Panasonic G80 versus Panasonic GX80

The Panasonic Lumix DMC-G80 (called Panasonic G85 in some regions) and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were announced, respectively, in September 2016 and April 2016. Both the G80 and the GX80 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 15.8 megapixel.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic G80 and the Panasonic GX80. Three successive views from the front, the top, and the rear are shown. All size 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 G80 – 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 Panasonic GX80 is notably smaller (24 percent) than the Panasonic G80. Moreover, the GX80 is markedly lighter (16 percent) than the G80. It is worth mentioning in this context that the G80 is splash and dust resistant, while the GX80 does not feature any corresponding weather-sealing.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX80 was launched at a somewhat lower price (by 11 percent) than the G80, 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

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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.8 megapixel. This similarity in sensor specs implies that both the G80 and the GX80 have the same pixel density, as well as the same pixel size. It should, however, be noted that the G80 is a somewhat more recent model (by 5 months) than the GX80, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the GX80 offers a higher resolution than the one in the G80 (2765k vs 2360k dots). The table below summarizes some of the other core capabilities of the Panasonic G80 and Panasonic GX80 in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Summary

So how do things add up? Is there a clear favorite between the Panasonic G80 and the Panasonic G80? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Panasonic Lumix DMC-G80:

  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Can take more shots (330 versus 290) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Is somewhat more recent (announced 5 months after the GX80).

Advantages of the Panasonic Lumix DMC-GX80:

  • More detailed viewfinder: Has a higher resolution electronic viewfinder (2765k vs 2360k dots).
  • More compact: Is smaller (122x71mm vs 128x89mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 79g or 16 percent) and is thus easier to take along.
  • More affordable: Was released into a lower priced segment (11 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in April 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the GX80 comes out slightly ahead of the G80 (5 : 4 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.

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 G80 and the GX80 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
