Canon M5 vs Panasonic G3
The Canon EOS M5 and the Panasonic Lumix DMC-G3 are two digital cameras that were announced, respectively, in September 2016 and May 2011. Both the M5 and the G3 are mirrorless interchangeable lens cameras that are based on an APS-C (M5) and a Four Thirds (G3) sensor. The Canon has a resolution of 24 megapixels, whereas the Panasonic provides 15.8 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M5 and the Panasonic Lumix DMC-G3? 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.
The physical size and weight of the Canon M5 and the Panasonic G3 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 width, height and depth dimensions are rounded to the nearest millimeter.
The G3 can be obtained in four different colors (black, brown, red, white), while the M5 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 G3 is notably smaller (6 percent) than the Canon M5. Moreover, the G3 is markedly lighter (21 percent) than the M5. In this context, it is worth noting that neither the M5 nor the G3 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 G3 was launched at a markedly lower price (by 39 percent) than the M5, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 M5 features an APS-C sensor and the Panasonic G3 a Four Thirds sensor. The sensor area in the G3 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the M5 has a native 3:2 aspect ratio, while the one in the G3 offers a 4:3 aspect.
With 24MP, the M5 offers a higher resolution than the G3 (15.8MP), but the M5 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the G3). However, the M5 is a much more recent model (by 5 years and 4 months) than the G3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon M5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M5 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 Panasonic G3 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The M5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M5 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Panasonic Lumix DMC-G3 are ISO 160 to ISO 6400 (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 M5 provides substantially higher image quality than the G3, with an overall score that is 21 points higher. This advantage is based on 2.4 bits higher color depth, 1.8 EV in additional dynamic range, and 0.9 stops in additional low light sensitivity. 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the M5 provides a higher frame rate than the G3. It can shoot video footage at 1080/60p, while the Panasonic is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the M5 offers a substantially higher resolution than the one in the G3 (2360k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Canon M5, the Panasonic G3, and comparable cameras.

Concerning the storage of imaging data, both the M5 and the G3 write their files to SDXC cards. The M5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G3 cannot take advantage of Ultra High Speed SD cards.
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 M5 and Panasonic Lumix DMC-G3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M5 has a microphone port, which is missing on the G3. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the M5 and the G3 have been discontinued, but can regularly be found used on ebay. The G3 was replaced by the Panasonic G5, while the M5 does not have a direct successor. Further information on the features and operation of the M5 and G3 can be found, respectively, in the Canon M5 Manual (free pdf) or the online Panasonic G3 Manual.
So what conclusions can be drawn? Is there a clear favorite between the Canon M5 and the Panasonic G3? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

- More modern: Reflects 5 years and 4 months of technical progress since the G3 launch.
Arguments in favor of the Panasonic Lumix DMC-G3:
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Less heavy: Has a lower weight (by 91g or 21 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in May 2011).
If the count of relative strengths (bullet points above) is taken as a measure, the M5 is the clear winner of the match-up (17 : 4 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 M5 and the Panasonic G3 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 incomplete and does no justice, for example, to the way the M5 or the G3 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
