Leica M9 vs Panasonic GX80
The Leica M9 and the Panasonic Lumix DMC-GX80 (labelled Panasonic GX85 in some countries) are two digital cameras that were announced, respectively, in September 2009 and April 2016. The M9 is a fixed lens compact, while the GX80 is a rangefinder-style mirrorless. The cameras are based on a full frame (M9) and a Four Thirds (GX80) sensor. The Leica has a resolution of 18.1 megapixels, whereas the Panasonic provides 15.8 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 Leica M9 and the Panasonic Lumix DMC-GX80? 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.
The side-by-side display below illustrates the physical size and weight of the Leica M9 and the Panasonic GX80. 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 measures are rounded to the nearest millimeter.
Both cameras are available in two different colors (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX80 is notably smaller (22 percent) than the Leica M9. Moreover, the GX80 is markedly lighter (27 percent) than the M9. In this context, it is worth noting that neither the M9 nor the GX80 are weather-sealed.
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 (GX80).

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX80 was launched at a markedly lower price (by 90 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Leica M9 features a full frame sensor and the Panasonic GX80 a Four Thirds sensor. The sensor area in the GX80 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 GX80 offers a 4:3 aspect.
With 18.1MP, the M9 offers a higher resolution than the GX80 (15.8MP), but the M9 nevertheless has larger individual pixels (pixel pitch of 6.91μm versus 3.77μm for the GX80) due to its larger sensor. However, the GX80 is a much more recent model (by 6 years and 6 months) than the M9, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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 Leica M9 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M9 for good quality output (200 dots per inch) amounts to 26.1 x 17.4 inches or 66.2 x 44.1 cm, for very good quality (250 dpi) 20.8 x 13.9 inches or 53 x 35.3 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.1 x 29.4 cm. The corresponding values for the Panasonic GX80 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.
The Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Panasonic Lumix DMC-GX80 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 also of capturing video footage. The GX80 indeed provides for movie recording, while the M9 does not. The highest resolution format that the GX80 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX80 has an electronic viewfinder (2765k 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 GX80 has a higher magnification than the one of the M9 (0.70x vs 0.68x), 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 Leica M9, the Panasonic GX80, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX80 has a touchscreen, while the M9 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 GX80 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 GX80 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 M9 and the GX80 write their files to SDXC cards. The GX80 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the M9 cannot take advantage of Ultra High Speed SD cards.
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 Leica M9 and Panasonic Lumix DMC-GX80 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX80 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.
The GX80 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.
So what is the bottom line? Is there a clear favorite between the Leica M9 and the Panasonic GX80? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Leica M9:
- More detail: Offers more megapixels (18.1 vs 15.8MP) with a 9% higher linear resolution.

If the count of individual advantages (bullet points above) is taken as a guide, the GX80 is the clear winner of the contest (19 : 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.
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 M9 or the GX80. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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 (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.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
