Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GM5 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 physical size and weight of the Panasonic GM5 and the Pentax K-5 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. 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.

The GM5 can be obtained in two different colors (black, silver), while the K-5 is only available in black.

Size Panasonic GM5 vs Pentax K-5
Compare GM5 versus K-5 top
Comparison GM5 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 considerably larger (114 percent) than the Panasonic GM5. Moreover, the K-5 is substantially heavier (260 percent) than the GM5. It is noteworthy in this context that the K-5 is splash and dust-proof, while the GM5 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 GM5 gets 220 shots out of its DMW-BLH7 battery, while the K-5 can take 740 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 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.

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

Any camera decision will naturally be influenced heavily by the price. 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 GM5 was launched at a markedly lower price (by 32 percent) than the K-5, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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. 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 GM5 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 GM5 has a native 4:3 aspect ratio, while the one in the K-5 offers a 3:2 aspect.

Panasonic GM5 and Pentax K-5 sensor measures

With 16.1MP, the K-5 offers a higher resolution than the GM5 (15.8MP), but the K-5 nevertheless has larger individual pixels (pixel pitch of 4.81μm versus 3.77μm for the GM5) due to its larger sensor. However, the GM5 is a much more recent model (by 3 years and 11 months) than the K-5, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The Panasonic Lumix DMC-GM5 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.

GM5 versus K-5 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. Of the two cameras under consideration, the K-5 offers substantially better image quality than the GM5 (overall score 16 points higher). The advantage is based on 1.6 bits higher color depth, 2.4 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GM5 provides a higher frame rate than the K-5. It can shoot video footage at 1080/60p, 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 GM5 has an electronic viewfinder (1166k 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 K-5 has a higher magnification than the one of the GM5 (0.61x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Panasonic GM5, the Pentax K-5, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GM5 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 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 GM5 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 GM5 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 GM5 and the K-5 write their files to SDXC cards. The GM5 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-GM5 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 GM5 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 GM5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GM5 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 GM5 does not have a direct successor. 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 how do things add up? Is the Panasonic GM5 better than the Pentax K-5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Panasonic Lumix DMC-GM5:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/25p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (99x60mm vs 131x97mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 549g or 72 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was introduced into a lower priced category (32 percent cheaper at launch).
  • More modern: Reflects 3 years and 11 months of technical progress since the K-5 launch.

ilogo

Reasons to prefer the Pentax K-5:

  • Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.6 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.4 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.61x vs 0.46x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/500s) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 5.8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (740 versus 220) 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 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 count of relative strengths (bullet points above) is taken as a measure, the K-5 is the clear winner of the contest (16 : 11 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

GM5 11:16 K-5

How about other alternatives? Do the specifications of the Panasonic GM5 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GM5 or the K-5. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
