Canon M10 vs Panasonic G3
The Canon EOS M10 and the Panasonic Lumix DMC-G3 are two digital cameras that were officially introduced, respectively, in October 2015 and May 2011. Both the M10 and the G3 are mirrorless interchangeable lens cameras that are based on an APS-C (M10) and a Four Thirds (G3) sensor. The Canon has a resolution of 17.9 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 M10 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 side-by-side display below illustrates the physical size and weight of the Canon M10 and the Panasonic G3. 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 M10 can be obtained in two different colors (black, white), while the G3 is available in four color-versions (black, brown, red, white).
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 larger (33 percent) than the Canon M10. Moreover, the G3 is markedly heavier (12 percent) than the M10. In this context, it is worth noting that neither the M10 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 M10 was launched at a somewhat lower price (by 17 percent) than the G3, which makes it more attractive for photographers on a tight budget. 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.
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. 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 M10 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 M10 has a native 3:2 aspect ratio, while the one in the G3 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 17.9MP, the M10 offers a higher resolution than the G3 (15.8MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.77μm for the G3) due to its larger sensor. Moreover, the M10 is a much more recent model (by 4 years and 5 months) than the G3, 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 M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10 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 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 M10 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M10 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 DMC-G3 are ISO 160 to ISO 6400 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 M10 has a notably higher overall DXO score than the G3 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.2 bits higher color depth, 0.8 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G3 provides a faster frame rate than the M10. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G3 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the M10 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon M10 and Panasonic G3 in connection with corresponding information for a sample of similar cameras.

Concerning the storage of imaging data, both the M10 and the G3 write their files to SDXC cards. The M10 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 M10 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 M10 offers wifi support, while the G3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the M10 and the G3 have been discontinued, but can regularly be found used on eBay. The G3 was replaced by the Panasonic G5, while the M10 was followed by the Canon M100. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So what conclusions can be drawn? Is the Canon M10 better than the Panasonic G3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS M10:
- More detail: Offers more megapixels (17.9 vs 15.8MP) with a 8% higher linear resolution.
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.2 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (0.8 EV of extra DR).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- Faster burst: Shoots at higher frequency (4.6 vs 4 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (108x67mm vs 115x84mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 35g or 10 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 affordable: Was introduced into a lower priced segment (17 percent cheaper at launch).
- More modern: Reflects 4 years and 5 months of technical progress since the G3 launch.
Advantages of the Panasonic Lumix DMC-G3:
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in May 2011).
If the count of individual advantages (bullet points above) is taken as a guide, the M10 is the clear winner of the match-up (14 : 5 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the M10 and the G3 in practical situations. 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
