Going beyond this snapshot of core features and characteristics, what are the differences between the Leica S2 and the Leica V-LUX 3? 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

The physical size and weight of the Leica S2 and the Leica V-LUX 3 are illustrated 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 dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica V-LUX 3 is considerably smaller (48 percent) than the Leica S2. It is worth mentioning in this context that the S2 is splash and dust resistant, while the V-LUX 3 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the V-LUX 3 has a lens built in, whereas the S2 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the S2 gets .. shots out of its Leica BP-PRO1 battery, while the V-LUX 3 can take 410 images on a single charge of its Leica BP-DC9 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. 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 V-LUX 3 was launched at a lower price than the S2, despite having a lens built in. 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 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. 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 S2 features a medium format sensor and the Leica V-LUX 3 a 1/2.3-inch sensor. The sensor area in the V-LUX 3 is 98 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.8 and 5.6. The sensor in the S2 has a native 3:2 aspect ratio, while the one in the V-LUX 3 offers a 4:3 aspect.

With 37.5MP, the S2 offers a higher resolution than the V-LUX 3 (12MP), but the S2 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 1.53μm for the V-LUX 3) due to its larger sensor. However, the V-LUX 3 is a much more recent model (by 3 years and 2 months) than the S2, 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 S2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S2 for good quality output (200 dots per inch) amounts to 37.5 x 25 inches or 95.3 x 63.5 cm, for very good quality (250 dpi) 30 x 20 inches or 76.2 x 50.8 cm, and for excellent quality (300 dpi) 25 x 16.7 inches or 63.5 x 42.3 cm. The corresponding values for the Leica V-LUX 3 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 S2 has a native sensitivity range from ISO 80 to ISO 1250. The corresponding ISO settings for the Leica V-LUX 3 are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

In terms of underlying technology, the S2 is build around a CCD sensor, while the V-LUX 3 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The V-LUX 3 indeed provides for movie recording, while the S2 does not. The highest resolution format that the V-LUX 3 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the V-LUX 3 has an electronic viewfinder (202k dots), while the S2 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 following table reports on some other key feature differences and similarities of the Leica S2, the Leica V-LUX 3, and comparable cameras.

One feature that is present on the S2, but is missing on the V-LUX 3 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 S2 writes its imaging data to Compact Flash or SDHC cards, while the V-LUX 3 uses SDXC cards. The S2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the V-LUX 3 only has one slot.

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 S2 and Leica V-LUX 3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Leica S2 (unlike the V-LUX 3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the S2 and the V-LUX 3 have been discontinued, but can regularly be found used on ebay. The S2 was replaced by the Leica S Typ 006, while the V-LUX 3 was followed by the Leica V-LUX 4. Further information on the features and operation of the S2 and V-LUX 3 can be found, respectively, in the Leica S2 Manual (free pdf) or the online Leica V-LUX 3 Manual.

Review summary

So how do things add up? Is the Leica S2 better than the Leica V-LUX 3 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Leica S2:

• More detail: Offers more megapixels (37.5 vs 12MP) with a 80% higher linear resolution.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in September 2008).

Reasons to prefer the Leica V-LUX 3:

• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (12 vs 1.5 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with an integrated lens, while the S2 requires a separate lens.
• More compact: Is smaller (124x81mm vs 160x120mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the S2).
• 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.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 3 years and 2 months of technical progress since the S2 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the S2 comes out slightly ahead of the V-LUX 3 (13 : 12 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 S2 and the Leica V-LUX 3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the S2 and the V-LUX 3 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 following table reports the overall ratings of the cameras as published by some of the major 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.

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. 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.
