Panasonic GH5s versus Sony A850

The Panasonic Lumix DC-GH5s and the Sony Alpha A850 are two digital cameras that were announced, respectively, in January 2018 and August 2009. The GH5s is a mirrorless interchangeable lens camera, while the A850 is a DSLR. The cameras are based on a Four Thirds (GH5s) and a full frame (A850) sensor. The Panasonic has a resolution of 9.9 megapixel, whereas the Sony provides 24.4 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 A850

The side-by-side display below illustrates the physical size and weight of the Panasonic GH5s and the Sony A850. 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 GH5s – 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 Sony A850 is notably larger (34 percent) than the Panasonic GH5s. Moreover, the A850 is substantially heavier (36 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the GH5s gets 440 shots out of its DMW-BLF19 battery, while the A850 can take 880 images on a single charge of its NP-FM500H 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 A850 was launched at a somewhat lower price (by 20 percent) than the GH5s, 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 A850

The size of the sensor inside a digital camera is one of the key determinants 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.

Of the two cameras under consideration, the Panasonic GH5s features a Four Thirds sensor and the Sony A850 a full frame sensor. The sensor area in the A850 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 A850 offers a 3:2 aspect.

Sensor size

With 24.4MP, the A850 offers a higher resolution than the GH5s (9.9MP), but the A850 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.77μm for the GH5s) due to its larger sensor. However, the GH5s is a much more recent model (by 8 years and 4 months) than the A850, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the GH5s has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GH5s indeed provides movie recording capabilities, while the A850 does not. The highest resolution format that the GH5s can use is 4K/60p.

Feature comparison: Panasonic GH5s vs Sony A850

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH5s has an electronic viewfinder (3680k dots), while the A850 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Panasonic GH5s and Sony A850 along with similar information for a selection of comparators.

The GH5s is a current model that online retailers, such as amazon, will have in stock. In contrast, the A850 has been discontinued (but it can be found pre-owned on eBay). There has not been a direct replacement model for the A850 from Sony.

Review summary: Panasonic GH5s vs Sony A850

So what is the bottom line? Which of the two cameras – the Panasonic GH5s or the Sony A850 – has the upper hand? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Panasonic Lumix DC-GH5s:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Broader imaging potential: Can record not only still images but also 4K/60p movies.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 922k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (12 vs 3 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (139x98mm vs 156x117mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 235g or 26 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More modern: Reflects 8 years and 4 months of technical progress since the A850 launch.

Advantages of the Sony Alpha A850:

  • More detail: Has more megapixels (24.4 vs 9.9MP), which boosts linear resolution by 59%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (880 versus 440) out of a single battery charge.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was released into a lower priced segment (20 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in August 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the GH5s is the clear winner of the match-up (12 : 8 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.

GH5s 12:08 A850

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GH5s and the A850 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
