Panasonic GH1 vs GH2
The Panasonic Lumix DMC-GH1 and the Panasonic Lumix DMC-GH2 are two enthusiast cameras that were announced, respectively, in March 2009 and September 2010. Both the GH1 and the GH2 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GH1 has a resolution of 12 megapixels, whereas the GH2 provides 15.9 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GH1 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.
The physical size and weight of the Panasonic GH1 and the Panasonic GH2 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 GH1 can be obtained in two different colors (black, red), while the GH2 is also available in two color-versions, but different ones (black, silver).
In this particular case, the Panasonic GH1 and the Panasonic GH2 have exactly the same width and height, and, thus, have identically-sized bodies. However, the GH2 is markedly heavier (15 percent) than the GH1. In this context, it is worth noting that neither the GH1 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 compare the optics available 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 two cameras under review were launched at the same price and fall into the same 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 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.
While the two cameras under review share the same sensor size, the GH2 offers a higher resolution of 15.9 megapixels, compared with 12 MP of the GH1. This megapixels 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 GH1). However, it should be noted that the GH2 is a somewhat more recent model (by 1 year and 6 months) than the GH1, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The resolution advantage of the Panasonic GH2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GH2 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Panasonic GH1 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 Panasonic Lumix DMC-GH1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DMC-GH2 are ISO 160 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the GH1 has a notably higher overall DXO score than the GH2 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.3 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GH2 provides a faster frame rate than the GH1. It can shoot movie footage at 1080/60i, while the GH1 is limited to 1080/24p.
Apart from body and sensor, cameras can and do differ across a variety 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 GH1 (1534k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Panasonic GH1, the Panasonic GH2, and comparable cameras.

The GH1 writes its imaging data to SDHC cards, while the GH2 uses SDXC cards.
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 Panasonic Lumix DMC-GH1 and Panasonic Lumix DMC-GH2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GH1 and the GH2 have been discontinued, but can regularly be found used on eBay. The GH1 was replaced by the Panasonic GH2, while the GH2 was followed by the Panasonic GH3. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.
So what conclusions can be drawn? Which of the two cameras – the Panasonic GH1 or the Panasonic GH2 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Panasonic Lumix DMC-GH1:
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- Less heavy: Is lighter (by 57g or 13 percent) and hence easier to carry around.
- More heavily discounted: Has been on the market for longer (launched in March 2009).
Reasons to prefer the Panasonic Lumix DMC-GH2:
- More detail: Has more megapixels (15.9 vs 12MP), which boosts linear resolution by 15%.
- Better video: Provides higher movie framerates (1080/60i versus 1080/24p).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.70x).
- More modern: Was introduced somewhat (1 year and 6 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the GH2 comes out slightly ahead of the GH1 (4 : 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. 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 Panasonic GH1 and the Panasonic GH2 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 GH1 or the GH2 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
