Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 5 and the Sony Alpha NEX-3N? 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 physical size and weight of the Leica D-LUX 5 and the Sony NEX-3N are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

The NEX-3N can be obtained in two different colors (black, white), while the D-LUX 5 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 NEX-3N is somewhat smaller (5 percent) than the Leica D-LUX 5. In this context, it is worth noting that neither the D-LUX 5 nor the NEX-3N are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 5 has a lens built in, whereas the NEX-3N 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 NEX-3N and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the D-LUX 5 gets 400 shots out of its Leica BP-DC10 battery, while the NEX-3N can take 480 images on a single charge of its Sony NP-FW50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 5 features a 1/1.7-inch sensor and the Sony NEX-3N an APS-C sensor. The sensor area in the NEX-3N is 693 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.4 and 1.5. The sensor in the D-LUX 5 has a native 4:3 aspect ratio, while the one in the NEX-3N offers a 3:2 aspect. The D-LUX 5 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 16MP, the NEX-3N offers a higher resolution than the D-LUX 5 (10MP), but the NEX-3N nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 2.14μm for the D-LUX 5) due to its larger sensor. Moreover, the NEX-3N is a much more recent model (by 2 years and 5 months) than the D-LUX 5, and its sensor will 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 NEX-3N implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-3N for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.6 x 27.6 cm. The corresponding values for the Leica D-LUX 5 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 5 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Sony Alpha NEX-3N are ISO 200 to ISO 16000 (no boost).

In terms of underlying technology, the D-LUX 5 is build around a CCD sensor, while the NEX-3N uses a CMOS imager. 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 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the NEX-3N provides a better video resolution than the D-LUX 5. It can shoot movie footage at 1080/60i, while the Leica is limited to 720/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D-LUX 5 and the NEX-3N 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 EVF1 for the D-LUX 5 and the FDA-SV1 for the NEX-3N – are available as accessories. The following table reports on some other key feature differences and similarities of the Leica D-LUX 5, the Sony NEX-3N, and comparable cameras.

It is notable that the D-LUX 5 has a hotshoe, while the NEX-3N does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the D-LUX 5 and the NEX-3N have been discontinued, but can regularly be found used on ebay. The D-LUX 5 was replaced by the Leica D-LUX 6, while the NEX-3N was followed by the Sony A5000. Further information on the features and operation of the D-LUX 5 and NEX-3N can be found, respectively, in the Leica D-LUX 5 Manual (free pdf) or the online Sony NEX-3N Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Leica D-LUX 5 and the Sony NEX-3N? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Leica D-LUX 5:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Ready to shoot: Has a lens built-in, whereas the NEX-3N requires a separate lens.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been available for much longer (launched in September 2010).

Arguments in favor of the Sony Alpha NEX-3N:

• More detail: Has more megapixels (16 vs 10MP), which boosts linear resolution by 29%.
• 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 video: Provides higher definition movie capture (1080/60i vs 720/60p).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (4 vs 2.5 flaps/sec) to capture the decisive moment.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (480 versus 400) out of a single battery charge.
• More modern: Reflects 2 years and 5 months of technical progress since the D-LUX 5 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the NEX-3N is the clear winner of the contest (12 : 6 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 5 and the Sony NEX-3N 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D-LUX 5 or the NEX-3N. 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 hands-on reviews by experts 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
