Panasonic G2 versus Panasonic GX1
The Panasonic Lumix DMC-G2 and the Panasonic Lumix DMC-GX1 are two digital cameras that were officially introduced, 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 megapixel, whereas the GX1 provides 15.8 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 GX1
An illustration of the physical size and weight of the Panasonic G2 and the Panasonic GX1 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage 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 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 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also 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 G2 was launched at a markedly lower price (by 37 percent) than the GX1, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Panasonic G2 vs Panasonic GX1
The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 GX1 offers a higher resolution of 15.8 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 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 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.
Feature comparison: Panasonic G2 vs Panasonic GX1
Beyond body and sensor, cameras can and do differ across a range 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. The table below summarizes some of the other core capabilities of the Panasonic G2 and Panasonic GX1 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Review summary: Panasonic G2 vs Panasonic GX1
So what is the bottom line? Which of the two cameras – the Panasonic G2 or the Panasonic GX1 – has the upper hand? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Panasonic Lumix DMC-G2:
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Longer lasting: Can take more shots (360 versus 320) on a single battery charge.
- More affordable: Was introduced into a lower priced category (37 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in March 2010).
Advantages 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.
- More modern: Was introduced somewhat (1 year and 8 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the GX1 emerges as the winner of the match-up (7 : 5 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G2 or the GX1 handle or perform in practice. 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 why expert reviews are important. 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 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
