Panasonic GX1 versus Panasonic G6

The Panasonic Lumix DMC-GX1 and the Panasonic Lumix DMC-G6 are two digital cameras that were officially introduced, respectively, in November 2011 and April 2013. Both the GX1 and the Lumix G6 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GX1 has a resolution of 15.8 megapixel, whereas the Lumix G6 provides 15.9 MP.

Body comparison

An illustration of the physical size and weight of the Panasonic GX1 and the Panasonic G6 is provided in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative 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 G6 is notably larger (31 percent) than the Panasonic GX1. Moreover, the Lumix G6 is markedly heavier (23 percent) than the GX1. In this context, it is worth noting that neither the GX1 nor the Lumix G6 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Lumix G6 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

The size of the imaging sensor is a crucial determinant 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 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.

Sensor size

While the two cameras under review share the same sensor size, the Lumix G6 offers a higher resolution of 15.9 megapixel, compared with 15.8 MP of the GX1. This megapixel advantage translates into a 0 percent gain in linear resolution. On the other hand, these sensor specs imply that the Lumix G6 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). However, it should be noted that the Lumix G6 is a somewhat more recent model (by 1 year and 5 months) than the GX1, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

Sensor resolution

For most 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. Of the two cameras under consideration, the Lumix G6 has a markedly higher DXO score than the GX1 (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.5 bits higher color depth, 0.9 EV in additional dynamic range, 0.1 stops of reduced 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 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, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Lumix G6 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 following table reports on some other key feature differences and similarities of the Panasonic GX1, the Panasonic G6, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the GX1 and the Lumix G6 have been discontinued, but can regularly be found used on ebay. The GX1 was replaced by the Panasonic GX7, while the Lumix G6 was followed by the Panasonic G7.

Summary

So how do things add up? Is the Panasonic GX1 better than the Panasonic G6 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Panasonic Lumix DMC-GX1:

  • More compact: Is smaller (116x68mm vs 122x85mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 72g or 18 percent) and hence easier to carry around.
  • More heavily discounted: Has been on the market for longer (launched in November 2011).

Reasons to prefer the Panasonic Lumix DMC-G6:

  • Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1036k vs 460k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (7 vs 4.2 flaps/sec) to capture the decisive moment.
  • More affordable: Was introduced into a lower priced category (37 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 5 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the Lumix G6 is the clear winner of the contest (8 : 3 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.

GX1 03:08 Lumix G6

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 GX1 or the Lumix G6 handle or 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 adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings are only valid when refering 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
