Panasonic GF3 vs Sony A7
The Panasonic Lumix DMC-GF3 and the Sony Alpha A7 are two digital cameras that were revealed to the public, respectively, in June 2011 and October 2013. Both the GF3 and the A7 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GF3) and a full frame (A7) sensor. The Panasonic has a resolution of 12 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-GF3 and the Sony Alpha A7? 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.
An illustration of the physical size and weight of the Panasonic GF3 and the Sony A7 is provided 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 size dimensions are rounded to the nearest millimeter.
The GF3 can be obtained in five different colors (black, brown, pink, red, white), while the A7 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 is considerably larger (65 percent) than the Panasonic GF3. Moreover, the A7 is substantially heavier (80 percent) than the GF3. It is noteworthy in this context that the A7 is splash and dust-proof, while the GF3 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 (GF3) and the Sony FE Lens Catalog (A7). 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 GF3 gets 300 shots out of its DMW-BLE9 battery, while the A7 can take 340 images on a single charge of its NP-FW50 power pack. The power pack in the A7 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.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GF3 was launched at a markedly lower price (by 68 percent) than the A7, 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.
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. 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 GF3 features a Four Thirds sensor and the Sony A7 a full frame sensor. The sensor area in the A7 is 280 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 GF3 has a native 4:3 aspect ratio, while the one in the A7 offers a 3:2 aspect.
With 24MP, the A7 offers a higher resolution than the GF3 (12MP), but the A7 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 4.33μm for the GF3) due to its larger sensor. Moreover, the A7 is a much more recent model (by 2 years and 4 months) than the GF3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic GF3 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The A7 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Panasonic Lumix DMC-GF3 has a native sensitivity range from ISO 160 to ISO 6400. The corresponding ISO settings for the Sony Alpha A7 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.
For many 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 A7 offers substantially better image quality than the GF3 (overall score 41 points higher). The advantage is based on 4.2 bits higher color depth, 4.2 EV in additional dynamic range, and 2.3 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7 provides a faster frame rate than the GF3. It can shoot movie footage at 1080/60p, while the Panasonic is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A7 has an electronic viewfinder (2400k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF3 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GF3 and Sony A7 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The GF3 has one, while the A7 does not. While the built-in flash of the GF3 is not very powerful, it can at times be useful as a fill-in light.
The GF3 writes its imaging data to SDXC cards, while the A7 uses SDXC or Memory Stick PRO Duo cards. The A7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GF3 cannot take advantage of Ultra High Speed SD cards.
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. The table below provides an overview of the connectivity of the Panasonic Lumix DMC-GF3 and Sony Alpha A7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the GF3 does not provide wifi capability.
Both the GF3 and the A7 have been discontinued, but can regularly be found used on eBay. The GF3 was replaced by the Panasonic GF5, while the A7 was followed by the Sony A7 II. 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.
So what is the bottom line? Is the Panasonic GF3 better than the Sony A7 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-GF3:
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 is the clear winner of the contest (22 : 6 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 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.
How about other alternatives? Do the specifications of the Panasonic GF3 and the Sony A7 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 incomplete and does no justice, for example, to the way the GF3 or the A7 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.
This is why hands-on reviews by experts are important. 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
