress since the XZ-2 launch.

Arguments in favor of the Olympus XZ-2:

• Faster burst: Shoots at higher frequency (5 vs 4.2 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has an integrated lens, whereas the M3 necessitates an extra lens.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the M3).
• Longer lasting: Gets more shots (340 versus 250) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been around for much longer (launched in September 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the M3 is the clear winner of the match-up (14 : 8 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 M3 and the Olympus XZ-2 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M3 or the XZ-2. 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 where reviews by experts come in. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
