Panasonic G2 vs GX1
The Panasonic Lumix DMC-G2 and the Panasonic Lumix DMC-GX1 are two digital cameras that were revealed to the public, respectively, in March 2010 and November 2011. Both the G2 and the GX1 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G2 has a resolution of 12 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-G2 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 G2 and the Panasonic GX1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
The G2 can be obtained in three different colors (black, blue, red), 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 (24 percent) than the Panasonic G2. Moreover, the GX1 is markedly lighter (26 percent) than the G2. In this context, it is worth noting that neither the G2 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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. The G2 was launched at a somewhat lower price (by 14 percent) than the GX1, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 GX1 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the G2. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.33μm for the G2). However, it should be noted that the GX1 is a somewhat more recent model (by 1 year and 8 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.
The resolution advantage of the Panasonic GX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX1 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Panasonic G2 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-G2 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DMC-GX1 are ISO 160 to ISO 12800 (no boost).
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. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GX1 provides a better video resolution than the G2. It can shoot movie footage at 1080/60p, while the G2 is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G2 has an electronic viewfinder (1440k 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 G2 and Panasonic GX1 along with similar information for a selection of comparators.
Concerning the storage of imaging data, both the G2 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 G2 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-G2 and Panasonic Lumix DMC-GX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G2 and the GX1 have been discontinued, but can regularly be found used on eBay. The G2 was replaced by the Panasonic G3, 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 what conclusions can be drawn? Is there a clear favorite between the Panasonic G2 and the Panasonic GX1? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Panasonic Lumix DMC-G2:
- 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.
- Longer lasting: Can take more shots (360 versus 320) on a single battery charge.
- More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in March 2010).
Arguments in favor of the Panasonic Lumix DMC-GX1:
- More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
- Faster burst: Shoots at higher frequency (4.2 vs 2.6 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (116x68mm vs 124x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 110g or 26 percent) and is thus easier to take along.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Was introduced somewhat (1 year and 8 months) more recently.
If the number of relative strengths (bullet points above) is taken as a guide, the GX1 emerges as the winner of the match-up (8 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 G2 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G2 or the GX1. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
