Panasonic GH5s versus Sony A7R II

The Panasonic Lumix DC-GH5s and the Sony Alpha A7R II are two enthusiast cameras that were revealed to the public, respectively, in January 2018 and June 2015. Both the GH5s and the A7R II are mirrorless interchangeable lens cameras that are based on a Four Thirds (GH5s) and a full frame (A7R II) sensor. The Panasonic has a resolution of 9.9 megapixel, whereas the Sony provides 42.2 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: Panasonic GH5s vs Sony A7R II

The side-by-side display below illustrates the physical size and weight of the Panasonic GH5s and the Sony A7R II. Three successive views from the front, the top, and the rear 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 – the GH5s – 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 Sony A7R II is notably smaller (10 percent) than the Panasonic GH5s. Moreover, the A7R II is markedly lighter (5 percent) than the GH5s. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 Micro Four Thirds Lens Catalog (GH5s) and the Sony FE Lens Catalog (A7R II). 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 GH5s gets 440 shots out of its DMW-BLF19 battery, while the A7R II can take 290 images on a single charge of its NP-FW50 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 GH5s was launched at a somewhat lower price (by 22 percent) than the A7R II, 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 GH5s vs Sony A7R II

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GH5s features a Four Thirds sensor and the Sony A7R II a full frame sensor. The sensor area in the A7R II is 283 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the GH5s has a native 4:3 aspect ratio, while the one in the A7R II offers a 3:2 aspect.

Panasonic GH5s and Sony A7R II sensor measures

With 42.2MP, the A7R II offers a higher resolution than the GH5s (9.9MP), but the A7R II has smaller individual pixels (pixel pitch of 4.52μm versus 4.77μm for the GH5s). Yet, the GH5s is a much more recent model (by 2 years and 7 months) than the A7R II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GH5s provides a higher frame rate than the A7R II. It can shoot video footage at 4K/60p, while the Sony is limited to 4K/30p.

Feature comparison: Panasonic GH5s vs Sony A7R II

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GH5s offers a substantially higher resolution than the one in the A7R II (3680k vs 2400k dots).

If the number of relative strengths (bullet points above) is taken as a guide, the GH5s is the clear winner of the match-up (10 : 4 points). 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.

GH5s 10:04 A7R II

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GH5s and the A7R II in practical situations. 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).

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
