Panasonic GX1 vs Sony NEX-F3
The Panasonic Lumix DMC-GX1 and the Sony Alpha NEX-F3 are two digital cameras that were officially introduced, respectively, in November 2011 and May 2012. Both the GX1 and the NEX-F3 are mirrorless interchangeable lens cameras that are based on a Four Thirds (GX1) 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-GX1 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 GX1 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 views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The NEX-F3 can be obtained in three different colors (black, silver, white), while the GX1 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 Panasonic GX1 and the Sony NEX-F3 are of equal size. However, the NEX-F3 is slightly lighter (1 percent) than the GX1. In this context, it is worth noting that neither the GX1 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 (GX1) 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The NEX-F3 was launched at a somewhat lower price (by 14 percent) than the GX1, which makes it more attractive for photographers on a tight budget. 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.
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 GX1 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 GX1 has a native 4:3 aspect ratio, while the one in the NEX-F3 offers a 3:2 aspect.
With 16MP, the NEX-F3 offers a higher resolution than the GX1 (15.8MP), but the NEX-F3 nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 3.77μm for the GX1) due to its larger sensor. Moreover, the NEX-F3 is a somewhat more recent model (by 6 months) than the GX1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The Panasonic Lumix DMC-GX1 has a native sensitivity range from ISO 160 to ISO 12800. 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 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"). Of the two cameras under consideration, the NEX-F3 offers substantially better image quality than the GX1 (overall score 18 points higher). The advantage is based on 1.9 bits higher color depth, 1.7 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX1 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.
Apart from body and sensor, cameras can and do differ across a range of features. The GX1 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. However, optional viewfinders – the DMW-LVF2 for the GX1 and the FDA-EV1S for the NEX-F3 – are available as accessories. The table below summarizes some of the other core capabilities of the Panasonic GX1 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 GX1 has a touchscreen, while the NEX-F3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The NEX-F3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the GX1 does not have a selfie-screen.
The GX1 writes its imaging data to SDXC cards, while the NEX-F3 uses SDXC or Memory Stick PRO Duo cards. The GX1 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-GX1 and Sony Alpha NEX-F3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GX1 and the NEX-F3 have been discontinued, but can regularly be found used on eBay. The GX1 was replaced by the Panasonic GX7, 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 what conclusions can be drawn? Which of the two cameras – the Panasonic GX1 or the Sony NEX-F3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-GX1:
- Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been on the market for longer (launched in November 2011).
Advantages of the Sony Alpha NEX-F3:
- Better image quality: Scores substantially higher (18 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.7 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (5.5 vs 4.2 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (470 versus 320) out of a single battery charge.
- More affordable: Was released into a lower priced segment (14 percent cheaper at launch).
- More modern: Was introduced somewhat (6 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the NEX-F3 is the clear winner of the contest (11 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GX1 or the NEX-F3. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
