Panasonic GX80 versus Canon G7 X Mark II

The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Canon PowerShot G7 X Mark II are two digital cameras that were revealed to the public, respectively, in April 2016 and February 2016. The GX80 is a mirrorless interchangeable lens camera, while the G7X Mark II is a fixed lens compact. The cameras are based on a Four Thirds (GX80) and an one-inch (G7X Mark II) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Canon provides 20 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 GX80 vs Canon G7 X Mark II

An illustration of the physical size and weight of the Panasonic GX80 and the Canon G7 X Mark II is provided in the side-by-side display below. 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 use the toggle button 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 GX80 – 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 G7 X Mark II is notably smaller (25 percent) than the Panasonic GX80. In this context, it is worth noting that neither the GX80 nor the G7X Mark II 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 GX80 gets 290 shots out of its DMW-BLG10 battery, while the G7X Mark II can take 265 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. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison: Panasonic GX80 vs Canon G7 X Mark II

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 GX80 features a Four Thirds sensor and the Canon G7 X Mark II an one-inch sensor. The sensor area in the G7X Mark II is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the GX80 has a native 4:3 aspect ratio, while the one in the G7X Mark II offers a 3:2 aspect.

Despite having a smaller sensor, the G7X Mark II offers a higher resolution of 20 megapixel, compared with 15.8 MP of the 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.

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX80 provides a higher video resolution than the G7X Mark II. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison: Panasonic GX80 vs Canon G7 X Mark II

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX80 has an electronic viewfinder (2765k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X Mark II relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic GX80, the Canon G7 X Mark II, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the GX80 and the G7X Mark II are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The G7X Mark II replaced the earlier Canon G7 X, while the GX80 followed on from the Panasonic GX7.

Review summary: Panasonic GX80 vs Canon G7 X Mark II

So what is the bottom line? Is there a clear favorite between the Panasonic GX80 and the Canon G7 X Mark II? The listing below highlights the relative strengths of the two models.

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 low-light imaging: Features bigger pixels on a larger sensor for better high-ISO 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.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.

Reasons to prefer the Canon PowerShot G7 X Mark II:

• More detail: Has more megapixels (20 vs 15.8MP), which boosts linear resolution by 15%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Ready to shoot: Has an integrated lens, whereas the GX80 necessitates an extra lens.
• More compact: Is smaller (106x61mm vs 122x71mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens build in (unlike the GX80).
• More affordable: Was introduced at a lower price, despite coming with a build-in lens.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (6 points each). 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the GX80 or the G7X Mark II 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 where reviews by experts come in.

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