Leica M9 vs Panasonic G9
The Leica M9 and the Panasonic Lumix DC-G9 are two enthusiast cameras that were revealed to the public, respectively, in September 2009 and November 2017. The M9 is a fixed lens compact, while the G9 is a rangefinder-style mirrorless. The cameras are based on a full frame (M9) and a Four Thirds (G9) 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-G9? 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.
An illustration of the physical size and weight of the Leica M9 and the Panasonic G9 is provided 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 measures are rounded to the nearest millimeter.
The M9 can be obtained in two different colors (black, silver), while the G9 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G9 is notably larger (20 percent) than the Leica M9. Moreover, the G9 is markedly heavier (12 percent) than the M9. It is noteworthy in this context that the G9 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 (G9).
The power pack in the G9 can be charged via the USB port, which can be very convenient when travelling.

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 G9 was launched at a markedly lower price (by 79 percent) than the M9, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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 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 G9 a Four Thirds sensor. The sensor area in the G9 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 G9 offers a 4:3 aspect.
Despite having a smaller sensor, the G9 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 G9 is much more recent (by 8 years and 2 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.
Unlike the M9, 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 Leica M9 has a native sensitivity range from ISO 80 to ISO 2500. The corresponding ISO settings for the Panasonic Lumix DC-G9 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 G9 indeed provides for movie recording, while the M9 does not. The highest resolution format that the G9 can use is 4K/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G9 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 G9 has a higher magnification than the one of the M9 (0.83x 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 G9, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9 has a touchscreen, while the M9 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G9 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 G9 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 G9 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 G9 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 M9 only has one slot. The G9 supports UHS-II cards (on both slots), 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-G9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|Olympus E-M1 II||Y||stereo||mono||Y||Y||micro||3.0||Y||-||-|
It is notable that the G9 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 G9 (unlike the M9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The G9 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 how do things add up? Which of the two cameras – the Leica M9 or the Panasonic G9 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Leica M9:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- More compact: Is smaller (139x80mm vs 137x97mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 73g or 11 percent) and hence easier to carry around.
- 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).
Reasons to prefer the Panasonic Lumix DC-G9:
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Broader imaging potential: Can capture not only stills but also 4K/60p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.83x vs 0.68x).
- Easier setting verification: Features a control panel on top to check shooting parameters.

- More modern: Reflects 8 years and 2 months of technical progress since the M9 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the contest (24 : 5 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 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 G9. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.
