Body comparison

The side-by-side display below illustrates the physical size and weight of the Panasonic G9 and the Panasonic GM5. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear 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 G9 is only available in black.

Size Panasonic G9 vs Panasonic GM5
Compare G9 versus GM5 top
Comparison G9 or GM5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM5 is considerably smaller (55 percent) than the Panasonic G9. Moreover, the GM5 is substantially lighter (68 percent) than the G9. It is worth mentioning in this context that the G9 is splash and dust resistant, 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available 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.

Concerning battery life, the G9 gets 400 shots out of its Panasonic DMW-BLF19 battery, while the GM5 can take 220 images on a single charge of its Panasonic DMW-BLH7 power pack. The power pack in the G9 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 GM5 was launched at a markedly lower price (by 56 percent) than the G9, 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

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 associated with larger, more expensive camera bodies 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 G9 and Panasonic GM5 sensor measures

While the two cameras under review share the same sensor size, the G9 offers a higher resolution of 20.2 megapixels, compared with 15.8 MP of the GM5. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the G9 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.77μm for the GM5). In this context, it should be noted, however, that the G9 is much more recent (by 3 years and 1 month) than the GM5, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic G9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G9 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 Panasonic GM5 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

Unlike the GM5, the G9 has the capacity to capture high quality composite images (80.6MP) 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 DC-G9 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The Panasonic Lumix DMC-GM5 offers exactly the same ISO settings.

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.

G9 versus GM5 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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.

One feature that is present on the G9, but is missing on the GM5 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The G9 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 GM5 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, both cameras under consideration feature an 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 G9 and the Panasonic GM5 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 G9 and the GM5 write their files to SDXC cards. The G9 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GM5 only has one slot. The G9 supports UHS-II cards (on both slots), while the GM5 can use UHS-I 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 DC-G9 and Panasonic Lumix DMC-GM5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9 has a microphone port, which is missing on the GM5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Panasonic G9 (unlike the GM5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the G9 and the GM5 have been discontinued, but can regularly be found used on ebay. The G9 was replaced by the Panasonic G9 II, while the GM5 does not have a direct successor. Further information on the features and operation of the G9 and GM5 can be found, respectively, in the Panasonic G9 Manual (free pdf) or the online Panasonic GM5 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Panasonic G9 and the Panasonic GM5? Which camera is better? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Panasonic Lumix DC-G9:

  • More detail: Offers more megapixels (20.2 vs 15.8MP) with a 13% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher definition movie capture (4K/60p vs 1080/60p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 1166k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.83x vs 0.46x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/500s) to freeze action.
  • Faster burst: Shoots at higher frequency (20 vs 5.8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (400 versus 220) on a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • 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: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Reflects 3 years and 1 month of technical progress since the GM5 launch.


Reasons to prefer the Panasonic Lumix DMC-GM5:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (99x60mm vs 137x97mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 447g or 68 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (56 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in September 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (25 : 5 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.

G9 25:05 GM5

How about other alternatives? Do the specifications of the Panasonic G9 and the Panasonic GM5 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 incomplete and does no justice, for example, to the way the G9 or the GM5 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.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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