Leica M10 vs Panasonic GM1
The Leica M10 (Typ 3656) and the Panasonic Lumix DMC-GM1 are two digital cameras that were officially introduced, respectively, in January 2017 and October 2013. The M10 is a rangefinder-style mirrorless, while the GM1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (M10) and a Four Thirds (GM1) sensor. The Leica has a resolution of 23.8 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 M10 (Typ 3656) and the Panasonic Lumix DMC-GM1? 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 M10 and the Panasonic GM1 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 dimensions are rounded to the nearest millimeter.
The M10 can be obtained in two different colors (black, silver), while the GM1 is available in three color-versions (black, silver, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM1 is considerably smaller (51 percent) than the Leica M10. Moreover, the GM1 is substantially lighter (69 percent) than the M10. It is worth mentioning in this context that the M10 is splash and dust resistant, while the GM1 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 (M10) and the Micro Four Thirds Lens Catalog (GM1).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The GM1 was launched at a markedly lower price (by 89 percent) than the M10, 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 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 M10 features a full frame sensor and the Panasonic GM1 a Four Thirds sensor. The sensor area in the GM1 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 M10 has a native 3:2 aspect ratio, while the one in the GM1 offers a 4:3 aspect.
With 23.8MP, the M10 offers a higher resolution than the GM1 (15.8MP), but the M10 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 3.77μm for the GM1) due to its larger sensor. Moreover, the M10 is a much more recent model (by 3 years and 3 months) than the GM1, 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 the M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Leica M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M10 for good quality output (200 dots per inch) amounts to 29.8 x 20 inches or 75.6 x 50.7 cm, for very good quality (250 dpi) 23.8 x 16 inches or 60.5 x 40.6 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.8 cm. The corresponding values for the Panasonic GM1 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 M10 (Typ 3656) has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Panasonic Lumix DMC-GM1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 125-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the M10 provides substantially higher image quality than the GM1, with an overall score that is 20 points higher. This advantage is based on 2.1 bits higher color depth, 1.5 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The GM1 indeed provides for movie recording, while the M10 does not. The highest resolution format that the GM1 can use is 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the M10 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GM1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Leica M10 and Panasonic GM1 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 GM1 has a touchscreen, while the M10 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 GM1 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 Leica M10 and the Panasonic GM1 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 M10 and the GM1 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 M10 (Typ 3656) and Panasonic Lumix DMC-GM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M10 has a hotshoe, while the GM1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The M10 is a recent model that features in the current product line-up of Leica. In contrast, the GM1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GM1 was succeeded by the Panasonic GM5. 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? Which of the two cameras – the Leica M10 or the Panasonic GM1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Advantages of the Leica M10 (Typ 3656):
- More detail: Offers more megapixels (23.8 vs 15.8MP) with a 25% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (20 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.1 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1.5 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.7 stops ISO advantage).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More modern: Reflects 3 years and 3 months of technical progress since the GM1 launch.
Arguments in favor of the Panasonic Lumix DMC-GM1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (99x55mm vs 139x80mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 456g or 69 percent) and is thus easier to take along.
- 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 heavily discounted: Has been around for much longer (launched in October 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the M10 emerges as the winner of the contest (12 : 9 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M10 or the GM1. 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 (amateurphotographer [AP], cameralabs [CL], 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
