Panasonic GF7 vs Sony NEX-F3
The Panasonic Lumix DMC-GF7 and the Sony Alpha NEX-F3 are two digital cameras that were revealed to the public, respectively, in January 2015 and May 2012. Both the GF7 and the NEX-F3 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GF7) and an APS-C (NEX-F3) sensor. The Panasonic has a resolution of 15.8 megapixels, whereas the Sony provides 16 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-GF7 and the Sony Alpha NEX-F3? 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 GF7 and the Sony NEX-F3 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The GF7 can be obtained in two different colors (black, pink), while the NEX-F3 is available in three color-versions (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-F3 is notably larger (13 percent) than the Panasonic GF7. Moreover, the NEX-F3 is markedly heavier (18 percent) than the GF7. In this context, it is worth noting that neither the GF7 nor the NEX-F3 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. 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 (GF7) and the Sony E-Mount Lens Catalog (NEX-F3). 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. 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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GF7 was launched at a somewhat lower price (by 17 percent) than the NEX-F3, which makes it more attractive for photographers on a tight budget. 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.
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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GF7 features a Four Thirds sensor and the Sony NEX-F3 an APS-C sensor. The sensor area in the NEX-F3 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 GF7 has a native 4:3 aspect ratio, while the one in the NEX-F3 offers a 3:2 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 16MP, the NEX-F3 offers a higher resolution than the GF7 (15.8MP), but the NEX-F3 nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 3.77μm for the GF7) due to its larger sensor. However, the GF7 is a much more recent model (by 2 years and 8 months) than the NEX-F3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The Panasonic Lumix DMC-GF7 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha NEX-F3 are ISO 100 to ISO 16000 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GF7 provides a higher frame rate than the NEX-F3. It can shoot video footage at 1080/60p, while the Sony is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. The GF7 and the NEX-F3 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. That said, the NEX-F3 can be equipped with an optional viewfinder – the FDA-EV1S. The table below summarizes some of the other core capabilities of the Panasonic GF7 and Sony NEX-F3 in connection with corresponding information for a sample of similar cameras.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GF7 has a touchscreen, while the NEX-F3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 GF7 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 GF7 writes its imaging data to SDXC cards, while the NEX-F3 uses SDXC or Memory Stick PRO Duo cards. The GF7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-F3 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-GF7 and Sony Alpha NEX-F3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the GF7 offers wifi support, while the NEX-F3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the GF7 and the NEX-F3 have been discontinued, but can regularly be found used on eBay. The GF7 was replaced by the Panasonic GX850, while the NEX-F3 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.
So how do things add up? Is there a clear favorite between the Panasonic GF7 and the Sony NEX-F3? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DMC-GF7:
- Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (107x65mm vs 117x67mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 48g or 15 percent) and hence easier to carry around.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.

Reasons to prefer the Sony Alpha NEX-F3:
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Gets more shots (470 versus 230) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in May 2012).
If the count of relative strengths (bullet points above) is taken as a measure, the GF7 emerges as the winner of the contest (11 : 9 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the GF7 and the NEX-F3 in practical situations. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
