Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M3 and the Sony Alpha A3000? 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 Sony A3000 are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

The M3 can be obtained in two different colors (black, white), while the A3000 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 A3000 is considerably larger (54 percent) than the Canon M3. Moreover, the A3000 is markedly heavier (12 percent) than the M3. In this context, it is worth noting that neither the M3 nor the A3000 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.

Concerning battery life, the M3 gets 250 shots out of its Canon LP-E17 battery, while the A3000 can take 470 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A3000 can be charged via the USB port, which can be very convenient when travelling.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The A3000 was launched at a markedly lower price (by 52 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

The size of the imaging sensor is a crucial determinant 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A3000 is 8 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (M3) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon M3 offers a higher resolution of 24 megapixels, compared with 19.8 MP of the Sony A3000. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.25μm for the A3000). However, it should be noted that the M3 is a somewhat more recent model (by 1 year and 5 months) than the A3000, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

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 Sony A3000 are 27.3 x 18.2 inches or 69.3 x 46.1 cm for good quality, 21.8 x 14.5 inches or 55.4 x 36.9 cm for very good quality, and 18.2 x 12.1 inches or 46.2 x 30.8 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 Sony Alpha A3000 are ISO 100 to ISO 16000 (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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 A3000 has a markedly higher DXO score than the M3 (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.9 bits higher color depth, 1 EV in additional dynamic range, and 0.1 stops of reduced 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A3000 provides a faster frame rate than the M3. It can shoot movie footage at 1080/60i, 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. For example, the A3000 has an electronic viewfinder (202k 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 table below summarizes some of the other core capabilities of the Canon M3 and Sony A3000 in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M3 has a touchscreen, while the A3000 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The M3 writes its imaging data to SDXC cards, while the A3000 uses SDXC or Memory Stick PRO Duo cards. The M3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the A3000 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 Sony Alpha A3000 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 A3000. 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 A3000 have been discontinued, but can regularly be found used on ebay. The M3 was replaced by the Canon M6, while the A3000 does not have a direct successor. Further information on the features and operation of the M3 and A3000 can be found, respectively, in the Canon M3 Manual (free pdf) or the online Sony A3000 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon M3 and the Sony A3000? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS M3:

• More detail: Offers more megapixels (24 vs 19.8MP) with a 10% higher linear resolution.
• 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 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (4.2 vs 2.5 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (111x68mm vs 128x91mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 45g or 11 percent) and hence easier to carry around.
• 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: Is somewhat more recent (announced 1 year and 5 months after the A3000).

Reasons to prefer the Sony Alpha A3000:

• Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Longer lasting: Gets more shots (470 versus 250) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• More affordable: Was introduced into a lower priced category (52 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in August 2013).

If the number of relative strengths (bullet points above) is taken as a guide, 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 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 Sony A3000 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 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 A3000. 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 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.

Care should be taken when interpreting the review scores above, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
