Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 5 and the Panasonic Lumix DMC-G2? 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 Panasonic G2 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 dimensions are rounded to the nearest millimeter.

The G2 can be obtained in three different colors (black, blue, red), 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 Panasonic G2 is considerably larger (46 percent) than the Leica D-LUX 5. In this context, it is worth noting that neither the D-LUX 5 nor the G2 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 G2 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 G2 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the D-LUX 5 gets 400 shots out of its Leica BP-DC10 battery, while the G2 can take 360 images on a single charge of its Panasonic DMW-BLB13 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. 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 sensor inside a digital camera is one of the key determinants 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 Panasonic G2 a Four Thirds sensor. The sensor area in the G2 is 389 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.4 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. 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 12MP, the G2 offers a higher resolution than the D-LUX 5 (10MP), but the G2 nevertheless has larger individual pixels (pixel pitch of 4.33μm versus 2.14μm for the D-LUX 5) due to its larger sensor. However, the D-LUX 5 is a somewhat more recent model (by 6 months) than the G2, 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 G2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G2 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 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 Panasonic Lumix DMC-G2 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the D-LUX 5 is build around a CCD sensor, while the G2 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.

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 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 D-LUX 5 provides a higher frame rate than the G2. It can shoot video footage at 720/60p, while the Panasonic is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G2 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the D-LUX 5 relies on live view and the rear LCD for framing. That said, the D-LUX 5 can be equipped with an optional viewfinder – the EVF1. The adjacent table lists some of the other core features of the Leica D-LUX 5 and Panasonic G2 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G2 has a touchscreen, while the D-LUX 5 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Concerning the storage of imaging data, both the D-LUX 5 and the G2 write their files to SDXC 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 5 and Panasonic Lumix DMC-G2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D-LUX 5 and the G2 have been discontinued, but can regularly be found used on ebay. The G2 was replaced by the Panasonic G3, while the D-LUX 5 was followed by the Leica D-LUX 6. Further information on the features and operation of the D-LUX 5 and G2 can be found, respectively, in the Leica D-LUX 5 Manual (free pdf) or the online Panasonic G2 Manual.

Review summary

So what conclusions can be drawn? Is the Leica D-LUX 5 better than the Panasonic G2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Leica D-LUX 5:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Better video: Provides higher movie framerates (720/60p versus 720/30p).
• Ready to shoot: Has a lens built-in, whereas the G2 requires a separate lens.
• More compact: Is smaller (110x65mm vs 124x84mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the G2).
• Longer lasting: Can take more shots (400 versus 360) on a single battery charge.
• 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 6 months after the G2).

Arguments in favor of the Panasonic Lumix DMC-G2:

• More detail: Has more megapixels (12 vs 10MP), which boosts linear resolution by 10%.
• 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 electronic viewfinder for image composition and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More heavily discounted: Has been on the market for longer (launched in March 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the G2 emerges as the winner of the match-up (11 : 9 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 5 and the Panasonic G2 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 5 or the G2 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
