Leica M9 vs Panasonic GX9
The Leica M9 and the Panasonic Lumix DC-GX9 are two enthusiast cameras that were announced, respectively, in September 2009 and February 2018. The M9 is a fixed lens compact, while the GX9 is a rangefinder-style mirrorless. The cameras are based on a full frame (M9) and a Four Thirds (GX9) sensor. The Leica has a resolution of 18.1 megapixels, whereas the Panasonic provides 20.2 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 Leica M9 and the Panasonic Lumix DC-GX9? 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 physical size and weight of the Leica M9 and the Panasonic GX9 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions 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 GX9 is notably smaller (20 percent) than the Leica M9. Moreover, the GX9 is markedly lighter (30 percent) than the M9. In this context, it is worth noting that neither the M9 nor the GX9 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 (GX9).
The power pack in the GX9 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.

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 GX9 was launched at a markedly lower price (by 89 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and 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 GX9 a Four Thirds sensor. The sensor area in the GX9 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 GX9 offers a 4:3 aspect.
Despite having a smaller sensor, the GX9 offers a higher resolution of 20.2 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 3.34μm versus 6.91μm for the M9). However, it should be noted that the GX9 is much more recent (by 8 years and 5 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 Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Panasonic Lumix DC-GX9 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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GX9 indeed provides for movie recording, while the M9 does not. The highest resolution format that the GX9 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX9 has an electronic viewfinder (2760k 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 GX9 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 adjacent table lists some of the other core features of the Leica M9 and Panasonic GX9 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX9 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 GX9 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 GX9 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 GX9 write their files to SDXC cards. The GX9 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 DC-GX9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX9 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 offer wifi capability.
The GX9 is a recent model that features in the current product line-up of Panasonic. In contrast, the M9 has been discontinued (but it 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 conclusions can be drawn? Is the Leica M9 better than the Panasonic GX9 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Leica M9:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- 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).
Arguments in favor of the Panasonic Lumix DC-GX9:
- Broader imaging potential: Can capture not only stills but also 4K/30p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x 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 (1240k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (9 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.
- More compact: Is smaller (124x72mm vs 139x80mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 178g or 30 percent) and is thus easier to take along.
- Easier travel charging: Can be conveniently charged via its USB port.
- 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.

- More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
- More modern: Reflects 8 years and 5 months of technical progress since the M9 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the GX9 is the clear winner of the contest (19 : 3 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the M9 and the GX9 in practical situations. 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.
This is why expert reviews 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.
Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, please note that some of the review sites have changed their methodology and reporting over time.
