Panasonic GH3 vs Sony NEX-7

The Panasonic Lumix DMC-GH3 and the Sony Alpha NEX-7 are two enthusiast cameras that were announced, respectively, in September 2012 and August 2011. Both the GH3 and the NEX-7 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GH3) and an APS-C (NEX-7) sensor. The Panasonic has a resolution of 15.9 megapixels, whereas the Sony provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GH3 and the Sony Alpha NEX-7? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison: Panasonic GH3 vs Sony NEX-7

The physical size and weight of the Panasonic GH3 and the Sony NEX-7 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Panasonic GH3 vs Sony NEX-7
Compare GH3 versus NEX-7 top
Comparison GH3 or NEX-7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-7 is considerably smaller (35 percent) than the Panasonic GH3. Moreover, the NEX-7 is markedly lighter (27 percent) than the GH3. It is worth mentioning in this context that the GH3 is splash and dust resistant, while the NEX-7 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 (GH3) and the Sony E-Mount Lens Catalog (NEX-7). 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 GH3 gets 540 shots out of its DMW-BLF19 battery, while the NEX-7 can take 430 images on a single charge of its NP-FW50 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as 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 GH3 was somewhat cheaper (by 4 percent) than the NEX-7 at launch, but both cameras fall into the same price category. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

 

Sensor comparison: Panasonic GH3 vs Sony NEX-7

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. 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.

Of the two cameras under consideration, the Panasonic GH3 features a Four Thirds sensor and the Sony NEX-7 an APS-C sensor. The sensor area in the NEX-7 is 62 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GH3 has a native 4:3 aspect ratio, while the one in the NEX-7 offers a 3:2 aspect.

Panasonic GH3 and Sony NEX-7 sensor measures

With 24MP, the NEX-7 offers a higher resolution than the GH3 (15.9MP), but the NEX-7 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 3.76μm for the GH3) due to its larger sensor. However, the GH3 is a somewhat more recent model (by 1 year) than the NEX-7, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Panasonic GH3 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

The Panasonic Lumix DMC-GH3 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Sony Alpha NEX-7 are ISO 100 to ISO 16000 (no boost).

GH3 versus NEX-7 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 NEX-7 has a markedly higher DXO score than the GH3 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.4 bits higher color depth, 1 EV in additional dynamic range, and 0.3 stops in additional 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.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GH3 has a touchscreen, while the NEX-7 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The GH3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the NEX-7 does not have a selfie-screen.

The Panasonic GH3 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 GH3 writes its imaging data to SDXC cards, while the NEX-7 uses SDXC or Memory Stick PRO Duo cards. The GH3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-7 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Panasonic GH3 vs Sony NEX-7

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process.

It is notable that the GH3 has a headphone jack, which is not present on the NEX-7 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Studio photographers will appreciate that the Panasonic GH3 (unlike the NEX-7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GH3 and the NEX-7 have been discontinued, but can regularly be found used on eBay. The GH3 was replaced by the Panasonic GH4, while the NEX-7 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.


Review summary: Panasonic GH3 vs Sony NEX-7

So what is the bottom line? Is the Panasonic GH3 better than the Sony NEX-7 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Is somewhat more recent (announced 1 year after the NEX-7).

ilogo

Reasons to prefer the Sony Alpha NEX-7:

  • More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1746k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.67x).
  • More detailed LCD: Has a higher resolution rear screen (921k vs 614k dots).
  • Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (120x67mm vs 133x93mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 150g or 27 percent) and is thus easier to take along.
  • More heavily discounted: Has been on the market for longer (launched in August 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (12 points each). 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GH3 12:12 NEX-7

How about other alternatives? Do the specifications of the Panasonic GH3 and the Sony NEX-7 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the GH3 or the NEX-7 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.

Expert reviews: Panasonic GH3 vs Sony NEX-7

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
