Canon 10D vs Leica Digilux 3

The Canon EOS 10D and the Leica Digilux 3 are two digital cameras that were officially introduced, respectively, in February 2003 and September 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (10D) and a Four Thirds (Digilux 3) sensor. The Canon has a resolution of 6.3 megapixels, whereas the Leica provides 7.4 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 10D and the Leica Digilux 3? 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 side-by-side display below illustrates the physical size and weight of the Canon 10D and the Leica Digilux 3. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Canon 10D vs Leica Digilux 3
Compare 10D versus Digilux 3 top
Comparison 10D or Digilux 3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Leica Digilux 3 is notably smaller (21 percent) than the Canon 10D. Moreover, the Digilux 3 is markedly lighter (29 percent) than the 10D. In this context, it is worth noting that neither the 10D nor the Digilux 3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (10D) and the Four Thirds Lens Catalog (Digilux 3).

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, just use the right or left arrows in the table to switch to the respective camera.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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. The Digilux 3 was launched at a somewhat lower price (by 25 percent) than the 10D, which makes it more attractive for photographers on a tight budget. 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. 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 10D features an APS-C sensor and the Leica Digilux 3 a Four Thirds sensor. The sensor area in the Digilux 3 is 34 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 10D has a native 3:2 aspect ratio, while the one in the Digilux 3 offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon 10D and Leica Digilux 3 sensor measures

Despite having a smaller sensor, the Digilux 3 offers a higher resolution of 7.4 megapixels, compared with 6.3 MP of the 10D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.51μm versus 7.38μm for the 10D). However, it should be noted that the Digilux 3 is much more recent (by 3 years and 6 months) than the 10D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Leica Digilux 3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Digilux 3 for good quality output (200 dots per inch) amounts to 15.7 x 11.8 inch or 39.8 x 29.9 cm, for very good quality (250 dpi) 12.5 x 9.4 inch or 31.9 x 23.9 cm, and for excellent quality (300 dpi) 10.5 x 7.8 inch or 26.6 x 19.9 cm. The corresponding values for the Canon 10D are 15.4 x 10.2 inch or 39 x 26 cm for good quality, 12.3 x 8.2 inch or 31.2 x 20.8 cm for very good quality, and 10.2 x 6.8 inch 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 Digilux 3 are ISO 100 to ISO 1600 (no boost).

The Digilux 3 offers Live View, so that it can project the live image that the sensor receives onto the rear screen for framing. The 10D lacks this capability. Both cameras are still-image focused and cannot record videos.
 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 10D and the Digilux 3 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 10D has a higher magnification than the one of the Digilux 3 (0.55x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 10D and Leica Digilux 3 along with similar information for a selection of comparators.

One feature that is present on the 10D, but is missing on the Digilux 3 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 Digilux 3 uses SDXC cards.

Studio photographers will appreciate that the Canon 10D (unlike the Digilux 3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 10D and the Digilux 3 have been discontinued, but can regularly be found used on eBay. The 10D was replaced by the Canon 20D, while the Digilux 3 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.


Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 10D and the Leica Digilux 3? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Canon EOS 10D:

  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.55x vs 0.47x).
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • 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).

ilogo

Arguments in favor of the Leica Digilux 3:

  • More detail: Has more megapixels (7.4 vs 6.3MP), which boosts linear resolution by 6%.
  • Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (207k vs 118k dots).
  • More compact: Is smaller (146x87mm vs 150x107mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 244g or 29 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
  • 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 affordable: Was released into a lower priced segment (25 percent cheaper at launch).
  • More modern: Reflects 3 years and 6 months of technical progress since the 10D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the Digilux 3 is the clear winner of the contest (10 : 4 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.

10D 04:10 Digilux 3

How about other alternatives? Do the specifications of the Canon 10D and the Leica Digilux 3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 10D or the Digilux 3. 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 adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

The above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
