Panasonic G85 versus Canon G1 X Mark III

The Panasonic Lumix DMC-G85 (called Panasonic G80 in some regions) and the Canon PowerShot G1 X Mark III are two digital cameras that were announced, respectively, in September 2016 and October 2017. The G85 is a mirrorless interchangeable lens camera, while the G1X Mark III is a fixed lens compact. The cameras are based on a Four Thirds (G85) 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 G85 vs Canon G1 X Mark III

An illustration of the physical size and weight of the Panasonic G85 and the Canon G1 X Mark III is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size 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 G85 – 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 Canon G1 X Mark III is notably smaller (21 percent) than the Panasonic G85. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 G85 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 G85 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the G85 gets 330 shots out of its DMW-BLC12 battery, while the G1X Mark III can take 200 images on a single charge of its NB-13L 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. 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 G85 vs Canon G1 X Mark III

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 G85 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 G85 has a native 4:3 aspect ratio, while the one in the G1X Mark III offers a 3:2 aspect.

Panasonic G85 and Canon G1 X Mark III sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the G85 (15.8MP), but the G1X Mark III has marginally smaller individual pixels (pixel pitch of 3.72μm versus 3.77μm for the G85). Yet, the G1X Mark III is a somewhat more recent model (by 1 year) than the G85, 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 G85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G85 provides a higher video resolution than the G1X Mark III. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Panasonic G85 vs Canon G1 X Mark III

Beyond body and sensor, cameras can and do differ across a range of features. The G85 and the G1X Mark III are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The table below summarizes some of the other core capabilities of the Panasonic G85 and Canon G1 X Mark III in connection with corresponding information for a sample of similar cameras.

Review summary: Panasonic G85 vs Canon G1 X Mark III

So what conclusions can be drawn? Which of the two cameras – the Panasonic G85 or the Canon G1 X Mark III – has the upper hand? The listing below highlights the relative strengths of the two models.

ilogo

Reasons to prefer the Panasonic Lumix DMC-G85:

  • 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).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (330 versus 200) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in September 2016).

ilogo

Advantages of the Canon PowerShot G1 X Mark III:

  • 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.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Ready to shoot: Has an integrated lens, whereas the G85 necessitates an extra lens.
  • More compact: Is smaller (115x78mm vs 128x89mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the G85).
  • More modern: Was introduced somewhat (1 year) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III comes out slightly ahead of the G85 (7 : 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.

G85 06:07 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 says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G85 and the G1X Mark III in practical situations. 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).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, please note that some of the review sites have changed their methodology and reporting over time.
