Canon M10 versus Panasonic GX800

The Canon EOS M10 and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were announced, respectively, in October 2015 and January 2017. Both the M10 and the GX800 are mirrorless interchangeable lens cameras that are based on an APS-C (M10) and a Four Thirds (GX800) sensor. The Canon has a resolution of 17.9 megapixel, whereas the Panasonic provides 15.8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon M10 vs Panasonic GX800

An illustration of the physical size and weight of the Canon M10 and the Panasonic GX800 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 M10 – represents 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 Panasonic GX800 is somewhat smaller (4 percent) than the Canon M10. Moreover, the GX800 is markedly lighter (11 percent) than the M10. In this context, it is worth noting that neither the M10 nor the GX800 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.

Concerning battery life, the M10 gets 255 shots out of its LP-E12 battery, while the GX800 can take 210 images on a single charge of its DMW-BLH7 power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M10 was somewhat cheaper (by 9 percent) than the GX800 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: Canon M10 vs Panasonic GX800

The size of the imaging sensor is a crucial determinant 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 M10 features an APS-C sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 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 GX800 offers a 4:3 aspect.

Sensor size

With 17.9MP, the M10 offers a higher resolution than the GX800 (15.8MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 4.31μm versus 3.77μm for the GX800) due to its larger sensor. However, the GX800 is a somewhat more recent model (by 1 year and 2 months) than the M10, 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 GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Sensor resolution

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"). Of the two cameras under consideration, the GX800 has a markedly higher DXO score than the M10 (overall score 8 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 1.9 EV in additional dynamic range, 0.4 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 better video resolution than the M10. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison: Canon M10 vs Panasonic GX800

Apart from body and sensor, cameras can and do differ across a range of features. The M10 and the GX800 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 following table reports on some other key feature differences and similarities of the Canon M10, the Panasonic GX800, and comparable cameras.

The GX800 is a current model that online retailers, such as amazon, will have in stock. In contrast, the M10 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the M10 was succeeded by the Canon M100.

Review summary: Canon M10 vs Panasonic GX800

So how do things add up? Which of the two cameras – the Canon M10 or the Panasonic GX800 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


logo checkmark

Arguments in favor of the Canon EOS M10:

  • More detail: Offers more megapixels (17.9 vs 15.8MP) with a 8% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Longer lasting: Can take more shots (255 versus 210) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in October 2015).

logo checkmark

Reasons to prefer the Panasonic Lumix DMC-GX800:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Faster burst: Shoots at higher frequency (10 vs 4.6 flaps/sec) to capture the decisive moment.
  • Less heavy: Has a lower weight (by 32g or 11 percent) and is thus easier to take along.
  • More modern: Was introduced somewhat (1 year and 2 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GX800 comes out slightly ahead of the M10 (7 : 6 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.

M10 06:07 GX800

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the M10 or the GX800 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
