Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GF1 and the Panasonic Lumix DMC-GX1? 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.
The side-by-side display below illustrates the physical size and weight of the Panasonic GF1 and the Panasonic GX1. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX1 is notably smaller (7 percent) than the Panasonic GF1. Moreover, the GX1 is markedly lighter (17 percent) than the GF1. In this context, it is worth noting that neither the GF1 nor the GX1 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. 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 GX1 was somewhat cheaper (by 7 percent) than the GF1 at launch, but both cameras fall into the same price category. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant 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 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.
While the two cameras under review share the same sensor size, the GX1 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the GF1. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.33μm for the GF1). However, it should be noted that the GX1 is much more recent (by 2 years and 2 months) than the GF1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The resolution advantage of the Panasonic GX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX1 for good quality output (200 dots per inch) amounts to 23 x 17.2 inch or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inch or 38.9 x 29.2 cm. The corresponding values for the Panasonic GF1 are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 cm for excellent quality prints.
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-GX1 are ISO 160 to ISO 12800 (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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the GX1 provides a better video resolution than the GF1. It can shoot movie footage at 1080/60p, while the GF1 is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The GF1 and the GX1 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-LVF2 for the GX1 – are available as accessories. The table below summarizes some of the other core capabilities of the Panasonic GF1 and Panasonic GX1 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 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 GX1 uses SDXC cards. The GX1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the GF1 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-GF1 and Panasonic Lumix DMC-GX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the GF1 and the GX1 have been discontinued, but can regularly be found used on eBay. The GF1 was replaced by the Panasonic DMC-GF2, while the GX1 was followed by the Panasonic GX7. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.
So how do things add up? Is the Panasonic GF1 better than the Panasonic GX1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Panasonic Lumix DMC-GF1:
- Longer lasting: Can take more shots (380 versus 320) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in September 2009).
Reasons to prefer the Panasonic Lumix DMC-GX1:
- More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (4.2 vs 3 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 67g or 17 percent) and is thus easier to take along.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 2 years and 2 months of technical progress since the GF1 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the GX1 is the clear winner of the contest (8 : 2 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.
How about other alternatives? Do the specifications of the Panasonic GF1 and the Panasonic GX1 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the GF1 or the GX1. 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.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
