Panasonic GX1 versus Panasonic G2

The Panasonic Lumix DMC-GX1 and the Panasonic Lumix DMC-G2 are two digital cameras that were revealed to the public, respectively, in November 2011 and March 2010. Both the GX1 and the G2 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GX1 has a resolution of 15.8 megapixel, whereas the G2 provides 12 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 GX1 vs Panasonic G2

An illustration of the physical size and weight of the Panasonic GX1 and the Panasonic G2 is provided in the side-by-side display below. 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. 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 GX1 – 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 G2 is notably larger (32 percent) than the Panasonic GX1. Moreover, the G2 is substantially heavier (35 percent) than the GX1. In this context, it is worth noting that neither the GX1 nor the G2 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 GX1 gets 320 shots out of its DMW-BLD10 battery, while the G2 can take 360 images on a single charge of its DMW-BLB13 power pack.

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 GX1 vs Panasonic G2

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 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. 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 more expensive and lead to bigger and heavier cameras 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 GX1 and Panasonic G2 sensor measures

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). In this context, it should be noted, however, 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.

GX1 versus G2 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GX1 provides a higher video resolution than the G2. It can shoot video footage at 1080/60p, while the G2 is limited to 720/30p.

 

Feature comparison: Panasonic GX1 vs Panasonic G2

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 adjacent table lists some of the other core features of the Panasonic GX1 and Panasonic G2 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the GX1 and the G2 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.

Review summary: Panasonic GX1 vs Panasonic G2

So what is the bottom line? Which of the two cameras – the Panasonic GX1 or the Panasonic G2 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Panasonic Lumix DMC-GX1:

  • More detail: Offers more megapixels (15.8 vs 12MP) with a 15% higher linear resolution.
  • Better low-light sensitivity: Requires less light for good images (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 thus needs less room in the bag.
  • Less heavy: Is lighter (by 110g or 26 percent) and hence easier to carry around.
  • More modern: Is somewhat more recent (announced 1 year and 8 months after the G2).


Arguments in favor of 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: Gets more shots (360 versus 320) out of 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).

If the count of individual advantages (bullet points above) is taken as a guide, the GX1 emerges as the winner of the contest (7 : 5 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.

GX1 07:05 G2

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 GX1 or the G2 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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.
