Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 6 and the Nikon D90? 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 Nikon D90. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear 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 D90 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 Nikon D90 is considerably larger (80 percent) than the Leica D-LUX 6. In this context, it is worth noting that neither the D-LUX 6 nor the D90 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 D90 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 D90 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D-LUX 6 gets 330 shots out of its Leica BP-DC10 battery, while the D90 can take 850 images on a single charge of its Nikon EN-EL3e power pack.

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

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 D90, 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 imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 Leica D-LUX 6 features a 1/1.7-inch sensor and the Nikon D90 an APS-C sensor. The sensor area in the D90 is 788 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 D90 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 12.2MP, the D90 offers a higher resolution than the D-LUX 6 (10MP), but the D90 nevertheless has larger individual pixels (pixel pitch of 5.53μm 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 4 years) than the D90, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon D90 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D90 for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.5 x 36.2 cm, for very good quality (250 dpi) 17.2 x 11.4 inches or 43.6 x 28.9 cm, and for excellent quality (300 dpi) 14.3 x 9.5 inches or 36.3 x 24.1 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 Nikon D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.

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 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 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D-LUX 6 provides a higher video resolution than the D90. It can shoot video footage at 1080/60p, while the Nikon is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D90 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 Leica D-LUX 6 and Nikon D90 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D90, 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 D90 uses SDHC 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 Nikon D90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D-LUX 6 and the D90 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, 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 D90 can be found, respectively, in the Leica D-LUX 6 Manual (free pdf) or the online Nikon D90 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Leica D-LUX 6 and the Nikon D90? Which camera is better? 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.
• Better video: Provides higher definition movie capture (1080/60p vs 720/24p).
• Faster burst: Shoots at higher frequency (11 vs 4.5 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with a built-in lens, while the D90 requires a separate lens.
• More compact: Is smaller (111x68mm vs 132x103mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D90).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• 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 modern: Reflects 4 years of technical progress since the D90 launch.

Advantages of the Nikon D90:

• More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 13%.
• 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 a control panel on top to check shooting parameters.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (850 versus 330) out of a single battery charge.
• More heavily discounted: Has been around for much longer (launched in August 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the D-LUX 6 comes out slightly ahead of the D90 (11 : 10 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 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 Leica D-LUX 6 and the Nikon D90 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 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 D90 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 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
