Going beyond this snapshot of core features and characteristics, what are the differences between the Leica S3 and the Panasonic Lumix DMC-G2? 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.
The physical size and weight of the Leica S3 and the Panasonic G2 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 G2 can be obtained in three different colors (black, blue, 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 G2 is considerably smaller (46 percent) than the Leica S3. Moreover, the G2 is substantially lighter (66 percent) than the S3. It is worth mentioning in this context that the S3 is splash and dust resistant, while the G2 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G2 was launched at a markedly lower price (by 97 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.
The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to 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 G2 a Four Thirds sensor. The sensor area in the G2 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 G2 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 64MP, the S3 offers a higher resolution than the G2 (12MP), but the S3 nevertheless has larger individual pixels (pixel pitch of 4.59μm versus 4.33μm for the G2) due to its larger sensor. Moreover, the S3 is a much more recent model (by 8 years and 6 months) than the G2, 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 G2 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-G2 are ISO 100 to ISO 6400 (no boost).
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"). 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the S3 provides a higher video resolution than the G2. It can shoot video footage at 4K/24p, while the Panasonic is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G2 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 G2 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 adjacent table lists some of the other core features of the Leica S3 and Panasonic G2 along with similar information for a selection of comparators.

One feature that is present on the S3, but is missing on the G2 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 G2 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the S3 does not have a selfie-screen.
The S3 writes its imaging data to Compact Flash or SDXC cards, while the G2 uses SDXC cards. The S3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G2 only has one slot. The S3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G2 cannot take advantage of Ultra High Speed SD cards.
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-G2 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 microphone port, which is missing on the G2. 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 S3 (unlike the G2) 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.
The S3 is a recent model that features in the current product line-up of Leica. In contrast, the G2 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the G2 was succeeded by the Panasonic G3. 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? Is the Leica S3 better than the Panasonic G2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

- Less heavy: Has a lower weight (by 832g or 66 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (97 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in March 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the S3 is the clear winner of the match-up (23 : 12 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 when reflecting and deciding 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.
How about other alternatives? Do the specifications of the Leica S3 and the Panasonic G2 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 G2 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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.
