Panasonic G5 versus Panasonic GX7

The Panasonic Lumix DMC-G5 and the Panasonic Lumix DMC-GX7 are two digital cameras that were revealed to the public, respectively, in July 2012 and August 2013. Both the G5 and the GX7 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G5 has a resolution of 15.9 megapixel, whereas the GX7 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 G5 vs Panasonic GX7

An illustration of the physical size and weight of the Panasonic G5 and the Panasonic GX7 is provided in the side-by-side display below. The two cameras are presented according to their relative size. 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 side – the G5 – represents the basis for the calculations 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 GX7 is notably smaller (12 percent) than the Panasonic G5. However, the GX7 is slightly heavier (2 percent) than the G5. In this context, it is worth noting that neither the G5 nor the GX7 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 G5 gets 320 shots out of its DMW-BLC12 battery, while the GX7 can take 350 images on a single charge of its DMW-BLG10 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G5 was launched at a markedly lower price (by 40 percent) than the GX7, 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 G5 vs Panasonic GX7

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 are more costly to manufacture and tend to 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 G5 and Panasonic GX7 sensor measures

While the two cameras under review share the same sensor size, the G5 offers a slightly higher resolution of 15.9 megapixel, compared with 15.8 MP of the GX7. This megapixel advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the 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 GX7). Moreover, it should be noted that the GX7 is a somewhat more recent model (by 1 year) than the G5, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

G5 versus GX7 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Panasonic G5 vs Panasonic GX7

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the GX7 offers a substantially higher resolution than the one in the G5 (2760k vs 1440k dots). The adjacent table lists some of the other core features of the Panasonic G5 and Panasonic GX7 along with similar information for a selection of comparators.

One feature that differentiates the GX7 and the G5 is in-body image stabilization (IBIS). The GX7 reduces the risk of handshake-induced blur with all attached lenses, while the G5 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX7 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the G5 and the GX7 have been discontinued, but can regularly be found used on eBay. The G5 was replaced by the Panasonic G6, while the GX7 was followed by the Panasonic GX85.

Review summary: Panasonic G5 vs Panasonic GX7

So how do things add up? Is there a clear favorite between the Panasonic G5 and the Panasonic GX7? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Panasonic Lumix DMC-G5:

  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in July 2012).


Advantages of the Panasonic Lumix DMC-GX7:

  • More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 1440k dots).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (123x71mm vs 120x83mm) and will fit more readily into a bag.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (1 year) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the GX7 emerges as the winner of the match-up (7 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

G5 04:07 GX7

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G5 or the GX7. 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
