Panasonic G2 versus Panasonic GH2

The Panasonic Lumix DMC-G2 and the Panasonic Lumix DMC-GH2 are two digital cameras that were announced, respectively, in March 2010 and September 2010. Both the G2 and the GH2 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G2 has a resolution of 12 megapixel, whereas the GH2 provides 15.9 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 G2 vs Panasonic GH2

The side-by-side display below illustrates the physical size and weight of the Panasonic G2 and the Panasonic GH2. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 G2 – represents the basis or 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 GH2 is notably larger (7 percent) than the Panasonic G2. Moreover, the GH2 is slightly heavier (3 percent) than the G2. In this context, it is worth noting that neither the G2 nor the GH2 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 G2 gets 360 shots out of its DMW-BLB13 battery, while the GH2 can take 330 images on a single charge of its DMW-BLC12 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. 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 G2 vs Panasonic GH2

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 associated with larger, more expensive camera bodies 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 G2 and Panasonic GH2 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). However, it should be noted 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.

G2 versus GH2 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the GH2 has a markedly higher DXO score than the G2 (overall score 7 points higher), which will translate into better image 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 better video resolution than the G2. It can shoot movie footage at 1080/60i, while the G2 is limited to 720/30p.

 

Feature comparison: Panasonic G2 vs Panasonic GH2

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 GH2 offers a slightly higher resolution than the one in the G2 (1534k vs 1440k dots). The table below summarizes some of the other core capabilities of the Panasonic G2 and Panasonic GH2 in connection with corresponding information for a sample of similar cameras.

Review summary: Panasonic G2 vs Panasonic GH2

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


Reasons to prefer the Panasonic Lumix DMC-G2:

  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in March 2010).


Advantages of the Panasonic Lumix DMC-GH2:

  • More detail: Has more megapixels (15.9 vs 12MP), which boosts linear resolution by 15%.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Faster burst: Shoots at higher frequency (3 vs 2.6 flaps/sec) to capture the decisive moment.
  • More modern: Was introduced somewhat (6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the GH2 is the clear winner of the contest (8 : 3 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.

G2 03:08 GH2

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G2 or the GH2. 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. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
