Going beyond this snapshot of core features and characteristics, what are the differences between the Leica S3 and the Panasonic Lumix DMC-GH1? 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.

Body comparison

An illustration of the physical size and weight of the Leica S3 and the Panasonic GH1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The GH1 can be obtained in two different colors (black, red), while the S3 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 GH1 is considerably smaller (42 percent) than the Leica S3. Moreover, the GH1 is substantially lighter (69 percent) than the S3. It is worth mentioning in this context that the S3 is splash and dust resistant, while the GH1 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 S3 gets .. shots out of its Leica BP-PRO1 battery, while the GH1 can take 300 images on a single charge of its Panasonic DMW-BLB13 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 GH1 was launched at a markedly lower price (by 95 percent) than the S3, 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 size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 S3 features a medium format sensor and the Panasonic GH1 a Four Thirds sensor. The sensor area in the GH1 is 83 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.8 and 2.0. The sensor in the S3 has a native 3:2 aspect ratio, while the one in the GH1 offers a 4:3 aspect.

With 64MP, the S3 offers a higher resolution than the GH1 (12MP), but the S3 nevertheless has larger individual pixels (pixel pitch of 4.59μm versus 4.33μm for the GH1) due to its larger sensor. Moreover, the S3 is a much more recent model (by 9 years and 6 months) than the GH1, 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 S3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica S3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S3 for good quality output (200 dots per inch) amounts to 49 x 32.7 inches or 124.5 x 83 cm, for very good quality (250 dpi) 39.2 x 26.1 inches or 99.6 x 66.4 cm, and for excellent quality (300 dpi) 32.7 x 21.8 inches or 83 x 55.3 cm. The corresponding values for the Panasonic GH1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Leica S3 has a native sensitivity range from ISO 100 to ISO 50000. The corresponding ISO settings for the Panasonic Lumix DMC-GH1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 have a sensor with sufficiently fast read-out times for moving pictures, but the S3 provides a higher video resolution than the GH1. It can shoot video footage at 4K/24p, while the Panasonic is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the GH1 has an electronic viewfinder (1440k dots), while the S3 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 viewfinder in the GH1 offers a wider field of view (100%) than the one in the S3 (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the S3 has a higher magnification (0.87x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Leica S3 and Panasonic GH1 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the S3, but is missing on the GH1 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 S3 writes its imaging data to Compact Flash or SDXC cards, while the GH1 uses SDHC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GH1 only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the GH1 cannot take advantage of Ultra High Speed SD 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 S3 and Panasonic Lumix DMC-GH1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S3 has a headphone jack, which is not present on the GH1 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Leica S3 (unlike the GH1) 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 S3 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the S3 and the GH1 have been discontinued, but can regularly be found used on ebay. The GH1 was replaced by the Panasonic GH2, while the S3 does not have a direct successor. Further information on the features and operation of the S3 and GH1 can be found, respectively, in the Leica S3 Manual (free pdf) or the online Panasonic GH1 Manual.

If the number of relative strengths (bullet points above) is taken as a guide, the S3 is the clear winner of the match-up (21 : 11 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.

How about other alternatives? Do the specifications of the Leica S3 and the Panasonic GH1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the S3 and the GH1 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
