Leica CL versus Panasonic GM1

The Leica CL (Typ 7323) and the Panasonic Lumix DMC-GM1 are two digital cameras that were officially introduced, 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 (GM1) sensor. The Leica has a resolution of 24.1 megapixel, whereas the Panasonic provides 15.8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Leica CL vs Panasonic GM1

The side-by-side display below illustrates the physical size and weight of the Leica CL and the Panasonic GM1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions 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.

Concerning battery life, the CL gets 220 shots out of its BP-DC12 battery, while the GM1 can take 230 images on a single charge of its DMW-BLH7 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera.

Any camera purchase will naturally be influenced heavily by the price. 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 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.

 

Sensor comparison: Leica CL vs Panasonic GM1

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Leica CL and Panasonic GM1 sensor measures

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.

CL versus GM1 MP

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, 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.

 

Feature comparison: Leica CL vs Panasonic GM1

Apart from body and sensor, cameras can and do differ across a variety 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 adjacent table lists some of the other core features of the Leica CL and Panasonic GM1 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that is present on the CL, but is missing on the GM1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the CL and the GM1 write their imaging data to SDXC cards.

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.

Review summary: Leica CL vs Panasonic GM1

So what conclusions can be drawn? Is there a clear favorite between the Leica CL and the Panasonic GM1? A synthesis of the relative strong points of each of the models is listed below.

ilogo

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: Features 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.
  • 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 4 years and 1 month of technical progress since the GM1 launch.

ilogo

Advantages of 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 (11 : 6 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.

CL 11:06 GM1

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the CL or the GM1 handle or perform in practice. 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 hands-on reviews by experts are important.

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