Panasonic GX85 versus Canon G1 X Mark III

The Panasonic Lumix DMC-GX85 (called Panasonic GX80 in some regions) and the Canon PowerShot G1 X Mark III are two digital cameras that were revealed to the public, respectively, in April 2016 and October 2017. The GX85 is a mirrorless interchangeable lens camera, while the G1X Mark III is a fixed lens compact. The cameras are based on a Four Thirds (GX85) and an APS-C (G1X Mark III) sensor. The Panasonic has a resolution of 15.8 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 GX85 vs Canon G1 X Mark III

The physical size and weight of the Panasonic GX85 and the Canon G1 X Mark III are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth 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 GX85 – 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 G1 X Mark III is somewhat larger (4 percent) than the Panasonic GX85. It is noteworthy in this context that the G1X Mark III is splash and dust-proof, while the GX85 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark III has a lens build in, whereas the GX85 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 GX85 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GX85 gets 290 shots out of its DMW-BLG10 battery, while the G1X Mark III can take 200 images on a single charge of its NB-13L power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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. 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: Panasonic GX85 vs Canon G1 X Mark III

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 GX85 features a Four Thirds sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 48 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GX85 has a native 4:3 aspect ratio, while the one in the G1X Mark III offers a 3:2 aspect.

Panasonic GX85 and Canon G1 X Mark III sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the GX85 (15.8MP), but the G1X Mark III has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the GX85). Yet, the G1X Mark III is a somewhat more recent model (by 1 year and 6 months) than the GX85, 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 GX85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The G1X Mark III has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX85 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 GX85 and the G1X Mark III write their imaging data to SDXC cards.

  • 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.
  • Richer colors: Larger sensor generates 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 autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the GX85 necessitates an extra lens.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the GX85).
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the G1X Mark III is the clear winner of the contest (14 : 8 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.

GX85 08:14 G1X Mark III

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 GX85 or the G1X Mark III handle or perform in practice. 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
