Panasonic G1 vs GF7
The Panasonic Lumix DMC-G1 and the Panasonic Lumix DMC-GF7 are two digital cameras that were officially introduced, respectively, in September 2008 and January 2015. Both the G1 and the GF7 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G1 has a resolution of 12 megapixels, whereas the GF7 provides 15.8 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 DMC-G1 and the Panasonic Lumix DMC-GF7? 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.
An illustration of the physical size and weight of the Panasonic G1 and the Panasonic GF7 is provided in the side-by-side display below. 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 width, height and depth measures are rounded to the nearest millimeter.
The GF7 can be obtained in two different colors (black, pink), while the G1 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 GF7 is considerably smaller (33 percent) than the Panasonic G1. Moreover, the GF7 is markedly lighter (26 percent) than the G1. In this context, it is worth noting that neither the G1 nor the GF7 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 want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 GF7 was launched at a somewhat lower price (by 17 percent) than the G1, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 GF7 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the G1. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the GF7 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 G1). However, it should be noted that the GF7 is much more recent (by 6 years and 4 months) than the G1, 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 GF7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GF7 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Panasonic G1 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 DMC-G1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Panasonic Lumix DMC-GF7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The GF7 indeed provides for movie recording, while the G1 does not. The highest resolution format that the GF7 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GF7 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Panasonic G1 and Panasonic GF7 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 GF7 has a touchscreen, while the G1 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
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 GF7 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 G1 writes its imaging data to SDHC cards, while the GF7 uses SDXC cards. The GF7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1 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-G1 and Panasonic Lumix DMC-GF7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the G1 has a hotshoe, while the GF7 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the G1 and the GF7 have been discontinued, but can regularly be found used on eBay. The G1 was replaced by the Panasonic G2, while the GF7 was followed by the Panasonic GX850. 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 G1 better than the Panasonic GF7 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Panasonic Lumix DMC-G1:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/500s) to freeze action.
- Longer lasting: Can take more shots (410 versus 230) on a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been available for much longer (launched in September 2008).
Reasons to prefer the Panasonic Lumix DMC-GF7:
- More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 15%.
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (5.8 vs 3 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (107x65mm vs 124x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 94g or 26 percent) and is thus easier to take along.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
- More modern: Reflects 6 years and 4 months of technical progress since the G1 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the GF7 is the clear winner of the contest (13 : 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 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 G1 and the Panasonic GF7 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G1 or the GF7 perform in practice. 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 (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 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.
