Going beyond this snapshot of core features and characteristics, what are the differences between the Leica X2 and the Panasonic Lumix DMC-GH2? 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 X2 and the Panasonic GH2 is provided 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.

Both cameras are available in two different colors (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH2 is notably larger (30 percent) than the Leica X2. In this context, it is worth noting that neither the X2 nor the GH2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X2 has a lens built in, whereas the GH2 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 GH2 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the X2 gets 450 shots out of its Leica BP-DC8 battery, while the GH2 can take 330 images on a single charge of its Panasonic DMW-BLC12 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica X2 features an APS-C sensor and the Panasonic GH2 a Four Thirds sensor. The sensor area in the GH2 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X2 has a native 3:2 aspect ratio, while the one in the GH2 offers a 4:3 aspect.

With 16.1MP, the X2 offers a slightly higher resolution than the GH2 (15.9MP), but the X2 nevertheless has larger individual pixels (pixel pitch of 4.79μm versus 3.76μm for the GH2) due to its larger sensor. Moreover, the X2 is a somewhat more recent model (by 1 year and 7 months) than the GH2, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Leica X2 has a native sensitivity range from ISO 100 to ISO 12500. The corresponding ISO settings for the Panasonic Lumix DMC-GH2 are ISO 160 to ISO 12800 (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.

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 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 GH2 indeed provides for movie recording, while the X2 does not. The highest resolution format that the GH2 can use is 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH2 has an electronic viewfinder (1534k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X2 relies on live view and the rear LCD for framing. That said, the X2 can be equipped with an optional viewfinder – the EVF 2. The following table reports on some other key feature differences and similarities of the Leica X2, the Panasonic GH2, and comparable cameras.

Both the X2 and the GH2 have been discontinued, but can regularly be found used on ebay. The GH2 was replaced by the Panasonic GH3, while the X2 does not have a direct successor. Further information on the features and operation of the X2 and GH2 can be found, respectively, in the Leica X2 Manual (free pdf) or the online Panasonic GH2 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Leica X2 and the Panasonic GH2? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Leica X2:

• Better image quality: Features a larger and more technologically advanced imaging 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.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Has a lens built-in, whereas the GH2 requires a separate lens.
• More compact: Is smaller (124x69mm vs 124x90mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the GH2).
• Longer lasting: Can take more shots (450 versus 330) on a single battery charge.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Is somewhat more recent (announced 1 year and 7 months after the GH2).

Reasons to prefer the Panasonic Lumix DMC-GH2:

• Broader imaging potential: Can capture not only stills but also 1080/60i video.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• 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.
• More heavily discounted: Has been on the market for longer (launched in September 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the X2 emerges as the winner of the contest (11 : 9 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 X2 and the Panasonic GH2 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 says little about, for example, the shooting experience and imaging performance of the X2 and the GH2 in practical situations. 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 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.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
