Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G15 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 G15 and the Leica X1 is provided 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.

The X1 can be obtained in two different colors (black, silver), while the G15 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 smaller (9 percent) than the Canon G15. Moreover, the X1 is markedly lighter (13 percent) than the G15. In this context, it is worth noting that neither the G15 nor the X1 are weather-sealed.

Concerning battery life, the G15 gets 350 shots out of its Canon NB-10L battery, while the X1 can take 260 images on a single charge of its Leica BP-DC8 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G15 was launched at a markedly lower price (by 75 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.

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G15 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, 4.6 and 1.5. The sensor in the G15 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 G15 (12MP), but the X1 nevertheless has larger individual pixels (pixel pitch of 5.51μm versus 1.89μm for the G15) due to its larger sensor. However, the G15 is a much more recent model (by 3 years) 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 G15 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).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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 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. The G15 indeed provides movie recording capabilities, while the X1 does not. The highest resolution format that the G15 can use is 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G15 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G15, the Leica X1, and comparable cameras.

The G15 is equipped with a zoom lens, while the X1 comes with a built-in prime. The G15 has a 28-140mm f/1.8-2.8 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 G15 offers the faster maximum aperture.

The G15 writes its imaging data to SDXC cards, while the X1 uses SDHC 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 G15 and Leica X1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G15 and the X1 have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the G15 was followed by the Canon G16. Further information on the features and operation of the G15 and X1 can be found, respectively, in the Canon G15 Manual (free pdf) or the online Leica X1 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon G15 and the Leica X1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon PowerShot G15:

• Broader imaging potential: Can record not only still images but also 1080/24p movies.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• 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.
• Longer lasting: Can take more shots (350 versus 260) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
• More modern: Reflects 3 years of technical progress since the X1 launch.

Arguments in favor 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.
• Faster burst: Shoots at higher frequency (3 vs 2.1 flaps/sec) to capture the decisive moment.
• Less heavy: Has a lower weight (by 46g or 13 percent) and is thus easier to take along.
• 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 G15 emerges as the winner of the contest (11 : 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 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 Canon G15 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G15 and the X1 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 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.

Care should be taken when interpreting the review scores above, 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 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.
