Panasonic GH2 vs GX1
The Panasonic Lumix DMC-GH2 and the Panasonic Lumix DMC-GX1 are two enthusiast cameras that were officially introduced, respectively, in September 2010 and November 2011. Both the GH2 and the GX1 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GH2 has a resolution of 15.9 megapixels, whereas the GX1 provides 15.8 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-GH2 and the Panasonic Lumix DMC-GX1? 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 GH2 and the Panasonic GX1 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 size dimensions are rounded to the nearest millimeter.
The GH2 can be obtained in two different colors (black, silver), while the GX1 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX1 is notably smaller (29 percent) than the Panasonic GH2. Moreover, the GX1 is markedly lighter (28 percent) than the GH2. In this context, it is worth noting that neither the GH2 nor the GX1 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GX1 was launched at a somewhat lower price (by 22 percent) than the GH2, which makes it more attractive for photographers on a tight budget. 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 size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 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 slightly higher resolution of 15.9 megapixels, compared with 15.8 MP of the GX1. This megapixels advantage translates into a 0.3 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 3.77μm for the GX1). Moreover, it should be noted that the GX1 is a somewhat more recent model (by 1 year and 1 month) than the GH2, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.
The Panasonic Lumix DMC-GH2 has a native sensitivity range from ISO 160 to ISO 12800. The Panasonic Lumix DMC-GX1 offers exactly the same ISO settings.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 GX1 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.4 bits higher color depth, 0.7 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX1 provides a faster frame rate than the GH2. It can shoot movie footage at 1080/60p, while the GH2 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety 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 GX1 relies on live view and the rear LCD for framing. That said, the GX1 can be equipped with an optional viewfinder – the DMW-LVF2. The adjacent table lists some of the other core features of the Panasonic GH2 and Panasonic GX1 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX1 has a touchscreen, while the GH2 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The GH2 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the GX1 does not have a selfie-screen.
Concerning the storage of imaging data, both the GH2 and the GX1 write their files to SDXC cards. The GX1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GH2 cannot take advantage of Ultra High Speed SD 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-GH2 and Panasonic Lumix DMC-GX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH2 has a microphone port, which is missing on the GX1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the GH2 and the GX1 have been discontinued, but can regularly be found used on eBay. The GH2 was replaced by the Panasonic GH3, while the GX1 was followed by the Panasonic GX7. 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 how do things add up? Is there a clear favorite between the Panasonic GH2 and the Panasonic GX1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Panasonic Lumix DMC-GH2:
- Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- 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.
- More heavily discounted: Has been on the market for longer (launched in September 2010).
Advantages of the Panasonic Lumix DMC-GX1:
- Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (4.2 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (116x68mm vs 124x90mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 124g or 28 percent) and is thus easier to take along.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was released into a lower priced segment (22 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 1 month) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the GX1 comes out slightly ahead of the GH2 (8 : 7 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 Panasonic GH2 and the Panasonic GX1 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the GH2 or the GX1 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
