Leica M9 vs Panasonic GH7

The Leica M9 and the Panasonic Lumix DC-GH7 are two enthusiast cameras that were announced, respectively, in September 2009 and June 2024. The M9 is a rangefinder-focusing mirrorless, while the GH7 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (M9) and a Four Thirds (GH7) sensor. The Leica has a resolution of 18.1 megapixels, whereas the Panasonic provides 25 MP.

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

Body comparison

The side-by-side display below illustrates the physical size and weight of the Leica M9 and the Panasonic GH7. 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.

The M9 can be obtained in two different colors (black, silver), while the GH7 is only available in black.

Size Leica M9 vs Panasonic GH7
Compare M9 versus GH7 top
Comparison M9 or GH7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH7 is notably larger (24 percent) than the Leica M9. Moreover, the GH7 is substantially heavier (38 percent) than the M9. It is noteworthy in this context that the GH7 is splash and dust-proof, while the M9 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Leica M Lens Catalog (M9) and the Micro Four Thirds Lens Catalog (GH7).

Concerning battery life, the M9 gets 550 shots out of its Leica BLI-312 battery, while the GH7 can take 380 images on a single charge of its Panasonic DMW-BLK23 power pack. The power pack in the GH7 can be charged via the USB port, which can be very convenient when travelling.

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 GH7 was launched at a markedly lower price (by 73 percent) than the M9, 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. 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.

Of the two cameras under consideration, the Leica M9 features a full frame sensor and the Panasonic GH7 a Four Thirds sensor. The sensor area in the GH7 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the M9 has a native 3:2 aspect ratio, while the one in the GH7 offers a 4:3 aspect.

Leica M9 and Panasonic GH7 sensor measures

Despite having a smaller sensor, the GH7 offers a higher resolution of 25 megapixels, compared with 18.1 MP of the M9. 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 3.00μm versus 6.91μm for the M9). However, it should be noted that the GH7 is much more recent (by 14 years and 8 months) than the M9, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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.

The resolution advantage of the Panasonic GH7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GH7 for good quality output (200 dots per inch) amounts to 28.9 x 21.7 inches or 73.4 x 55.1 cm, for very good quality (250 dpi) 23.1 x 17.3 inches or 58.7 x 44.1 cm, and for excellent quality (300 dpi) 19.3 x 14.5 inches or 48.9 x 36.7 cm. The corresponding values for the Leica M9 are 26.1 x 17.4 inches or 66.2 x 44.1 cm for good quality, 20.8 x 13.9 inches or 53 x 35.3 cm for very good quality, and 17.4 x 11.6 inches or 44.1 x 29.4 cm for excellent quality prints.

The GH7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the M9, the GH7 has the capacity to capture high quality composite images (100MP) 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 Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Panasonic Lumix DC-GH7 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.

In terms of underlying technology, the M9 is build around a CCD sensor, while the GH7 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

M9 versus GH7 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH7 has an electronic viewfinder (3680k dots), while the M9 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 GH7 has a higher magnification than the one of the M9 (0.8x vs 0.68x), 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 Leica M9 and Panasonic GH7 in connection with corresponding information for a sample of similar cameras.

Note: *) 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 GH7 has a touchscreen, while the M9 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The GH7 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the M9 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 GH7 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 GH7 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.

The M9 writes its imaging data to SDXC cards, while the GH7 uses CFexpress (type B) or SDXC cards. The GH7 features dual card slots, which can be very useful in case a memory card fails. In contrast, the M9 only has one slot. The GH7 supports UHS-II cards (on both slots), while the M9 cannot take advantage of Ultra High Speed SD cards.

It is notable that the GH7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the M9 does not provide wifi capability.

Studio photographers will appreciate that the Panasonic GH7 (unlike the M9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The GH7 is a recent model that features in the current product line-up of Panasonic. In contrast, the M9 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the M9 was succeeded by the Leica M Typ 240. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Leica and Panasonic websites.

Review summary

So how do things add up? Is there a clear favorite between the Leica M9 and the Panasonic GH7? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Leica M9:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More compact: Is smaller (139x80mm vs 138x100mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 220g or 27 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (550 versus 380) on a single battery charge.
  • More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
  • More heavily discounted: Has been available for much longer (launched in September 2009).

ilogo

Advantages of the Panasonic Lumix DC-GH7:

  • More detail: Has more megapixels (25 vs 18.1MP), which boosts linear resolution by 15%.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Broader imaging potential: Can capture not only stills but also 5.7K/60p video.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.8x vs 0.68x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1840k vs 230k dots).
  • More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • 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 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (14 vs 2 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.

  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • 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 Ultra High Speed (UHS-II) SDXC cards on both slots.
  • More affordable: Was introduced into a lower priced category (73 percent cheaper at launch).
  • More modern: Reflects 14 years and 8 months of technical progress since the M9 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the GH7 is the clear winner of the contest (26 : 6 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.

M9 06:26 GH7

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 M9 or the GH7. 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.

Note: (+ +) 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.
