Going beyond this snapshot of core features and characteristics, what are the differences between the Leica C-LUX 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

An illustration of the physical size and weight of the Leica C-LUX and the Panasonic G2 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 size dimensions are rounded to the nearest millimeter.

The C-LUX can be obtained in two different colors (gold, blue), while the G2 is available in three color-versions (black, blue, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G2 is notably larger (38 percent) than the Leica C-LUX. In this context, it is worth noting that neither the C-LUX nor the G2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the C-LUX 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.

The power pack in the C-LUX can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

The price is, of course, an important factor in any camera decision. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica C-LUX features an one-inch sensor and the Panasonic G2 a Four Thirds sensor. The sensor area in the G2 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the C-LUX has a native 3:2 aspect ratio, while the one in the G2 offers a 4:3 aspect.

Despite having a smaller sensor, the Leica C-LUX offers a higher resolution of 20 megapixels, compared with 12 MP of the Panasonic G2. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.33μm for the G2). However, it should be noted that the C-LUX is much more recent (by 8 years and 3 months) than the G2, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Leica C-LUX implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the C-LUX for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Panasonic G2 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 C-LUX has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Panasonic Lumix DMC-G2 are ISO 100 to ISO 6400 (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.

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 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the C-LUX provides a higher video resolution than the G2. It can shoot video footage at 4K/30p, while the Panasonic is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the C-LUX offers a substantially higher resolution than the one in the G2 (2330k vs 1440k dots). The table below summarizes some of the other core capabilities of the Leica C-LUX and Panasonic G2 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the C-LUX is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Leica C-LUX 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.

Concerning the storage of imaging data, both the C-LUX and the G2 write their files to SDXC cards. The C-LUX supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G2 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 C-LUX and Panasonic Lumix DMC-G2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the C-LUX offers wifi support, while the G2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the C-LUX and the G2 have been discontinued, but can regularly be found used on ebay. The G2 was replaced by the Panasonic G3, while the C-LUX does not have a direct successor. Further information on the features and operation of the C-LUX and G2 can be found, respectively, in the Leica C-LUX Manual (free pdf) or the online Panasonic G2 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Leica C-LUX and the Panasonic G2? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Leica C-LUX:

• More detail: Offers more megapixels (20 vs 12MP) with a 32% higher linear resolution.
• Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (2330k vs 1440k dots).
• More detailed LCD: Has a higher resolution rear screen (1240k vs 460k dots).
• Faster burst: Shoots at higher frequency (10 vs 2.6 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has a lens built-in, whereas the G2 requires a separate lens.
• More compact: Is smaller (113x67mm 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).
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Reflects 8 years and 3 months of technical progress since the G2 launch.

Reasons to prefer the Panasonic Lumix DMC-G2:

• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.53x).
• 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 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.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in March 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the C-LUX is the clear winner of the match-up (16 : 7 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 C-LUX and the Panasonic G2 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the C-LUX or the G2. 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 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.

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

The review scores listed above should be treated with care, 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
