Body comparison

An illustration of the physical size and weight of the Panasonic GX7 and the Sony A7R 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.

The GX7 can be obtained in two different colors (black, silver), while the A7R is only available in black.

Size Panasonic GX7 vs Sony A7R
Compare GX7 versus A7R top
Comparison GX7 or A7R rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R is notably larger (37 percent) than the Panasonic GX7. Moreover, the A7R is markedly heavier (16 percent) than the GX7. It is noteworthy in this context that the A7R is splash and dust-proof, while the GX7 does not feature any corresponding weather-sealing.

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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (GX7) and the Sony FE Lens Catalog (A7R). 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 GX7 gets 350 shots out of its Panasonic DMW-BLG10 battery, while the A7R can take 340 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A7R can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 GX7 was launched at a markedly lower price (by 57 percent) than the A7R, 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 sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GX7 features a Four Thirds sensor and the Sony A7R a full frame sensor. The sensor area in the A7R is 283 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the GX7 has a native 4:3 aspect ratio, while the one in the A7R offers a 3:2 aspect.

Panasonic GX7 and Sony A7R sensor measures

With 36.2MP, the A7R offers a higher resolution than the GX7 (15.8MP), but the A7R nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.77μm for the GX7) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the A7R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A7R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Panasonic GX7 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.

The Panasonic Lumix DMC-GX7 has a native sensitivity range from ISO 125 to ISO 25600. The corresponding ISO settings for the Sony Alpha A7R are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

GX7 versus A7R MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the A7R offers substantially better image quality than the GX7 (overall score 25 points higher). The advantage is based on 3 bits higher color depth, 1.9 EV in additional dynamic range, and 1.9 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The GX7 has one, while the A7R does not. While the built-in flash of the GX7 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the GX7 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic GX7 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The GX7 writes its imaging data to SDXC cards, while the A7R uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the A7R has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The GX7 lacks such a headphone port.

Both the GX7 and the A7R have been discontinued, but can regularly be found used on ebay. The GX7 was replaced by the Panasonic GX85, while the A7R was followed by the Sony A7R II. Further information on the features and operation of the GX7 and A7R can be found, respectively, in the Panasonic GX7 Manual (free pdf) or the online Sony A7R Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Panasonic GX7 or the Sony A7R – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Panasonic Lumix DMC-GX7:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2760k vs 2400k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (123x71mm vs 127x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 63g or 14 percent) and hence easier to carry around.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).

ilogo

Arguments in favor of the Sony Alpha A7R:

  • More detail: Has more megapixels (36.2 vs 15.8MP), which boosts linear resolution by 54%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (25 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.70x).
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R comes out slightly ahead of the GX7 (12 : 11 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GX7 11:12 A7R

How about other alternatives? Do the specifications of the Panasonic GX7 and the Sony A7R place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

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 shooting experience and imaging performance when actually working with the GX7 or the A7R. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
