Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GF3 and the Sony Alpha A6300? 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

The side-by-side display below illustrates the physical size and weight of the Panasonic GF3 and the Sony A6300. 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 dimensions are rounded to the nearest millimeter.

The GF3 can be obtained in five different colors (black, brown, pink, red, white), while the A6300 is available in two color-versions (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6300 is notably larger (11 percent) than the Panasonic GF3. Moreover, the A6300 is substantially heavier (53 percent) than the GF3. It is noteworthy in this context that the A6300 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 E-Mount Lens Catalog (A6300). 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 Panasonic DMW-BLE9 battery, while the A6300 can take 400 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A6300 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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 GF3 was launched at a markedly lower price (by 45 percent) than the A6300, 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.

Sensor comparison

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. 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 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 A6300 an APS-C sensor. The sensor area in the A6300 is 63 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 GF3 has a native 4:3 aspect ratio, while the one in the A6300 offers a 3:2 aspect.

With 24MP, the A6300 offers a higher resolution than the GF3 (12MP), but the A6300 has smaller individual pixels (pixel pitch of 3.91μm versus 4.33μm for the GF3). Yet, the A6300 is a much more recent model (by 4 years and 7 months) than the GF3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A6300 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6300 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 A6300 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 A6300 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

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.

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 A6300 offers substantially better image quality than the GF3 (overall score 35 points higher). The advantage is based on 3.8 bits higher color depth, 3.6 EV in additional dynamic range, and 1.6 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A6300 provides a better video resolution than the GF3. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A6300 has an electronic viewfinder (2359k 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 following table reports on some other key feature differences and similarities of the Panasonic GF3, the Sony A6300, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GF3 has a touchscreen, while the A6300 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 A6300 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 GF3 writes its imaging data to SDXC cards, while the A6300 uses SDXC or Memory Stick PRO Duo cards. The A6300 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.

Connectivity comparison

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 A6300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A6300 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 A6300 have been discontinued, but can regularly be found used on ebay. The GF3 was replaced by the Panasonic GF5, while the A6300 was followed by the Sony A6500. Further information on the features and operation of the GF3 and A6300 can be found, respectively, in the Panasonic GF3 Manual (free pdf) or the online Sony A6300 Manual.

Review summary

So how do things add up? Is the Panasonic GF3 better than the Sony A6300 or vice versa? The listing below highlights the relative strengths of the two models.

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 individual advantages (bullet points above) is taken as a guide, the A6300 is the clear winner of the contest (21 : 4 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.

How about other alternatives? Do the specifications of the Panasonic GF3 and the Sony A6300 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 says little about, for example, the shooting experience and imaging performance of the GF3 and the A6300 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
