Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 10D and the Leica X2? 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 10D and the Leica X2 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 dimensions are rounded to the nearest millimeter.

The X2 can be obtained in two different colors (black, silver), while the 10D 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 X2 is considerably smaller (47 percent) than the Canon 10D. In this context, it is worth noting that neither the 10D nor the X2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X2 has a lens built in, whereas the 10D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 10D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 10D gets 500 shots out of its Canon BP-511 battery, while the X2 can take 450 images on a single charge of its Leica BP-DC8 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the X2 is 8 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (10D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 16.1MP, the X2 offers a higher resolution than the 10D (6.3MP), but the X2 has smaller individual pixels (pixel pitch of 4.79μm versus 7.38μm for the 10D). Yet, the X2 is a much more recent model (by 9 years and 2 months) than the 10D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Leica X2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X2 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inches or 39 x 26 cm for good quality, 12.3 x 8.2 inches or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inches or 26 x 17.3 cm for excellent quality prints.

The Canon EOS 10D has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Leica X2 are ISO 100 to ISO 12500 (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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 10D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the X2 relies on live view and the rear LCD for framing. That said, the X2 can be equipped with an optional viewfinder – the EVF 2. The following table reports on some other key feature differences and similarities of the Canon 10D, the Leica X2, and comparable cameras.

One feature that is present on the 10D, but is missing on the X2 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The 10D writes its imaging data to Compact Flash cards, while the X2 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 EOS 10D and Leica X2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 10D (unlike the X2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 10D and the X2 have been discontinued, but can regularly be found used on ebay. The 10D was replaced by the Canon 20D, while the X2 does not have a direct successor. Further information on the features and operation of the 10D and X2 can be found, respectively, in the Canon 10D Manual (free pdf) or the online Leica X2 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 10D and the Leica X2? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon EOS 10D:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (500 versus 450) on a single battery charge.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in February 2003).

Reasons to prefer the Leica X2:

• More detail: Has more megapixels (16.1 vs 6.3MP), which boosts linear resolution by 60%.
• Larger screen: Has a bigger rear LCD (2.7" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 118k dots).
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with an integrated lens, while the 10D requires a separate lens.
• More compact: Is smaller (124x69mm vs 150x107mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 10D).
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Reflects 9 years and 2 months of technical progress since the 10D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the X2 emerges as the winner of the match-up (10 : 7 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 10D and the Leica X2 place the cameras among the top in their class? Find out in the latest Best DSLR 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 10D and the X2 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 why hands-on reviews by experts are important. 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.

Care should be taken when interpreting the review scores above, 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
