Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M3 and the Panasonic Lumix DC-S1H? 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 Panasonic S1H. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The M3 can be obtained in two different colors (black, white), while the S1H 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 Panasonic S1H is considerably larger (128 percent) than the Canon M3. Moreover, the S1H is substantially heavier (187 percent) than the M3. It is noteworthy in this context that the S1H is splash and dust-proof, while the M3 does not feature any corresponding weather-sealing.

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 S1H can take 400 images on a single charge of its Panasonic DMW-BLJ31 power pack. The power pack in the S1H can be charged via the USB port, which can be very convenient when travelling.

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 83 percent) than the S1H, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon M3 features an APS-C sensor and the Panasonic S1H a full frame sensor. The sensor area in the S1H is 155 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Even though the S1H has a larger sensor, both cameras offer the same resolution of 24 megapixels. This implies that the S1H has a lower pixel density and larger individual pixels (with a pixel pitch of 5.94μm versus 3.72μm for the M3), which gives it a potential advantage in terms of light gathering capacity. In addition, the S1H is much more recent (by 4 years and 3 months) than the M3, and its sensor will have benefitted from technological advances during this time.

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

Unlike the M3, the S1H has the capacity to capture high quality composite images (96MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

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 Panasonic Lumix DC-S1H are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 S1H provides a better video resolution than the M3. It can shoot movie footage at 6K/30p, 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 S1H has an electronic viewfinder (5760k 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 adjacent table lists some of the other core features of the Canon M3 and Panasonic S1H along with similar information for a selection of comparators.

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

One difference between the cameras concerns the presence of an on-board flash. The M3 has one, while the S1H does not. While the built-in flash of the M3 is not very powerful, it can at times be useful as a fill-in light.

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 S1H is one of those camera that have an additional 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 Panasonic S1H 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 S1H write their files to SDXC cards. The S1H features dual card slots, which can be very useful in case a memory card fails. In contrast, the M3 only has one slot. The S1H supports UHS-II cards (on both slots), while the M3 can use UHS-I 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 Panasonic Lumix DC-S1H and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1H has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The M3 lacks such a headphone port.

Studio photographers will appreciate that the Panasonic S1H (unlike the M3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The S1H is a recent model that features in the current product line-up of Panasonic. In contrast, the M3 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the M3 was succeeded by the Canon M6. Further information on the features and operation of the M3 and S1H can be found, respectively, in the Canon M3 Manual (free pdf) or the online Panasonic S1H Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon M3 or the Panasonic S1H – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon EOS M3:

• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More compact: Is smaller (111x68mm vs 151x114mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 686g or 65 percent) and hence easier to carry around.

If the count of individual advantages (bullet points above) is taken as a guide, the S1H is the clear winner of the contest (27 : 7 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 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 Panasonic S1H 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 S1H. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.
