Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M100 and the Panasonic Lumix DMC-GX850? 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 M100 and the Panasonic GX850. 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 measures are rounded to the nearest millimeter.
The M100 can be obtained in two different colors (black, white), while the GX850 is available in three color-versions (black, silver, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX850 is somewhat smaller (4 percent) than the Canon M100. Moreover, the GX850 is markedly lighter (11 percent) than the M100. In this context, it is worth noting that neither the M100 nor the GX850 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. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

Any camera decision will obviously take relative prices into account. 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 GX850 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. 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon M100 features an APS-C sensor and the Panasonic GX850 a Four Thirds sensor. The sensor area in the GX850 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 M100 has a native 3:2 aspect ratio, while the one in the GX850 offers a 4:3 aspect.
With 24MP, the M100 offers a higher resolution than the GX850 (15.8MP), but the M100 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the GX850). However, the M100 is a somewhat more recent model (by 7 months) than the GX850, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GX850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon M100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M100 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Panasonic GX850 are 23 x 17.2 inch or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inch or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inch or 38.9 x 29.2 cm for excellent quality prints.
The M100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M100 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Panasonic Lumix DMC-GX850 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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 review, the M100 has a notably higher overall DXO score than the GX850 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 0.4 EV of lower dynamic range, and 1.1 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 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 GX850 provides a better video resolution than the M100. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The M100 and the GX850 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 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 GX850 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 GX850 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 M100 and the GX850 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 M100 and Panasonic Lumix DMC-GX850 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The GX850 is a recent model that features in the current product line-up of Panasonic. In contrast, the M100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the M100 was succeeded by the Canon M200. 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 there a clear favorite between the Canon M100 and the Panasonic GX850? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS M100:
- More detail: Offers more megapixels (24 vs 15.8MP) with a 26% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (1.1 stops ISO advantage).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Can take more shots (295 versus 210) on a single battery charge.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Is somewhat more recent (announced 7 months after the GX850).
Reasons to prefer the Panasonic Lumix DMC-GX850:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Faster burst: Shoots at higher frequency (10 vs 6.1 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Less heavy: Has a lower weight (by 33g or 11 percent) and is thus easier to take along.
- More heavily discounted: Has been on the market for longer (launched in January 2017).
If the count of relative strengths (bullet points above) is taken as a measure, the M100 emerges as the winner of the contest (10 : 7 points). 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 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 M100 and the Panasonic GX850 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 says little about, for example, the shooting experience and imaging performance of the M100 and the GX850 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.
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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
