Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A5100 and the Canon EOS M100? 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 Sony A5100 and the Canon M100. 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.

Both cameras are available in two different colors (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M100 is somewhat larger (4 percent) than the Sony A5100. Moreover, the M100 is markedly heavier (7 percent) than the A5100. In this context, it is worth noting that neither the A5100 nor the M100 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 A5100 gets 400 shots out of its Sony NP-FW50 battery, while the M100 can take 295 images on a single charge of its Canon LP-E12 power pack. The power pack in the A5100 can be charged via the USB port, so that it is not always necessary to take the battery charger along 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. The M100 was somewhat cheaper (by 9 percent) than the A5100 at launch, but both cameras fall into the same price category. 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the M100 is 10 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (A5100) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the A5100 has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the A5100 has a lower pixel density and larger individual pixels (with a pixel pitch of 3.91μm versus 3.72μm for the M100), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the M100 is much more recent (by 3 years) than the A5100, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Sony Alpha A5100 has a native sensitivity range from ISO 100 to ISO 25600. The Canon EOS M100 offers exactly the same ISO settings.

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, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The A5100 and the M100 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 Sony A5100, the Canon M100, and comparable cameras.

Both the A5100 and the M100 have been discontinued, but can regularly be found used on ebay. The M100 was replaced by the Canon M200, while the A5100 does not have a direct successor. Further information on the features and operation of the A5100 and M100 can be found, respectively, in the Sony A5100 Manual (free pdf) or the online Canon M100 Manual.

Review summary

So how do things add up? Is the Sony A5100 better than the Canon M100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Sony Alpha A5100:

• Longer lasting: Can take more shots (400 versus 295) on a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• More heavily discounted: Has been available for much longer (launched in August 2014).

Reasons to prefer the Canon EOS M100:

• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 3 years of technical progress since the A5100 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (3 points each). 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 Sony A5100 and the Canon M100 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A5100 or the M100. 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.
