Leica SL vs Panasonic GX9

The Leica SL (Typ 601) and the Panasonic Lumix DC-GX9 are two enthusiast cameras that were revealed to the public, respectively, in October 2015 and February 2018. Both the Leica SL and the GX9 are mirrorless interchangeable lens cameras that are based on a full frame (Leica SL) and a Four Thirds (GX9) sensor. The Leica has a resolution of 24 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.

Body comparison

The physical size and weight of the Leica SL 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 views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The GX9 can be obtained in two different colors (black, silver), while the Leica SL is only available in black.

Size Leica SL vs Panasonic GX9
Compare Leica SL versus GX9 top
Comparison Leica SL or GX9 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX9 is considerably smaller (42 percent) than the Leica SL. Moreover, the GX9 is substantially lighter (52 percent) than the Leica SL. It is worth mentioning in this context that the Leica SL is splash and dust resistant, while the GX9 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. Hence, you might want to study and compare 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 Leica SL gets 400 shots out of its Leica BP-SCL4 battery, while the GX9 can take 260 images on a single charge of its Panasonic DMW-BLG10 power pack. 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. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX9 was launched at a markedly lower price (by 89 percent) than the Leica SL, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica SL 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 Leica SL has a native 3:2 aspect ratio, while the one in the GX9 offers a 4:3 aspect.

Leica SL and Panasonic GX9 sensor measures

With 24MP, the Leica SL offers a higher resolution than the GX9 (20.2MP), but the Leica SL nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 3.34μm for the GX9) due to its larger sensor. However, the GX9 is a much more recent model (by 2 years and 3 months) than the Leica SL, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Leica SL implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Leica SL for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic GX9 are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.

The Leica SL (Typ 601) has a native sensitivity range from ISO 50 to ISO 50000. 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Leica SL versus GX9 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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").

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that is present on the Leica SL, but is missing on the GX9 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 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, both cameras under consideration feature an 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 SL and the Panasonic GX9 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 Leica SL and the GX9 write their files to SDXC cards. The Leica SL features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX9 only has one slot. The Leica SL supports UHS-II cards (on its first slot), while the GX9 can use UHS-I cards.

Connectivity comparison

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 SL (Typ 601) 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 Leica SL has a microphone port, which is missing on the GX9. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Leica SL (unlike the GX9) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the Leica SL has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the Leica SL and the GX9 have been discontinued, but can regularly be found used on ebay. The Leica SL was replaced by the Leica SL2, while the GX9 does not have a direct successor. Further information on the features and operation of the Leica SL and GX9 can be found, respectively, in the Leica SL Manual (free pdf) or the online Panasonic GX9 Manual.

ilogo

Advantages of the Panasonic Lumix DC-GX9:

  • More detailed LCD: Has a higher resolution rear screen (1240k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More compact: Is smaller (124x72mm vs 147x104mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 440g or 52 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.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
  • More modern: Reflects 2 years and 3 months of technical progress since the Leica SL launch.

If the count of relative strengths (bullet points above) is taken as a measure, the Leica SL is the clear winner of the match-up (22 : 10 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.

Leica SL 22:10 GX9

How about other alternatives? Do the specifications of the Leica SL and the Panasonic GX9 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the Leica SL and the GX9 in practical situations. 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.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
