Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot S120 and the Sony Cyber-shot DSC-RX0? 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 Canon S120 and the Sony RX0 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 width, height and depth measures 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 RX0 is considerably smaller (59 percent) than the Canon S120. Moreover, the RX0 is substantially lighter (49 percent) than the S120. It is noteworthy in this context that the RX0 is splash and dust-proof, while the S120 does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.

Concerning battery life, the S120 gets 230 shots out of its Canon NB-6LH battery, while the RX0 can take 240 images on a single charge of its Sony NP-BJ1 power pack. The power pack in the RX0 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.

Any camera decision will naturally be influenced heavily by the price. 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 S120 was launched at a markedly lower price (by 36 percent) than the RX0, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Canon S120 features a 1/1.7-inch sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 is 170 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 2.7. The sensor in the S120 has a native 4:3 aspect ratio, while the one in the RX0 offers a 3:2 aspect.

With 15.4MP, the RX0 offers a higher resolution than the S120 (12MP), but the RX0 nevertheless has larger individual pixels (pixel pitch of 2.74μm versus 1.89μm for the S120) due to its larger sensor. Moreover, the RX0 is a much more recent model (by 4 years) than the S120, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony RX0 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX0 for good quality output (200 dots per inch) amounts to 24 x 16 inches or 61 x 40.6 cm, for very good quality (250 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm, and for excellent quality (300 dpi) 16 x 10.7 inches or 40.6 x 27.1 cm. The corresponding values for the Canon S120 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 Canon PowerShot S120 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0 are ISO 125 to ISO 12800 (no boost).

In terms of underlying technology, the S120 is build around a BSI-CMOS sensor, while the RX0 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the RX0 offers substantially better image quality than the S120 (overall score 12 points higher). The advantage is based on 1.1 bits higher color depth, 0.5 EV in additional dynamic range, and 1.2 stops in additional low light sensitivity. 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The S120 and the RX0 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD.

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 S120 has one, while the RX0 does not. While the built-in flash of the S120 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 RX0 only has 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 Canon S120 has 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.

The S120 is equipped with a zoom lens, while the RX0 comes with a built-in prime. The S120 has a 24-120mm f/1.8-5.7 optic and the RX0 offers a 24mm f/4.0 (focal lengths in full frame equivalent terms). Hence, the Canon and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The S120 offers the faster maximum aperture.

The S120 writes its imaging data to SDXC cards, while the RX0 uses micro SDXC or Memory Stick Micro cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Canon PowerShot S120 and Sony Cyber-shot DSC-RX0 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX0 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The S120 does not feature such a mic input.

Both the S120 and the RX0 have been discontinued, but can regularly be found used on ebay. The RX0 was replaced by the Sony RX0 II, while the S120 does not have a direct successor. Further information on the features and operation of the S120 and RX0 can be found, respectively, in the Canon S120 Manual (free pdf) or the online Sony RX0 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon S120 and the Sony RX0? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon PowerShot S120:

• Larger screen: Has a bigger rear LCD (3.0" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (12.1 vs 5.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/4.0).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in August 2013).

Reasons to prefer the Sony Cyber-shot DSC-RX0:

• More detail: Has more megapixels (15.4 vs 12MP), which boosts linear resolution by 15%.
• Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
• Better low-light sensitivity: Can shoot in dim conditions (1.2 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (59x41mm vs 100x59mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 107g or 49 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 4 years of technical progress since the S120 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the RX0 emerges as the winner of the match-up (13 : 10 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 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 Canon S120 and the Sony RX0 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Prime Lens Compact 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 S120 and the RX0 in practical situations. 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 where reviews by experts come in. 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
