Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G12 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 G12 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 G12 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 (13 percent) than the Canon G12. Moreover, the X1 is markedly lighter (24 percent) than the G12. In this context, it is worth noting that neither the G12 nor the X1 are weather-sealed.

Concerning battery life, the G12 gets 370 shots out of its Canon NB-7L 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G12 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 imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G12 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 G12 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 G12 (10MP), but the X1 nevertheless has larger individual pixels (pixel pitch of 5.51μm versus 2.07μm for the G12) due to its larger sensor. However, the G12 is a somewhat more recent model (by 1 year) than the X1, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Leica X1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X1 for good quality output (200 dots per inch) amounts to 21.4 x 14.3 inches or 54.3 x 36.3 cm, for very good quality (250 dpi) 17.1 x 11.4 inches or 43.4 x 29 cm, and for excellent quality (300 dpi) 14.2 x 9.5 inches or 36.2 x 24.2 cm. The corresponding values for the Canon G12 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Canon PowerShot G12 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Leica X1 are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the G12 is build around a CCD 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 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 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 G12 indeed provides movie recording capabilities, while the X1 does not. The highest resolution format that the G12 can use is 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G12 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 G12, the Leica X1, and comparable cameras.

The G12 is equipped with a zoom lens, while the X1 comes with a built-in prime. The G12 has a 28-140mm f/2.8-4.5 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. Both cameras offer the same maximum aperture.

The G12 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 G12 and Leica X1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G12 and the X1 have been discontinued, but can regularly be found used on ebay. The X1 was replaced by the Leica X2, while the G12 was followed by the Canon G15. Further information on the features and operation of the G12 and X1 can be found, respectively, in the Canon G12 Manual (free pdf) or the online Leica X1 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon G12 or the Leica X1 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon PowerShot G12:

• Broader imaging potential: Can record not only still images but also 720/24p movies.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (2.8" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (461k vs 230k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Longer lasting: Can take more shots (370 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: Is somewhat more recent (announced 1 year after the X1).

Reasons to prefer the Leica X1:

• More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 13%.
• 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 1.1 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (124x60mm vs 112x76mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 95g or 24 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 on the market for longer (launched in September 2009).

If the count of relative strengths (bullet points above) is taken as a measure, the G12 comes out slightly ahead of the X1 (11 : 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 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 G12 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G12 or the X1 perform in practice. 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 expert reviews 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
