Going beyond this snapshot of core features and characteristics, what are the differences between the Leica V-LUX 3 and the Sony Alpha NEX-7? 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 V-LUX 3 and the Sony NEX-7. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-7 is notably smaller (20 percent) than the Leica V-LUX 3. In this context, it is worth noting that neither the V-LUX 3 nor the NEX-7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the V-LUX 3 has a lens built in, whereas the NEX-7 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-7 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the V-LUX 3 gets 410 shots out of its Leica BP-DC9 battery, while the NEX-7 can take 430 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. 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.

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 V-LUX 3 was launched at a lower price than the NEX-7, 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. 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. 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. 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 V-LUX 3 features a 1/2.3-inch sensor and the Sony NEX-7 an APS-C sensor. The sensor area in the NEX-7 is 1204 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the V-LUX 3 has a native 4:3 aspect ratio, while the one in the NEX-7 offers a 3:2 aspect.

With 24MP, the NEX-7 offers a higher resolution than the V-LUX 3 (12MP), but the NEX-7 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 1.53μm for the V-LUX 3) due to its larger sensor. However, the V-LUX 3 is a somewhat more recent model (by 3 months) than the NEX-7, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the V-LUX 3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 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 V-LUX 3 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Leica V-LUX 3 has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Sony Alpha NEX-7 are ISO 100 to ISO 16000 (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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the V-LUX 3 provides a higher frame rate than the NEX-7. It can shoot video footage at 1080/60p, while the Sony is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the NEX-7 offers a substantially higher resolution than the one in the V-LUX 3 (2359k vs 202k dots). The following table reports on some other key feature differences and similarities of the Leica V-LUX 3, the Sony NEX-7, and comparable cameras.

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 V-LUX 3 and Sony Alpha NEX-7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NEX-7 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The V-LUX 3 does not feature such a mic input.

Both the V-LUX 3 and the NEX-7 have been discontinued, but can regularly be found used on ebay. The V-LUX 3 was replaced by the Leica V-LUX 4, while the NEX-7 does not have a direct successor. Further information on the features and operation of the V-LUX 3 and NEX-7 can be found, respectively, in the Leica V-LUX 3 Manual (free pdf) or the online Sony NEX-7 Manual.

Review summary

So how do things add up? Is the Leica V-LUX 3 better than the Sony NEX-7 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Leica V-LUX 3:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• More flexible LCD: Has a swivel 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 burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the NEX-7 requires a separate lens.
• 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: Is somewhat more recent (announced 3 months after the NEX-7).

Reasons to prefer the Sony Alpha NEX-7:

• More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 202k dots).
• More detailed LCD: Has a higher resolution rear screen (921k vs 460k dots).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (120x67mm vs 124x81mm) and will fit more readily into a bag.
• More heavily discounted: Has been on the market for longer (launched in August 2011).

If the count of individual advantages (bullet points above) is taken as a guide, the NEX-7 emerges as the winner of the match-up (13 : 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 V-LUX 3 and the Sony NEX-7 place the cameras among the top in their class? Find out in the latest Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the V-LUX 3 and the NEX-7 in practical situations. 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 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
