Panasonic GH5s versus Pentax KP

The Panasonic Lumix DC-GH5s and the Pentax KP are two enthusiast cameras that were officially introduced, respectively, in January 2018 and January 2017. The GH5s is a mirrorless interchangeable lens camera, while the KP is a DSLR. The cameras are based on a Four Thirds (GH5s) and an APS-C (KP) sensor. The Panasonic has a resolution of 9.9 megapixel, whereas the Pentax provides 24.1 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 Pentax KP

The physical size and weight of the Panasonic GH5s and the Pentax KP are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions 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 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 Pentax KP is somewhat smaller (2 percent) than the Panasonic GH5s. However, the KP is markedly heavier (7 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 KP can take 390 images on a single charge of its D-LI109 power pack.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The KP was launched at a markedly lower price (by 56 percent) than the GH5s, 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 GH5s vs Pentax KP

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Pentax KP an APS-C sensor. The sensor area in the KP is 63 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GH5s has a native 4:3 aspect ratio, while the one in the KP offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Panasonic GH5s and Pentax KP sensor measures

With 24.1MP, the KP offers a higher resolution than the GH5s (9.9MP), but the KP has smaller individual pixels (pixel pitch of 3.90μm versus 4.77μm for the GH5s). It is noteworthy in this context that the GH5s is a somewhat more recent model (by 11 months) than the KP, and its sensor might 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.

Unlike the GH5s, the KP has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

GH5s versus KP MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 video resolution than the KP. It can shoot video footage at 4K/60p, while the Pentax is limited to 1080/60i.

 

Feature comparison: Panasonic GH5s vs Pentax KP

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GH5s has an electronic viewfinder (3680k dots), while the KP 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 Pentax KP along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GH5s has a touchscreen, while the KP 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, 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 GH5s and the KP write their imaging data to SDXC cards. The GH5s features dual card slots, which can be very useful in case a memory card fails. In contrast, the KP only has one slot.

Both the GH5s and the KP are recent models that feature in their makers' current product line-up. Neither of the two has a direct predecessor, so perhaps they will constitute the origins of new camera lines for Panasonic and Pentax.

Review summary: Panasonic GH5s vs Pentax KP

So what is the bottom line? Which of the two cameras – the Panasonic GH5s or the Pentax KP – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

  • 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 GH5s is the clear winner of the match-up (16 : 7 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 16:07 KP

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 KP 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 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
