Panasonic GX850 versus Panasonic GX85

The Panasonic Lumix DMC-GX850 (called Panasonic GX800 in some regions) and the Panasonic Lumix DMC-GX85 (labelled Panasonic GX80 in some countries) are two digital cameras that were announced, respectively, in January 2017 and April 2016. Both the GX850 and the GX85 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 GX850 vs Panasonic GX85

The physical size and weight of the Panasonic GX850 and the Panasonic GX85 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions 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 GX850 – 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 GX85 is notably larger (25 percent) than the Panasonic GX850. Moreover, the GX85 is substantially heavier (58 percent) than the GX850. In this context, it is worth noting that neither the GX850 nor the GX85 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 GX850 gets 210 shots out of its DMW-BLH7 battery, while the GX85 can take 290 images on a single charge of its DMW-BLG10 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The GX850 was launched at a markedly lower price (by 31 percent) than the GX85, which puts it into a different market segment. 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 GX850 vs Panasonic GX85

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 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 GX850 and Panasonic GX85 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 GX850 and the GX85 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GX850 is a somewhat more recent model (by 9 months) than the GX85, 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.

GX850 versus GX85 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). 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 are not only capable of taking still images, but can also record movies. 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: Panasonic GX850 vs Panasonic GX85

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX85 has an electronic viewfinder (2765k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX850 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GX850 and Panasonic GX85 along with similar information for a selection of comparators.

One feature that differentiates the GX85 and the GX850 is in-body image stabilization (IBIS). The GX85 reduces the risk of handshake-induced blur with all attached lenses, while the GX850 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the GX850 and the GX85 write their imaging data to SDXC cards.

Review summary: Panasonic GX850 vs Panasonic GX85

So what conclusions can be drawn? Is the Panasonic GX850 better than the Panasonic GX85 or vice versa? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Panasonic Lumix DMC-GX850:

  • More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
  • Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (107x65mm vs 122x71mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 157g or 37 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 9 months after the GX85).


Advantages of the Panasonic Lumix DMC-GX85:

  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Longer lasting: Gets more shots (290 versus 210) out of a single battery charge.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in April 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the GX85 comes out slightly ahead of the GX850 (7 : 6 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 before making a camera decision.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX850 or the GX85. 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 table below summarizes the assessments of some of the best known 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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
