Panasonic G80 versus Panasonic GX8

The Panasonic Lumix DMC-G80 (called Panasonic G85 in some regions) and the Panasonic Lumix DMC-GX8 are two digital cameras that were revealed to the public, respectively, in September 2016 and July 2015. Both the G80 and the GX8 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G80 has a resolution of 15.8 megapixel, whereas the GX8 provides 20.2 MP.

Body comparison

An illustration of the physical size and weight of the Panasonic G80 and the Panasonic GX8 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 G80 – 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 GX8 is somewhat smaller (9 percent) than the Panasonic G80. Moreover, the GX8 is slightly lighter (4 percent) than the G80. 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 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 G80 was launched at a somewhat lower price (by 25 percent) than the GX8, 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 sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras 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

While the two cameras under review share the same sensor size, the GX8 offers a higher resolution of 20.2 megapixel, compared with 15.8 MP of the G80. This megapixel advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX8 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.77μm for the G80). Moreover, it should be noted, that the G80 is a somewhat more recent model (by 1 year and 2 months) than the GX8, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. Coming back to sensor resolution, it should be mentioned that the G80 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the GX8 has a markedly higher DXO score than the G80 (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.1 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The G80 and the GX8 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 adjacent table lists some of the other core features of the Panasonic G80 and Panasonic GX8 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the G80 and the GX8 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX8 replaced the earlier Panasonic GX7, while the G80 followed on from the Panasonic G7.

Summary

So what conclusions can be drawn? Is the Panasonic G80 better than the Panasonic GX8 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Panasonic Lumix DMC-G80:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 2 months after the GX8).

Advantages of the Panasonic Lumix DMC-GX8:

  • More detail: Has more megapixels (20.2 vs 15.8MP), which boosts linear resolution by 13%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
  • Faster shutter: Has a higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • More heavily discounted: Has been on the market for longer (launched in July 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the GX8 comes out slightly ahead of the G80 (5 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.

G80 04:05 GX8

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G80 and the GX8 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 hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
