Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GF2 and the Sony Alpha ALT-A99 II? 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 GF2 and the Sony A99 II. 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 GF2 can be obtained in four different colors (black, silver, red, white), while the A99 II is only available in black.

Size Panasonic GF2 vs Sony A99 II
Compare GF2 versus A99 II top
Comparison GF2 or A99 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A99 II is considerably larger (94 percent) than the Panasonic GF2. Moreover, the A99 II is substantially heavier (174 percent) than the GF2. It is noteworthy in this context that the A99 II is splash and dust-proof, while the GF2 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the GF2 gets 300 shots out of its DMW-BLD10 battery, while the A99 II can take 490 images on a single charge of its NP-FM500H 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 add-on or interchangeable lenses or optional viewfinders.

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 GF2 was launched at a markedly lower price (by 83 percent) than the A99 II, 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 GF2 features a Four Thirds sensor and the Sony A99 II a full frame sensor. The sensor area in the A99 II is 283 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 GF2 has a native 4:3 aspect ratio, while the one in the A99 II offers a 3:2 aspect.

Panasonic GF2 and Sony A99 II sensor measures

With 42.2MP, the A99 II offers a higher resolution than the GF2 (12MP), but the A99 II nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 4.33μm for the GF2) due to its larger sensor. Moreover, the A99 II is a much more recent model (by 5 years and 10 months) than the GF2, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the A99 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A99 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A99 II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Panasonic GF2 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 A99 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Panasonic Lumix DMC-GF2 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Alpha ALT-A99 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.

In terms of underlying technology, the GF2 is build around a CMOS sensor, while the A99 II uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

GF2 versus A99 II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 A99 II offers substantially better image quality than the GF2 (overall score 38 points higher). The advantage is based on 4.2 bits higher color depth, 3.1 EV in additional dynamic range, and 2.2 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A99 II provides a better video resolution than the GF2. 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 variety of features. For example, the A99 II has an electronic viewfinder (2400k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF2 relies on live view and the rear LCD for framing. That said, the GF2 can be equipped with an optional viewfinder – the DMW-LVF1. The adjacent table lists some of the other core features of the Panasonic GF2 and Sony A99 II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The GF2 has one, while the A99 II does not. While the built-in flash of the GF2 is not very powerful, it can at times be useful as a fill-in light.

The A99 II 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 GF2 does not have a selfie-screen.

The GF2 writes its imaging data to SDXC cards, while the A99 II uses SDXC or Memory Stick PRO Duo cards. The A99 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the GF2 only has one slot. The A99 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GF2 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-GF2 and Sony Alpha ALT-A99 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A99 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the GF2 does not provide wifi capability.

Studio photographers will appreciate that the Sony A99 II (unlike the GF2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the GF2 and the A99 II have been discontinued, but can regularly be found used on ebay. The GF2 was replaced by the Panasonic GF3, while the A99 II does not have a direct successor. Further information on the features and operation of the GF2 and A99 II can be found, respectively, in the Panasonic GF2 Manual (free pdf) or the online Sony A99 II Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the A99 II is the clear winner of the contest (27 : 8 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

GF2 08:27 A99 II

How about other alternatives? Do the specifications of the Panasonic GF2 and the Sony A99 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GF2 or the A99 II. 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 where reviews by experts come in. 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated with care, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
