Canon 550D vs Leica Digilux 3
The Canon EOS 550D (called Canon T2i in some regions) and the Leica Digilux 3 are two digital cameras that were announced, respectively, in February 2010 and September 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (550D) and a Four Thirds (Digilux 3) sensor. The Canon has a resolution of 17.9 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 550D 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.
The side-by-side display below illustrates the physical size and weight of the Canon 550D 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 width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 550D and the Leica Digilux 3 are of equal size. However, the Digilux 3 is markedly heavier (14 percent) than the 550D. In this context, it is worth noting that neither the 550D 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 (550D) and the Four Thirds Lens Catalog (Digilux 3).
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera decision will naturally be influenced heavily by the price. 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 550D was launched at a markedly lower price (by 53 percent) than the Digilux 3, 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.
The size of the sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 550D features an APS-C sensor and the Leica Digilux 3 a Four Thirds sensor. The sensor area in the Digilux 3 is 32 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 550D has a native 3:2 aspect ratio, while the one in the Digilux 3 offers a 4:3 aspect.
With 17.9MP, the 550D offers a higher resolution than the Digilux 3 (7.4MP), but the 550D has smaller individual pixels (pixel pitch of 4.31μm versus 5.51μm for the Digilux 3). However, the 550D is a much more recent model (by 3 years and 4 months) than the Digilux 3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 550D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 550D for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Leica Digilux 3 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.
The Canon EOS 550D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Leica Digilux 3 are ISO 100 to ISO 1600 (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 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The 550D indeed provides movie recording capabilities, while the Digilux 3 does not. The highest resolution format that the 550D can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 550D 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 550D has a higher magnification than the one of the Digilux 3 (0.54x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 550D, the Leica Digilux 3, and comparable cameras.

Both the 550D and the Digilux 3 have been discontinued, but can regularly be found used on ebay. The 550D was replaced by the Canon 600D, while the Digilux 3 does not have a direct successor. Further information on the features and operation of the 550D and Digilux 3 can be found, respectively, in the Canon 550D Manual (free pdf) or the online Leica Digilux 3 Manual.
So how do things add up? Is the Canon 550D better than the Leica Digilux 3 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 550D:
- More detail: Offers more megapixels (17.9 vs 7.4MP) with a 59% higher linear resolution.
- Better image quality: Features a larger and more technologically advanced imaging sensor.
- Richer colors: The sensor size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.47x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 207k dots).
- Faster burst: Shoots at higher frequency (3.7 vs 3 flaps/sec) to capture the decisive moment.
- Less heavy: Is lighter (by 76g or 13 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
- More modern: Reflects 3 years and 4 months of technical progress since the Digilux 3 launch.
Arguments in favor of the Leica Digilux 3:
- Longer lasting: Gets more shots (750 versus 440) out of a single battery charge.
- 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 2006).
If the count of relative strengths (bullet points above) is taken as a measure, the 550D is the clear winner of the match-up (13 : 3 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 550D 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 550D 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.
This is why hands-on reviews by experts 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
