Panasonic GX800 versus Canon M6

The Panasonic Lumix DMC-GX800 (called Panasonic GX850 in some regions) and the Canon EOS M6 are two digital cameras that were revealed to the public, respectively, in January 2017 and February 2017. Both the GX800 and the M6 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX800) 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 GX800 and the Canon M6 are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the GX800 – 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 M6 is notably larger (10 percent) than the Panasonic GX800. Moreover, the M6 is substantially heavier (45 percent) than the GX800. In this context, it is worth noting that neither the GX800 nor the M6 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 GX800 was launched at a markedly lower price (by 30 percent) than the M6, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GX800 features a Four Thirds sensor and the Canon M6 an APS-C sensor. The sensor area in the M6 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 GX800 has a native 4:3 aspect ratio, while the one in the M6 offers a 3:2 aspect.

Sensor size

With 24MP, the M6 offers a higher resolution than the GX800 (15.8MP), but the M6 has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the GX800). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 have a sensor with sufficiently fast read-out times for moving pictures, but the GX800 provides a higher video resolution than the M6. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The GX800 and the M6 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 GX800 and Canon M6 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 GX800 and the M6 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX800 replaced the earlier Panasonic GF7, while the M6 followed on from the Canon M5.

Summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic GX800 and the Panasonic GX800? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Panasonic Lumix DMC-GX800:

  • 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).
  • Less heavy: Is lighter (by 121g or 31 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).

logo checkmark

Advantages of the Canon EOS M6:

  • 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.
  • Faster shutter: Has 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.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (4 points each). 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.

GX800 04:04 M6

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the GX800 or the M6 handle or 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known 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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
