Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 6 and the Panasonic Lumix DMC-GX1? 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 Leica D-LUX 6 and the Panasonic GX1. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The D-LUX 6 can be obtained in three different colors (black, silver, white), while the GX1 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 Panasonic GX1 is somewhat larger (5 percent) than the Leica D-LUX 6. In this context, it is worth noting that neither the D-LUX 6 nor the GX1 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 GX1 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 GX1 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the D-LUX 6 gets 330 shots out of its Leica BP-DC10 battery, while the GX1 can take 320 images on a single charge of its Panasonic DMW-BLD10 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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. 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.

Of the two cameras under consideration, the Leica D-LUX 6 features a 1/1.7-inch sensor and the Panasonic GX1 a Four Thirds sensor. The sensor area in the GX1 is 436 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. 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 15.8MP, the GX1 offers a higher resolution than the D-LUX 6 (10MP), but the GX1 nevertheless has larger individual pixels (pixel pitch of 3.77μm versus 2.05μm for the D-LUX 6) due to its larger sensor. However, the D-LUX 6 is a somewhat more recent model (by 10 months) than the GX1, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Panasonic GX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX1 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 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 Leica D-LUX 6 has a native sensitivity range from ISO 80 to ISO 6400, which can be extended to ISO 80-12800. The corresponding ISO settings for the Panasonic Lumix DMC-GX1 are ISO 160 to ISO 12800 (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.

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, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D-LUX 6 and the GX1 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 Visoflex (Typ 020) for the D-LUX 6 and the DMW-LVF2 for the GX1 – are available as accessories. The following table reports on some other key feature differences and similarities of the Leica D-LUX 6, the Panasonic GX1, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX1 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 D-LUX 6 and the GX1 write their files to SDXC cards. The GX1 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 Leica D-LUX 6 and Panasonic Lumix DMC-GX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D-LUX 6 and the GX1 have been discontinued, but can regularly be found used on ebay. The GX1 was replaced by the Panasonic GX7, while the D-LUX 6 was followed by the Leica D-LUX Typ 109. Further information on the features and operation of the D-LUX 6 and GX1 can be found, respectively, in the Leica D-LUX 6 Manual (free pdf) or the online Panasonic GX1 Manual.

Review summary

So how do things add up? Which of the two cameras – the Leica D-LUX 6 or the Panasonic GX1 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Leica D-LUX 6:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
• 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 a lens built-in, whereas the GX1 requires a separate lens.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the GX1).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Is somewhat more recent (announced 10 months after the GX1).

Arguments in favor of the Panasonic Lumix DMC-GX1:

• More detail: Has more megapixels (15.8 vs 10MP), which boosts linear resolution by 26%.
• 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.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More heavily discounted: Has been on the market for longer (launched in November 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (9 points each). 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 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 Leica D-LUX 6 and the Panasonic GX1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 D-LUX 6 or the GX1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
