Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M3 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

The side-by-side display below illustrates the physical size and weight of the Canon M3 and the Leica D-LUX 6. 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 width, height and depth dimensions are rounded to the nearest millimeter.

The M3 can be obtained in two different colors (black, white), while the D-LUX 6 is available in three color-versions (black, silver, white).

In this particular case, the Canon M3 and the Leica D-LUX 6 have exactly the same width and height, and, thus, have identically-sized bodies. In this context, it is worth noting that neither the M3 nor the D-LUX 6 are weather-sealed.

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 M3 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

Concerning battery life, the M3 gets 250 shots out of its Canon LP-E17 battery, while the D-LUX 6 can take 330 images on a single charge of its Leica BP-DC10 power pack.

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.

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. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon M3 features an APS-C sensor and the Leica D-LUX 6 a 1/1.7-inch sensor. The sensor area in the D-LUX 6 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.65. The sensor in the M3 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 24MP, the M3 offers a higher resolution than the D-LUX 6 (10MP), but the M3 nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 2.05μm for the D-LUX 6) due to its larger sensor. Moreover, the M3 is a much more recent model (by 2 years and 4 months) than the D-LUX 6, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon M3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Leica D-LUX 6 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 M3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS M3 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D-LUX 6 provides a faster frame rate than the M3. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The M3 and the D-LUX 6 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the EVF-DC1 for the M3 and the Visoflex (Typ 020) for the D-LUX 6 – are available as accessories. The following table reports on some other key feature differences and similarities of the Canon M3, the Leica D-LUX 6, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M3 has a touchscreen, while the D-LUX 6 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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.

Concerning the storage of imaging data, both the M3 and the D-LUX 6 write their files to SDXC cards. The M3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D-LUX 6 cannot take advantage of Ultra High Speed SD 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 M3 and Leica D-LUX 6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M3 has a microphone port, which is missing on the D-LUX 6. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the M3 and the D-LUX 6 have been discontinued, but can regularly be found used on ebay. The D-LUX 6 was replaced by the Leica D-LUX Typ 109, while the M3 was followed by the Canon M6. Further information on the features and operation of the M3 and D-LUX 6 can be found, respectively, in the Canon M3 Manual (free pdf) or the online Leica D-LUX 6 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon M3 or the Leica D-LUX 6 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS M3:

• More detail: Offers more megapixels (24 vs 10MP) with a 58% 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.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 2 years and 4 months of technical progress since the D-LUX 6 launch.

Arguments in favor of the Leica D-LUX 6:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Faster burst: Shoots at higher frequency (11 vs 4.2 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has an integrated lens, whereas the M3 necessitates an extra lens.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the M3).
• Longer lasting: Gets more shots (330 versus 250) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• 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 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the M3 is the clear winner of the match-up (16 : 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 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.

How about other alternatives? Do the specifications of the Canon M3 and the Leica D-LUX 6 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 M3 or the D-LUX 6 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 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
