Panasonic G7 vs G2
The Panasonic Lumix DMC-G7 and the Panasonic Lumix DMC-G2 are two digital cameras that were officially introduced, respectively, in May 2015 and March 2010. Both the G7 and the G2 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The G7 has a resolution of 15.8 megapixels, whereas the G2 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 DMC-G7 and the Panasonic Lumix DMC-G2? 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 G7 and the Panasonic G2. 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.
The G7 can be obtained in two different colors (black, silver), while the G2 is available in three color-versions (black, blue, red).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G2 is somewhat smaller (3 percent) than the Panasonic G7. However, the G2 is slightly heavier (4 percent) than the G7. In this context, it is worth noting that neither the G7 nor the G2 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 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G2 was somewhat cheaper (by 8 percent) than the G7 at launch, but both cameras fall into the same price category. 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. 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. 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 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 G7 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the G2. This megapixels advantage translates into a 15 percent gain in linear resolution. On the other hand, these sensor specs imply that the G7 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 G2). In this context, it should be noted, however, that the G7 is much more recent (by 5 years and 2 months) than the G2, 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 G7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7 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 G2 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-G7 has a native sensitivity range from ISO 160 to ISO 25600. The corresponding ISO settings for the Panasonic Lumix DMC-G2 are ISO 100 to ISO 6400 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7 provides a higher video resolution than the G2. It can shoot video footage at 4K/30p, while the G2 is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the G7 offers a substantially higher resolution than the one in the G2 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Panasonic G7 and Panasonic G2 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 G7 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 G7 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 G7 and the G2 write their files to SDXC cards. The G7 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G2 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-G7 and Panasonic Lumix DMC-G2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7 has a microphone port, which is missing on the G2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the G7 and the G2 have been discontinued, but can regularly be found used on eBay. The G2 was replaced by the Panasonic G3, while the G7 was followed by the Panasonic G85. 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 G7 better than the Panasonic G2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-G7:
- More detail: Offers more megapixels (15.8 vs 12MP) with a 15% higher linear resolution.
- Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 460k dots).
- Faster burst: Shoots at higher frequency (7 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.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
- More modern: Reflects 5 years and 2 months of technical progress since the G2 launch.
Advantages of the Panasonic Lumix DMC-G2:
- More heavily discounted: Has been around for much longer (launched in March 2010).
If the number of relative strengths (bullet points above) is taken as a guide, the G7 is the clear winner of the match-up (11 : 1 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 G7 and the Panasonic G2 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 incomplete and does no justice, for example, to the way the G7 or the G2 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 expert reviews 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
