Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GF2 and the Panasonic Lumix DMC-GM1? 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 physical size and weight of the Panasonic GF2 and the Panasonic GM1 are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.
The GF2 can be obtained in four different colors (black, silver, red, white), while the GM1 is available in three color-versions (black, silver, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM1 is notably smaller (29 percent) than the Panasonic GF2. Moreover, the GM1 is markedly lighter (34 percent) than the GF2. In this context, it is worth noting that neither the GF2 nor the GM1 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras 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 GF2 was launched at a markedly lower price (by 27 percent) than the GM1, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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.
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 GM1 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the GF2. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the GM1 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 GF2). However, it should be noted that the GM1 is much more recent (by 2 years and 11 months) than the GF2, 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 GM1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GM1 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 GF2 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-GF2 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DMC-GM1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 125-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the GM1 offers substantially better image quality than the GF2 (overall score 12 points higher). The advantage is based on 1.1 bits higher color depth, 1.4 EV in additional dynamic range, and 0.4 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60i).
Beyond body and sensor, cameras can and do differ across a range of features. The GF2 and the GM1 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. That said, the GF2 can be equipped with an optional viewfinder – the DMW-LVF1. The table below summarizes some of the other core capabilities of the Panasonic GF2 and Panasonic GM1 in connection with corresponding information for a sample of similar cameras.

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 GM1 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 Panasonic GM1 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the GF2 and the GM1 write their files to SDXC cards. The GM1 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.
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 Panasonic Lumix DMC-GM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GF2 has a hotshoe, while the GM1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the GF2 and the GM1 have been discontinued, but can regularly be found used on eBay. The GF2 was replaced by the Panasonic GF3, while the GM1 was followed by the Panasonic GM5. 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 what conclusions can be drawn? Is the Panasonic GF2 better than the Panasonic GM1 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Panasonic Lumix DMC-GF2:
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Can take more shots (300 versus 230) on a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More affordable: Was introduced into a lower priced category (27 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in November 2010).
Advantages of the Panasonic Lumix DMC-GM1:
- More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
- Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
- More detailed LCD: Has a higher resolution rear screen (1036k vs 460k dots).
- Faster burst: Shoots at higher frequency (5 vs 2.6 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More compact: Is smaller (99x55mm vs 113x68mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 106g or 34 percent) and is thus easier to take along.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 2 years and 11 months of technical progress since the GF2 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the GM1 is the clear winner of the contest (14 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 GF2 and the Panasonic GM1 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 GF2 or the GM1. 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 following table reports the overall ratings of the cameras as published by some of the major 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
