Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot S120 and the Leica X1? 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 Canon S120 and the Leica X1 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 dimensions are rounded to the nearest millimeter.

The X1 can be obtained in two different colors (black, silver), while the S120 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 Leica X1 is notably larger (26 percent) than the Canon S120. Moreover, the X1 is substantially heavier (41 percent) than the S120. In this context, it is worth noting that neither the S120 nor the X1 are weather-sealed.

Concerning battery life, the S120 gets 230 shots out of its Canon NB-6LH battery, while the X1 can take 260 images on a single charge of its Leica BP-DC8 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 77 percent) than the X1, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 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 Leica X1 an APS-C sensor. The sensor area in the X1 is 760 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 1.5. The sensor in the S120 has a native 4:3 aspect ratio, while the one in the X1 offers a 3:2 aspect.

With 12.2MP, the X1 offers a higher resolution than the S120 (12MP), but the X1 nevertheless has larger individual pixels (pixel pitch of 5.51μm versus 1.89μm for the S120) due to its larger sensor. However, the S120 is a much more recent model (by 3 years and 11 months) than the X1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The Canon PowerShot S120 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Leica X1 are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the S120 is build around a BSI-CMOS sensor, while the X1 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. 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. The S120 indeed provides movie recording capabilities, while the X1 does not. The highest resolution format that the S120 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The S120 and the X1 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. The adjacent table lists some of the other core features of the Canon S120 and Leica X1 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The S120 has a touchscreen, while the X1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 X1 comes with a built-in prime. The S120 has a 24-120mm f/1.8-5.7 optic and the X1 offers a 36mm f/2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Leica. The S120 offers the faster maximum aperture.

The S120 writes its imaging data to SDXC cards, while the X1 uses SDHC cards. The S120 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X1 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 Canon PowerShot S120 and Leica X1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S120 offers wifi support, while the X1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the S120 and the X1 have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the S120 does not have a direct successor. Further information on the features and operation of the S120 and X1 can be found, respectively, in the Canon S120 Manual (free pdf) or the online Leica X1 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon S120 and the Leica X1? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot S120:

• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") 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 3 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/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (100x59mm vs 124x60mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 89g or 29 percent) and hence easier to carry around.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
• More modern: Reflects 3 years and 11 months of technical progress since the X1 launch.

Advantages of the Leica X1:

• 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.
• Longer lasting: Gets more shots (260 versus 230) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been around for much longer (launched in September 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the S120 is the clear winner of the match-up (15 : 8 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 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 Canon S120 and the Leica X1 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 X1 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is where reviews by experts come in. 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.

The review scores listed above should be treated 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. 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.
