Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GF1 and the Panasonic Lumix DMC-GF2? 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 GF1 and the Panasonic GF2. 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 GF1 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 GF2 is notably smaller (9 percent) than the Panasonic GF1. Moreover, the GF2 is markedly lighter (19 percent) than the GF1. In this context, it is worth noting that neither the GF1 nor the GF2 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. 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 GF1 gets 380 shots out of its Panasonic DMW-BLB13 battery, while the GF2 can take 300 images on a single charge of its Panasonic DMW-BLD10 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 27 percent) than the GF1, 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12 megapixels. This similarity in sensor specs implies that both the GF1 and the GF2 have the same pixel density, as well as the same pixel size. It should, however, be noted that the GF2 is a somewhat more recent model (by 1 year and 2 months) than the GF1, and its sensor might have benefitted from technological advances during this time.

The Panasonic Lumix DMC-GF1 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DMC-GF2 are ISO 100 to ISO 6400 (no boost).

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.

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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GF2 provides a better video resolution than the GF1. It can shoot movie footage at 1080/60i, while the GF1 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The GF1 and the GF2 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-LVF1 for the GF1 and the DMW-LVF1 for the GF2 – are available as accessories. The adjacent table lists some of the other core features of the Panasonic GF1 and Panasonic GF2 along with similar information for a selection of comparators.

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 GF2 has a touchscreen, while the GF1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The GF1 writes its imaging data to SDHC cards, while the GF2 uses SDXC 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-GF1 and Panasonic Lumix DMC-GF2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GF1 and the GF2 have been discontinued, but can regularly be found used on ebay. The GF1 was replaced by the Panasonic DMC-GF2, while the GF2 was followed by the Panasonic GF3. Further information on the features and operation of the GF1 and GF2 can be found, respectively, in the Panasonic GF1 Manual (free pdf) or the online Panasonic GF2 Manual.

Review summary

So how do things add up? Which of the two cameras – the Panasonic GF1 or the Panasonic GF2 – 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.

Arguments in favor of the Panasonic Lumix DMC-GF1:

• Faster burst: Shoots at higher frequency (3 vs 2.6 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (380 versus 300) on a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in September 2009).

Advantages of the Panasonic Lumix DMC-GF2:

• Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Less heavy: Has a lower weight (by 75g or 19 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 2 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the GF2 emerges as the winner of the match-up (5 : 3 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.

How about other alternatives? Do the specifications of the Panasonic GF1 and the Panasonic GF2 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 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 GF1 or the GF2. 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.

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.
