Canon G7 X Mark II versus Panasonic GX80

The Canon PowerShot G7 X Mark II and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were announced, respectively, in February 2016 and April 2016. The G7X Mark II is a fixed lens compact, while the GX80 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (G7X Mark II) and a Four Thirds (GX80) sensor. The Canon has a resolution of 20 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 G7 X Mark II vs Panasonic GX80

The physical size and weight of the Canon G7 X Mark II and the Panasonic GX80 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. 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 side – the G7X Mark II – represents the basis for the calculations 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 GX80 is notably larger (34 percent) than the Canon G7 X Mark II. In this context, it is worth noting that neither the G7X Mark II nor the GX80 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens build in, whereas the GX80 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the GX80 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G7X Mark II gets 265 shots out of its NB-13L battery, while the GX80 can take 290 images on a single charge of its DMW-BLG10 power pack.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X Mark II was launched at a lower price than the GX80, despite having a lens build in. 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.

 

Sensor comparison: Canon G7 X Mark II vs Panasonic GX80

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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G7 X Mark II features an one-inch sensor and the Panasonic GX80 a Four Thirds sensor. The sensor area in the GX80 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the G7X Mark II has a native 3:2 aspect ratio, while the one in the GX80 offers a 4:3 aspect.

Canon G7 X Mark II and Panasonic GX80 sensor measures

Despite having a smaller sensor, the Canon G7 X Mark II offers a higher resolution of 20 megapixel, compared with 15.8 MP of the Panasonic GX80. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 3.77μm for the GX80). 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 GX80 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

G7X Mark II versus GX80 MP

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 reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX80 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the G7X Mark II and the GX80 write their imaging data to SDXC cards.

  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the GX80).
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GX80:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: Larger pixels generate images with better, more accurate colors.
  • More dynamic range: Capable of capturing a wider spectrum of light and dark details.
  • Better low-light sensitivity: Can be used in poorly lit environments and still produce good images.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.

If the count of individual advantages (bullet points above) is taken as a guide, the GX80 is the clear winner of the contest (11 : 6 points). 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 before making a decision on a new camera.

G7X Mark II 06:11 GX80

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G7X Mark II and the GX80 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Thus, a score needs to be put into the context of the launch date and the launch price 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, please note that some of the review sites have changed their methodology and reporting over time.
