Panasonic GX9 versus Canon M5

The Panasonic Lumix DC-GX9 and the Canon EOS M5 are two digital cameras that were revealed to the public, respectively, in February 2018 and September 2016. Both the GX9 and the M5 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX9) and an APS-C (M5) sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Canon provides 24 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: Panasonic GX9 vs Canon M5

An illustration of the physical size and weight of the Panasonic GX9 and the Canon M5 is provided in the side-by-side display below. 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 dimensions 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 GX9 – 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 M5 is notably larger (16 percent) than the Panasonic GX9. Moreover, the M5 is markedly heavier (5 percent) than the GX9. In this context, it is worth noting that neither the GX9 nor the M5 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 GX9 gets 260 shots out of its DMW-BLG10 battery, while the M5 can take 295 images on a single charge of its LP-E17 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The GX9 was launched at a somewhat lower price (by 13 percent) than the M5, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Panasonic GX9 vs Canon M5

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GX9 features a Four Thirds sensor and the Canon M5 an APS-C sensor. The sensor area in the M5 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 GX9 has a native 4:3 aspect ratio, while the one in the M5 offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Panasonic GX9 and Canon M5 sensor measures

With 24MP, the M5 offers a higher resolution than the GX9 (20.2MP), but the M5 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 3.34μm for the GX9) due to its larger sensor. However, the GX9 is a somewhat more recent model (by 1 year and 4 months) than the M5, 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 GX9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

GX9 versus M5 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX9 features an electronic shutter, which makes silent shooting and higher burst speeds possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the GX9 and the M5 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX9 replaced the earlier Panasonic GX8, while the M5 does not have a direct predecessor.

Review summary: Panasonic GX9 vs Canon M5

So how do things add up? Is the Panasonic GX9 better than the Canon M5 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Panasonic Lumix DC-GX9:

  • 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).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 2360k dots).
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (124x72mm vs 116x89mm) and thus needs less room in the bag.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 4 months after the M5).

ilogo

Arguments in favor of the Canon EOS M5:

  • More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1240k dots).
  • Longer lasting: Gets more shots (295 versus 260) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in September 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the GX9 comes out slightly ahead of the M5 (8 : 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.

GX9 08:07 M5

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 GX9 or the M5 handle or perform in practice. 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
