Panasonic GX80 versus Panasonic G85

The Panasonic Lumix DMC-GX80 (called Panasonic GX85 in some regions) and the Panasonic Lumix DMC-G85 (labelled Panasonic G80 in some countries) are two digital cameras that were announced, respectively, in April 2016 and September 2016. Both the GX80 and the G85 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 GX80 vs Panasonic G85

An illustration of the physical size and weight of the Panasonic GX80 and the Panasonic G85 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 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 – 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 Panasonic G85 is notably larger (32 percent) than the Panasonic GX80. Moreover, the G85 is markedly heavier (19 percent) than the GX80. It is noteworthy in this context that the G85 is splash and dust-proof, 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.

Concerning battery life, the GX80 gets 290 shots out of its DMW-BLG10 battery, while the G85 can take 330 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 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 GX80 was launched at a somewhat lower price (by 11 percent) than the G85, 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: Panasonic GX80 vs Panasonic G85

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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.

Panasonic GX80 and Panasonic G85 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 GX80 and the G85 have the same pixel density, as well as the same pixel size. It should, however, be noted that the G85 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.

GX80 versus G85 MP

For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 GX80 vs Panasonic G85

So what conclusions can be drawn? Is the Panasonic GX80 better than the Panasonic G85 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Panasonic Lumix DMC-GX80:

  • More detailed viewfinder: Has higher resolution electronic viewfinder (2765k vs 2360k dots).
  • More compact: Is smaller (122x71mm vs 128x89mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 79g or 16 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (11 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in April 2016).


Reasons to prefer the Panasonic Lumix DMC-G85:

  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (330 versus 290) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Was introduced somewhat (5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (5 points each). 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 before making a decision on a new camera.

GX80 05:05 G85

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX80 or the G85. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
