Going beyond this snapshot of core features and characteristics, what are the differences between the Leica S2 and the Sony Cyber-shot DSC-RX10 II? 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 Sony RX10 II are illustrated in the side-by-side display below. 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 the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 II is considerably smaller (41 percent) than the Leica S2. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 II 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 RX10 II can take 400 images on a single charge of its Sony NP-FW50 power pack. The power pack in the RX10 II can be charged via the USB port, which can be very convenient when travelling.

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

Convert to Imperial

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 RX10 II was launched at a lower price than the S2, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Leica S2 features a medium format sensor and the Sony RX10 II an one-inch sensor. The sensor area in the RX10 II is 91 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 0.8 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 37.5MP, the S2 offers a higher resolution than the RX10 II (20MP), but the S2 nevertheless has larger individual pixels (pixel pitch of 6.00μm versus 2.41μm for the RX10 II) due to its larger sensor. However, the RX10 II is a much more recent model (by 6 years and 8 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 the S2 has no anti-alias filter installed, so that it can capture all the detail its 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 Sony RX10 II are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 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 Sony Cyber-shot DSC-RX10 II are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.

In terms of underlying technology, the S2 is build around a CCD sensor, while the RX10 II uses a BSI-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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The RX10 II indeed provides for movie recording, while the S2 does not. The highest resolution format that the RX10 II can use is 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX10 II has an electronic viewfinder (2359k 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 viewfinder in the RX10 II offers a wider field of view (100%) than the one in the S2 (96%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the S2 has a higher magnification (0.86x 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 S2 and Sony RX10 II in connection with corresponding information for a sample of similar cameras.

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

One difference between the cameras concerns the presence of an on-board flash. The RX10 II has one, while the S2 does not. While the built-in flash of the RX10 II is not very powerful, it can at times be useful as a fill-in light.

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, the RX10 II is one of those camera that have an additional 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 S2 writes its imaging data to Compact Flash or SDHC cards, while the RX10 II uses SDXC or Memory Stick PRO Duo cards. The S2 features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX10 II only has one slot. The RX10 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the S2 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 S2 and Sony Cyber-shot DSC-RX10 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the S2 does not provide wifi capability.

Studio photographers will appreciate that the Leica S2 (unlike the RX10 II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the S2 and the RX10 II have been discontinued, but can regularly be found used on ebay. The S2 was replaced by the Leica S Typ 006, while the RX10 II was followed by the Sony RX10 III. Further information on the features and operation of the S2 and RX10 II can be found, respectively, in the Leica S2 Manual (free pdf) or the online Sony RX10 II Manual.

Review summary

So how do things add up? Is the Leica S2 better than the Sony RX10 II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Leica S2:

• More detail: Offers more megapixels (37.5 vs 20MP) with a 37% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.

Advantages of the Sony Cyber-shot DSC-RX10 II:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
• More detailed LCD: Has a higher resolution rear screen (1229k vs 460k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (14 vs 1.5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Comes with an integrated lens, while the S2 requires a separate lens.
• More compact: Is smaller (129x88mm 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).

If the count of individual advantages (bullet points above) is taken as a guide, the RX10 II is the clear winner of the contest (19 : 10 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Sony RX10 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 remains incomplete and does no justice, for example, to the way the S2 or the RX10 II perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
