Panasonic GX850 versus Canon M100

The Panasonic Lumix DMC-GX850 (called Panasonic GX800 in some regions) and the Canon EOS M100 are two digital cameras that were officially introduced, respectively, in January 2017 and August 2017. Both the GX850 and the M100 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX850) and an APS-C sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 24 MP.

Body comparison

The physical size and weight of the Panasonic GX850 and the Canon M100 are illustrated in the side-by-side display below. 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the GX850 – represents the basis or 100 percent across all the size and weight measures).

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 Panasonic GX850. Moreover, the M100 is markedly heavier (12 percent) than the GX850. In this context, it is worth noting that neither the GX850 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 the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M100 was somewhat cheaper (by 9 percent) than the GX850 at launch, but both cameras fall into the same price category. 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.

Sensor comparison

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. 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.

Of the two cameras under consideration, the Panasonic GX850 features a Four Thirds sensor and the Canon M100 an APS-C sensor. The sensor area in the M100 is 48 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the GX850 has a native 4:3 aspect ratio, while the one in the M100 offers a 3:2 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). Yet, 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 pixel-units. 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.

For most cameras, data on sensor performance has been reported by DXO Mark. 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 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX850 provides a higher video resolution than the M100. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The GX850 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 adjacent table lists some of the other core features of the Panasonic GX850 and Canon M100 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the GX850 and the M100 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX850 replaced the earlier Panasonic GF7, while the M100 followed on from the Canon M10.

Summary

So what is the bottom line? Is there a clear favorite between the Panasonic GX850 and the Panasonic GX850? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Advantages of 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 heavy: Is lighter (by 33g or 11 percent) and hence easier to carry around.
  • More heavily discounted: Has been on the market for longer (launched in January 2017).

Arguments in favor of the Canon EOS M100:

  • More detail: Has more megapixels (24 vs 15.8MP), which boosts linear resolution by 26%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Faster shutter: Has a higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Longer lasting: Gets more shots (295 versus 210) out of a single battery charge.
  • More modern: Was introduced somewhat (7 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the M100 comes out slightly ahead of the GX850 (6 : 5 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX850 or the M100. 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 hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
