Panasonic G100 vs GF1
The Panasonic Lumix DC-G100 (called Panasonic G110 in some regions) and the Panasonic Lumix DMC-GF1 are two digital cameras that were revealed to the public, respectively, in June 2020 and September 2009. Both the G100 and the GF1 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G100 has a resolution of 20.2 megapixels, whereas the GF1 provides 12 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DC-G100 and the Panasonic Lumix DMC-GF1? 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 G100 and the Panasonic GF1 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 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 GF1 is notably smaller (12 percent) than the Panasonic G100. However, the GF1 is markedly heavier (9 percent) than the G100. In this context, it is worth noting that neither the G100 nor the GF1 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 G100 gets 270 shots out of its DMW-BLG10 battery, while the GF1 can take 380 images on a single charge of its DMW-BLB13 power pack. The power pack in the G100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
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, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 G100 was launched at a somewhat lower price (by 13 percent) than the GF1, which makes it more attractive for photographers on a tight budget. 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. 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. 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 are more costly to manufacture and tend to 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 G100 offers a higher resolution of 20.2 megapixels, compared with 12 MP of the GF1. This megapixels advantage translates into a 30 percent gain in linear resolution. On the other hand, these sensor specs imply that the G100 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.33μm for the GF1). In this context, it should be noted, however, that the G100 is much more recent (by 10 years and 9 months) than the GF1, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the G100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic G100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G100 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Panasonic GF1 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 Panasonic Lumix DC-G100 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GF1 are ISO 100 to ISO 3200 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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, but the G100 provides a higher video resolution than the GF1. It can shoot video footage at 4K/30p, while the GF1 is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G100 has an electronic viewfinder (3680k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF1 relies on live view and the rear LCD for framing. That said, the GF1 can be equipped with an optional viewfinder – the DMW-LVF1. The adjacent table lists some of the other core features of the Panasonic G100 and Panasonic GF1 along with similar information for a selection of comparators.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G100 has a touchscreen, while the GF1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the GF1 does not have a selfie-screen.
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 G100 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 G100 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.
The G100 writes its imaging data to SDXC cards, while the GF1 uses SDHC cards. The G100 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 DC-G100 and Panasonic Lumix DMC-GF1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G100 has a microphone port, which is missing on the GF1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The G100 is a recent model that features in the current product line-up of Panasonic. In contrast, the GF1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GF1 was succeeded by the Panasonic DMC-GF2. 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? Which of the two cameras – the Panasonic G100 or the Panasonic GF1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Advantages of the Panasonic Lumix DC-G100:
- More detail: Offers more megapixels (20.2 vs 12MP) with a 30% higher linear resolution.

- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- More compact: Is smaller (119x71mm vs 116x83mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (380 versus 270) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in September 2009).
If the count of relative strengths (bullet points above) is taken as a measure, the G100 is the clear winner of the match-up (19 : 5 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the G100 and the GF1 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
