Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX8 and the Pentax K-5? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic GX8 and the Pentax K-5. 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.

The GX8 can be obtained in two different colors (black, silver), while the K-5 is only available in black.

Size Panasonic GX8 vs Pentax K-5
Compare GX8 versus K-5 top
Comparison GX8 or K-5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-5 is notably larger (22 percent) than the Panasonic GX8. Moreover, the K-5 is substantially heavier (56 percent) than the GX8. 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 and compare 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 GX8 gets 330 shots out of its DMW-BLC12 battery, while the K-5 can take 740 images on a single charge of its D-LI90 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 K-5 was somewhat cheaper (by 8 percent) than the GX8 at launch, but both cameras fall into the same price category. 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

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic GX8 features a Four Thirds sensor and the Pentax K-5 an APS-C sensor. The sensor area in the K-5 is 65 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 GX8 has a native 4:3 aspect ratio, while the one in the K-5 offers a 3:2 aspect.

Panasonic GX8 and Pentax K-5 sensor measures

Despite having a smaller sensor, the Panasonic GX8 offers a higher resolution of 20.2 megapixels, compared with 16.1 MP of the Pentax K-5. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.81μm for the K-5). However, it should be noted that the GX8 is much more recent (by 4 years and 9 months) than the K-5, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Panasonic GX8 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX8 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Pentax K-5 are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.

The Panasonic Lumix DMC-GX8 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Pentax K-5 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 80-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

GX8 versus K-5 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. Of the two cameras under consideration, the K-5 has a markedly higher DXO score than the GX8 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.2 bits higher color depth, 1.5 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GX8 provides a higher video resolution than the K-5. It can shoot video footage at 4K/30p, while the Pentax is limited to 1080/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX8 has an electronic viewfinder (2360k dots), while the K-5 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the GX8 has a higher magnification than the one of the K-5 (0.77x vs 0.61x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Panasonic GX8 and Pentax K-5 along with similar information for a selection of comparators.

Notes: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX8 has a touchscreen, while the K-5 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The GX8 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the K-5 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GX8 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GX8 and the Pentax K-5 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

Concerning the storage of imaging data, both the GX8 and the K-5 write their files to SDXC cards. The GX8 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the K-5 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Panasonic Lumix DMC-GX8 and Pentax K-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX8 offers wifi support, while the K-5 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Pentax K-5 (unlike the GX8) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GX8 and the K-5 have been discontinued, but can regularly be found used on ebay. The K-5 was replaced by the Pentax K-5 II, while the GX8 was followed by the Panasonic GX9. Further information on the features and operation of the GX8 and K-5 can be found, respectively, in the Panasonic GX8 Manual (free pdf) or the online Pentax K-5 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic GX8 and the Pentax K-5? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Panasonic Lumix DMC-GX8:

  • More detail: Offers more megapixels (20.2 vs 16.1MP) with a 10% higher linear resolution.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/25p).
  • More framing info: Has an electronic viewfinder that displays shooting data.

ilogo

Arguments in favor of the Pentax K-5:

  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Longer lasting: Gets more shots (740 versus 330) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More heavily discounted: Has been around for much longer (launched in September 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the GX8 is the clear winner of the match-up (17 : 9 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GX8 17:09 K-5

How about other alternatives? Do the specifications of the Panasonic GX8 and the Pentax K-5 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GX8 or the K-5. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
