Panasonic G5 versus Panasonic GX1

The Panasonic Lumix DMC-G5 and the Panasonic Lumix DMC-GX1 are two digital cameras that were officially introduced, respectively, in July 2012 and November 2011. Both the Lumix G5 and the GX1 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Lumix G5 has a resolution of 15.9 megapixel, whereas the GX1 provides 15.8 MP.

Body comparison

An illustration of the physical size and weight of the Panasonic G5 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 Lumix G5 – 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 (21 percent) than the Panasonic G5. Moreover, the GX1 is markedly lighter (20 percent) than the Lumix G5. In this context, it is worth noting that neither the Lumix G5 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Lumix G5 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 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. 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.

Sensor size

While the two cameras under review share the same sensor size, the Lumix G5 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 G5 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). In this context, it should be noted, however, that the Lumix G5 is a somewhat more recent model (by 8 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.

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the Lumix G5 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 G5, the Panasonic GX1, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the Lumix G5 and the GX1 have been discontinued, but can regularly be found used on ebay. The GX1 was replaced by the Panasonic GX7, while the Lumix G5 was followed by the Panasonic G6.

Summary

So what is the bottom line? Which of the two cameras – the Panasonic G5 or the Panasonic GX1 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Panasonic Lumix DMC-G5:

  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More detailed LCD: Has a higher resolution rear screen (920k 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 (6 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: Is somewhat more recent (announced 8 months after the GX1).

Reasons to prefer the Panasonic Lumix DMC-GX1:

  • More compact: Is smaller (116x68mm vs 120x83mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 78g or 20 percent) and is thus easier to take along.
  • More heavily discounted: Has been on the market for longer (launched in November 2011).

If the count of individual advantages (bullet points above) is taken as a guide, the Lumix G5 emerges as the winner of the contest (6 : 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.

Lumix G5 06:03 GX1

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the Lumix G5 or the GX1. 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 hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
