Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D Mark III and the Leica D-LUX 6? 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 1D Mark III and the Leica D-LUX 6 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

The D-LUX 6 can be obtained in three different colors (black, silver, white), while the 1D Mark III 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 D-LUX 6 is considerably smaller (69 percent) than the Canon 1D Mark III. It is worth mentioning in this context that the 1D Mark III is splash and dust resistant, while the D-LUX 6 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 6 has a lens built in, whereas the 1D Mark III 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 1D Mark III and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 1D Mark III gets 2200 shots out of its Canon LP-E4 battery, while the D-LUX 6 can take 330 images on a single charge of its Leica BP-DC10 power pack. As can be seen in the images above, the 1D Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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.

Any camera decision will obviously take relative prices into account. 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 D-LUX 6 was launched at a lower price than the 1D Mark III, despite having a lens built in. 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. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 1D Mark III features an APS-H sensor and the Leica D-LUX 6 a 1/1.7-inch sensor. The sensor area in the D-LUX 6 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 4.65. The sensor in the 1D Mark III has a native 3:2 aspect ratio, while the one in the D-LUX 6 offers a 4:3 aspect. The D-LUX 6 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

With 10.1MP, the 1D Mark III offers a slightly higher resolution than the D-LUX 6 (10MP), but the 1D Mark III nevertheless has larger individual pixels (pixel pitch of 7.21μm versus 2.05μm for the D-LUX 6) due to its larger sensor. However, the D-LUX 6 is a much more recent model (by 5 years and 6 months) than the 1D Mark III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Canon EOS-1D Mark III has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 50-6400. The corresponding ISO settings for the Leica D-LUX 6 are ISO 80 to ISO 6400, with the possibility to increase the ISO range to 80-12800.

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 are not only capable of taking still images, but can also record movies. The D-LUX 6 indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the D-LUX 6 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1D Mark III has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the D-LUX 6 relies on live view and the rear LCD for framing. That said, the D-LUX 6 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The table below summarizes some of the other core capabilities of the Canon 1D Mark III and Leica D-LUX 6 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 1D Mark III, but is missing on the D-LUX 6 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 Leica D-LUX 6 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the D-LUX 6 uses SDXC cards. The 1D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the D-LUX 6 only has one slot.

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-1D Mark III and Leica D-LUX 6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 1D Mark III (unlike the D-LUX 6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D Mark III and the D-LUX 6 have been discontinued, but can regularly be found used on ebay. The 1D Mark III was replaced by the Canon 1D Mark IV, while the D-LUX 6 was followed by the Leica D-LUX Typ 109. Further information on the features and operation of the 1D Mark III and D-LUX 6 can be found, respectively, in the Canon 1D Mark III Manual (free pdf) or the online Leica D-LUX 6 Manual.

Review summary

So how do things add up? Is the Canon 1D Mark III better than the Leica D-LUX 6 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS-1D Mark III:

• 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.
• 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 (1/8000s vs 1/4000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (2200 versus 330) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in February 2007).

Advantages of the Leica D-LUX 6:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the 1D Mark III requires a separate lens.
• More compact: Is smaller (111x68mm vs 156x157mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 1D Mark III).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 5 years and 6 months of technical progress since the 1D Mark III launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 1D Mark III emerges as the winner of the contest (14 : 12 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 1D Mark III and the Leica D-LUX 6 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 1D Mark III and the D-LUX 6 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age.

It should also be noted that some of the review sites have over time altered the way they render their verdicts.
