Panasonic GH5s versus Panasonic GH5

The Panasonic Lumix DC-GH5s and the Panasonic Lumix DC-GH5 are two enthusiast cameras that were announced, respectively, in January 2018 and January 2017. Both the GH5s and the GH5 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GH5s has a resolution of 9.9 megapixel, whereas the GH5 provides 20.2 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 Panasonic GH5

The side-by-side display below illustrates the physical size and weight of the Panasonic GH5s and the Panasonic GH5. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button 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 100 percent across all the size and weight measures).

In this particular case, the Panasonic GH5s and the Panasonic GH5 have exactly the same width and height, and, thus, have identically-sized bodies. However, the GH5 is markedly heavier (10 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. 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.

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 GH5 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 Panasonic GH5

The size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

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 GH5s and Panasonic GH5 sensor measures

While the two cameras under review share the same sensor size, the GH5 offers a higher resolution of 20.2 megapixel, compared with 9.9 MP of the GH5s. This megapixel advantage translates into a 41 percent gain in linear resolution. On the other hand, these sensor specs imply that the GH5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.77μm for the GH5s). Moreover, it should be noted, that the GH5s is a somewhat more recent model (by 1 year) than the GH5, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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.

GH5s versus GH5 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. 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/60p).

 

Feature comparison: Panasonic GH5s vs Panasonic GH5

Apart from body and sensor, cameras can and do differ across a range of features. The GH5s and the GH5 are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 3680k dots. The following table reports on some other key feature differences and similarities of the Panasonic GH5s, the Panasonic GH5, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Review summary: Panasonic GH5s vs Panasonic GH5

So how do things add up? Which of the two cameras – the Panasonic GH5s or the Panasonic GH5 – has the upper hand? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Panasonic Lumix DC-GH5s:

  • More modern: Is somewhat more recent (announced 1 year after the GH5).


Reasons to prefer the Panasonic Lumix DC-GH5:

  • More detail: Has more megapixels (20.2 vs 9.9MP), which boosts linear resolution by 42%.
  • 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 on the market for longer (launched in January 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the GH5 emerges as the winner of the match-up (4 : 1 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 01:04 GH5

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the GH5s or the GH5 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
