Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 6 and the Sony Alpha SLT-A77 II? 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 Leica D-LUX 6 and the Sony A77 II is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

The D-LUX 6 can be obtained in three different colors (black, silver, white), while the A77 II 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 Sony A77 II is considerably larger (97 percent) than the Leica D-LUX 6. It is noteworthy in this context that the A77 II is splash and dust-proof, 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 A77 II 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 D-LUX 6 gets 330 shots out of its Leica BP-DC10 battery, while the A77 II can take 480 images on a single charge of its Sony NP-FM500H power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 A77 II, despite having a lens built in. 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 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 Leica D-LUX 6 features a 1/1.7-inch sensor and the Sony A77 II an APS-C sensor. The sensor area in the A77 II is 774 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 1.5. The sensor in the D-LUX 6 has a native 4:3 aspect ratio, while the one in the A77 II offers a 3:2 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 A77 II offers a higher resolution than the D-LUX 6 (10MP), but the A77 II nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.05μm for the D-LUX 6) due to its larger sensor. Moreover, the A77 II is a somewhat more recent model (by 1 year and 7 months) than the D-LUX 6, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A77 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A77 II 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 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 Sony Alpha SLT-A77 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

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 can also record movies. 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

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A77 II has an electronic viewfinder (2359k dots), which can be very helpful 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 following table reports on some other key feature differences and similarities of the Leica D-LUX 6, the Sony A77 II, and comparable cameras.

One feature that is present on the A77 II, 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 D-LUX 6 writes its imaging data to SDXC cards, while the A77 II uses SDXC or Memory Stick PRO Duo cards. The A77 II 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 Sony Alpha SLT-A77 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A77 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D-LUX 6 does not provide wifi capability.

Studio photographers will appreciate that the Sony A77 II (unlike the D-LUX 6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D-LUX 6 and the A77 II 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 A77 II does not have a direct successor. Further information on the features and operation of the D-LUX 6 and A77 II can be found, respectively, in the Leica D-LUX 6 Manual (free pdf) or the online Sony A77 II Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Leica D-LUX 6 or the Sony A77 II – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Leica D-LUX 6:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with a built-in lens, while the A77 II requires a separate lens.
• More compact: Is smaller (111x68mm vs 143x104mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the A77 II).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in September 2012).

Reasons to prefer the Sony Alpha SLT-A77 II:

• More detail: Has more megapixels (24 vs 10MP), which boosts linear resolution by 58%.
• Better image quality: Is equipped with a larger and more technologically advanced 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 sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 920k dots).
• More flexible LCD: Has a full-flex screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (480 versus 330) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• 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.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Was introduced somewhat (1 year and 7 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the A77 II is the clear winner of the contest (20 : 8 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 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 Leica D-LUX 6 and the Sony A77 II place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings 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 says little about, for example, the shooting experience and imaging performance of the D-LUX 6 and the A77 II in practical situations. 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 why expert reviews are important. 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.

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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
