Panasonic GM5 versus Panasonic GX80

The Panasonic Lumix DMC-GM5 and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were revealed to the public, respectively, in September 2014 and April 2016. Both the GM5 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. 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 GM5 vs Panasonic GX80

The physical size and weight of the Panasonic GM5 and the Panasonic GX80 are illustrated 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 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 side – the GM5 – 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 GX80 is considerably larger (46 percent) than the Panasonic GM5. Moreover, the GX80 is substantially heavier (102 percent) than the GM5. In this context, it is worth noting that neither the GM5 nor the GX80 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 GM5 gets 220 shots out of its DMW-BLH7 battery, while the GX80 can take 290 images on a single charge of its DMW-BLG10 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 GM5 was somewhat cheaper (by 6 percent) than the GX80 at launch, but both cameras fall into the same price category. 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 GM5 vs Panasonic GX80

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. 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.

Panasonic GM5 and Panasonic GX80 sensor measures

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 GM5 and the GX80 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 1 year and 6 months) than the GM5, 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.

GM5 versus GX80 MP

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 GX80 has a markedly higher DXO score than the GM5 (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 0.9 EV in additional dynamic range, 0.1 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Review summary: Panasonic GM5 vs Panasonic GX80

So what conclusions can be drawn? Is the Panasonic GM5 better than the Panasonic GX80 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Panasonic Lumix DMC-GM5:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (99x60mm vs 122x71mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 215g or 50 percent) and hence easier to carry around.
  • More heavily discounted: Has been on the market for longer (launched in September 2014).


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 image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 1166k dots).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (8 vs 5.8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (290 versus 220) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the GX80 is the clear winner of the contest (13 : 4 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 when reflecting and deciding on a new camera.

GM5 04:13 GX80

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 GM5 or the GX80 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 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
