Leica CL versus Panasonic GM1
The Leica CL (Typ 7323) and the Panasonic Lumix DMC-GM1 are two digital cameras that were revealed to the public, respectively, in November 2017 and October 2013. Both the CL and the GM1 are mirrorless interchangeable lens cameras that are based on an APS-C (CL) and a Four Thirds sensor. The Leica has a resolution of 24.1 megapixel, whereas the Panasonic provides 15.8 MP.
An illustration of the physical size and weight of the Leica CL and the Panasonic GM1 is provided in the side-by-side display below. 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the CL – represents 100 percent across all the size and weight measures).
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 (47 percent) than the Leica CL. Moreover, the GM1 is substantially lighter (49 percent) than the CL. In this context, it is worth noting that neither the CL nor the GM1 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GM1 was launched at a markedly lower price (by 73 percent) than the CL, 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. 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 tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Leica CL features an APS-C sensor and the Panasonic GM1 a Four Thirds sensor. The sensor area in the GM1 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the CL has a native 3:2 aspect ratio, while the one in the GM1 offers a 4:3 aspect.
With 24.1MP, the CL offers a higher resolution than the GM1 (15.8MP), but the CL nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.77μm for the GM1) due to its larger sensor. Moreover, the CL is a somewhat more recent model (by 4 years and 1 month) than the GM1, and its sensor might 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 CL has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the CL provides a higher video resolution than the GM1. It can shoot video footage at 4K/30p, while the Panasonic is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the CL has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GM1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Leica CL, the Panasonic GM1, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The CL is a current model that online retailers, such as amazon, will have in stock. In contrast, the GM1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the GM1 was succeeded by the Panasonic GM5.
So how do things add up? Which of the two cameras – the Leica CL or the Panasonic GM1 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Leica CL (Typ 7323):
- More detail: Offers more megapixels (24.1 vs 15.8MP) with a 26% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- Easier setting verification: Has an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 500/sec) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More modern: Reflects 4 years and 1 month of technical progress since the GM1 launch.
Reasons to prefer the Panasonic Lumix DMC-GM1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (99x55mm vs 131x78mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 199g or 49 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 (73 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in October 2013).
If the count of individual advantages (bullet points above) is taken as a guide, the CL is the clear winner of the match-up (10 : 6 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the CL or the GM1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
