Panasonic GX80 versus Panasonic G7

The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Panasonic Lumix DMC-G7 are two digital cameras that were announced, respectively, in April 2016 and May 2015. Both the GX80 and the G7 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 GX80 and the Panasonic G7. Three consecutive perspectives from the front, the top, and the back are presented. 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 GX80 – 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 G7 is notably larger (24 percent) than the Panasonic GX80. However, the G7 is slightly lighter (4 percent) than the GX80. In this context, it is worth noting that neither the GX80 nor the G7 are weather-sealed.

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.

Concerning battery life, the GX80 gets 290 shots out of its DMW-BLG10 battery, while the G7 can take 350 images on a single charge of its DMW-BLC12 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7 was launched at a somewhat lower price (by 19 percent) than the GX80, 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and 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

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 GX80 and the G7 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GX80 is a somewhat more recent model (by 10 months) than the G7, and its sensor might have benefitted from technological advances during this time. 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.

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, 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 two cameras under consideration 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 G7 (2765k vs 2360k dots). The following table reports on some other key feature differences and similarities of the Panasonic GX80, the Panasonic G7, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The GX80 is a current model that online retailers, such as amazon, will have in stock. In contrast, the G7 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the G7 was succeeded by the Panasonic G85.

Summary

So how do things add up? Is the Panasonic GX80 better than the Panasonic G7 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer the Panasonic Lumix DMC-GX80:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 2360k dots).
  • Faster burst: Shoots at higher frequency (8 vs 7 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (122x71mm vs 125x86mm) and thus needs less room in the bag.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More modern: Is somewhat more recent (announced 10 months after the G7).

Arguments in favor of the Panasonic Lumix DMC-G7:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Gets more shots (350 versus 290) out of a single battery charge.
  • More affordable: Was released into a lower priced segment (19 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in May 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the GX80 comes out slightly ahead of the G7 (6 : 5 points). 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.

GX80 06:05 G7

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 GX80 or the G7 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 adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
