Panasonic GH2 vs Pentax K-1

The Panasonic Lumix DMC-GH2 and the Pentax K-1 are two enthusiast cameras that were announced, respectively, in September 2010 and February 2016. The GH2 is a mirrorless interchangeable lens camera, while the K-1 is a DSLR. The cameras are based on a Four Thirds (GH2) and a full frame (K-1) sensor. The Panasonic has a resolution of 15.9 megapixels, whereas the Pentax provides 36.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GH2 and the Pentax K-1? 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 GH2 and the Pentax K-1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Both cameras are available in two different colors (black, silver).

Size Panasonic GH2 vs Pentax K-1
Compare GH2 versus K-1 top
Comparison GH2 or K-1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 is notably larger (35 percent) than the Panasonic GH2. Moreover, the K-1 is substantially heavier (129 percent) than the GH2. It is noteworthy in this context that the K-1 is splash and dust-proof, while the GH2 does not feature any corresponding weather-sealing.

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 GH2 gets 330 shots out of its DMW-BLC12 battery, while the K-1 can take 760 images on a single charge of its D-LI90 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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

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 GH2 was launched at a markedly lower price (by 50 percent) than the K-1, 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.

Sensor comparison

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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GH2 features a Four Thirds sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 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 GH2 has a native 4:3 aspect ratio, while the one in the K-1 offers a 3:2 aspect.

Panasonic GH2 and Pentax K-1 sensor measures

With 36.2MP, the K-1 offers a higher resolution than the GH2 (15.9MP), but the K-1 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.76μm for the GH2) due to its larger sensor. Moreover, the K-1 is a much more recent model (by 5 years and 4 months) than the GH2, 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 the K-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax K-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Panasonic GH2 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

Unlike the GH2, the K-1 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).

The Panasonic Lumix DMC-GH2 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).

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.

GH2 versus K-1 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-1 offers substantially better image quality than the GH2 (overall score 36 points higher). The advantage is based on 4.2 bits higher color depth, 3.3 EV in additional dynamic range, and 2.3 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.

Note: DXO values in italics represent estimates based on sensor size and age.

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, and both provide the same movie specifications (1080/60i).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH2 has an electronic viewfinder (1534k dots), while the K-1 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 GH2 has a higher magnification than the one of the K-1 (0.71x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Panasonic GH2 and Pentax K-1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The GH2 has one, while the K-1 does not. While the built-in flash of the GH2 is not very powerful, it can at times be useful as a fill-in light.

The GH2 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-1 does not have a selfie-screen.

The Pentax K-1 has 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 GH2 and the K-1 write their files to SDXC cards. The K-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GH2 only has one slot. The K-1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH2 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-GH2 and Pentax K-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the GH2 does not provide wifi capability.

Studio photographers will appreciate that the Pentax K-1 (unlike the GH2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the K-1 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the GH2 and the K-1 have been discontinued, but can regularly be found used on ebay. The GH2 was replaced by the Panasonic GH3, while the K-1 was followed by the Pentax K-1 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Pentax websites.

Review summary

So what is the bottom line? Is there a clear favorite between the Panasonic GH2 and the Pentax K-1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (760 versus 330) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 5 years and 4 months of technical progress since the GH2 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the K-1 is the clear winner of the contest (24 : 10 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GH2 10:24 K-1

How about other alternatives? Do the specifications of the Panasonic GH2 and the Pentax K-1 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 GH2 or the K-1. 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.

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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
