Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M and the Sony Cyber-shot DSC-RX0? 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 M and the Sony RX0. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The Canon M can be obtained in two different colors (black, white), while the RX0 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 Sony RX0 is considerably smaller (66 percent) than the Canon M. It is noteworthy in this context that the RX0 is splash and dust-proof, while the Canon M does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX0 has a lens built in, whereas the Canon M is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the Canon M gets 230 shots out of its Canon LP-E12 battery, while the RX0 can take 240 images on a single charge of its Sony NP-BJ1 power pack. The power pack in the RX0 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon M features an APS-C sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 is 65 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 17.9MP, the Canon M offers a higher resolution than the RX0 (15.4MP), but the Canon M nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 2.74μm for the RX0) due to its larger sensor. However, the RX0 is a much more recent model (by 5 years and 1 month) than the Canon M, 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 M implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon M for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Sony RX0 are 24 x 16 inches or 61 x 40.6 cm for good quality, 19.2 x 12.8 inches or 48.8 x 32.5 cm for very good quality, and 16 x 10.7 inches or 40.6 x 27.1 cm for excellent quality prints.

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

The Canon EOS M 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 Sony Cyber-shot DSC-RX0 are ISO 125 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 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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX0 provides a faster frame rate than the Canon M. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The Canon M and the RX0 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 M, the Sony RX0, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Canon M has a touchscreen, while the RX0 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX0 only has electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Canon M writes its imaging data to SDXC cards, while the RX0 uses micro SDXC or Memory Stick Micro 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 M and Sony Cyber-shot DSC-RX0 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Canon M has a hotshoe, while the RX0 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the Canon M and the RX0 have been discontinued, but can regularly be found used on ebay. The Canon M was replaced by the Canon EOS M3, while the RX0 was followed by the Sony RX0 II. Further information on the features and operation of the Canon M and RX0 can be found, respectively, in the Canon M Manual (free pdf) or the online Sony RX0 Manual.

Review summary

So how do things add up? Is the Canon M better than the Sony RX0 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS M:

• More detail: Offers more megapixels (17.9 vs 15.4MP) with a 8% higher linear resolution.
• Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in July 2012).

Reasons to prefer the Sony Cyber-shot DSC-RX0:

• More dynamic range: Captures a broader range of light and dark details (1.2 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Faster burst: Shoots at higher frequency (5.5 vs 4.3 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Has an integrated lens, whereas the Canon M necessitates an extra lens.
• More compact: Is smaller (59x41mm vs 109x66mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the Canon M).
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 5 years and 1 month of technical progress since the Canon M launch.

If the count of relative strengths (bullet points above) is taken as a measure, the RX0 is the clear winner of the contest (13 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 M and the Sony RX0 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Canon M or the RX0. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
