Panasonic GH2 versus Panasonic G2

The Panasonic Lumix DMC-GH2 and the Panasonic Lumix DMC-G2 are two digital cameras that were announced, respectively, in September 2010 and March 2010. Both the GH2 and the G2 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GH2 has a resolution of 15.9 megapixel, whereas the G2 provides 12 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Panasonic GH2 vs Panasonic G2

The side-by-side display below illustrates the physical size and weight of the Panasonic GH2 and the Panasonic G2. 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the GH2 – represents 100 percent across all the size and weight measures).

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 smaller (7 percent) than the Panasonic GH2. Moreover, the G2 is slightly lighter (3 percent) than the GH2. In this context, it is worth noting that neither the GH2 nor the G2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the GH2 gets 330 shots out of its DMW-BLC12 battery, while the G2 can take 360 images on a single charge of its DMW-BLB13 power pack.

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

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G2 was launched at a markedly lower price (by 60 percent) than the GH2, which puts it into a different market segment. 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: Panasonic GH2 vs Panasonic G2

The size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Panasonic GH2 and Panasonic G2 sensor measures

While the two cameras under review share the same sensor size, the GH2 offers a higher resolution of 15.9 megapixel, compared with 12 MP of the G2. This megapixel advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the GH2 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.33μm for the G2). In this context, it should be noted, however, that the GH2 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 at least partly compensate for the smaller pixel size.

GH2 versus G2 MP

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"). Of the two cameras under review, the GH2 has a notably higher overall DXO score than the G2 (overall score 7 points higher), which gives it an advantage in terms of imaging quality. 1 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GH2 provides a higher video resolution than the G2. It can shoot video footage at 1080/60i, while the G2 is limited to 720/30p.

 

Feature comparison: Panasonic GH2 vs Panasonic G2

Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the GH2 offers a slightly higher resolution than the one in the G2 (1534k vs 1440k dots). The adjacent table lists some of the other core features of the Panasonic GH2 and Panasonic G2 along with similar information for a selection of comparators.

Review summary: Panasonic GH2 vs Panasonic G2

So how do things add up? Is there a clear favorite between the Panasonic GH2 and the Panasonic G2? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Panasonic Lumix DMC-GH2:

  • More detail: Offers more megapixels (15.9 vs 12MP) with a 15% higher linear resolution.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
  • Faster burst: Shoots at higher frequency (3 vs 2.6 flaps/sec) to capture the decisive moment.
  • More modern: Is somewhat more recent (announced 6 months after the G2).


Arguments in favor of the Panasonic Lumix DMC-G2:

  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).

If the number of relative strengths (bullet points above) is taken as a guide, the GH2 is the clear winner of the match-up (7 : 3 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.

GH2 07:03 G2

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GH2 and the G2 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
