Sony A6000 versus Panasonic GX85

The Sony Alpha A6000 and the Panasonic Lumix DMC-GX85 (labelled Panasonic GX80 in some countries) are two digital cameras that were announced, respectively, in February 2014 and April 2016. Both the A6000 and the GX85 are mirrorless interchangeable lens cameras that are based on an APS-C (A6000) and a Four Thirds (GX85) sensor. The Sony has a resolution of 24 megapixel, whereas the Panasonic provides 15.8 MP. 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: Sony A6000 vs Panasonic GX85

The physical size and weight of the Sony A6000 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 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 A6000 – 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 (8 percent) than the Sony A6000. Moreover, the GX85 is markedly heavier (24 percent) than the A6000. In this context, it is worth noting that neither the A6000 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Sony E-Mount Lens Catalog (A6000) and the Micro Four Thirds Lens Catalog (GX85). 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 A6000 gets 360 shots out of its NP-FW50 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. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera purchase will naturally be influenced heavily by the price. 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 A6000 was launched at a somewhat lower price (by 25 percent) than the GX85, 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: Sony A6000 vs Panasonic GX85

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.

Of the two cameras under consideration, the Sony A6000 features an APS-C sensor and the Panasonic GX85 a Four Thirds sensor. The sensor area in the GX85 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the A6000 has a native 3:2 aspect ratio, while the one in the GX85 offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Sony A6000 and Panasonic GX85 sensor measures

With 24MP, the A6000 offers a higher resolution than the GX85 (15.8MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.77μm for the GX85) due to its larger sensor. However, the GX85 is a somewhat more recent model (by 2 years and 1 month) than the A6000, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GX85 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The A6000 has on-sensor phase detect pixels, which results in relatively fast and reliable autofocus acquisition during video recording.

A6000 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"). Of the two cameras under review, the A6000 provides substantially higher image quality than the GX85, with an overall score that is 11 points higher. This advantage is based on 1.2 bits higher color depth, 0.5 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX85 has a touchscreen, while the A6000 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX85 features 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).

The A6000 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the GX85 uses SDXC cards.

A6000 11:08 GX85

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 A6000 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
