Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G7 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.

Body comparison: Panasonic G7 vs GF7

The physical size and weight of the Panasonic G7 and the Panasonic GF7 are illustrated 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 G7 can be obtained in two different colors (black, silver), while the GF7 is also available in two color-versions, but different ones (black, pink).

Size Panasonic G7 vs Panasonic GF7
Compare G7 versus GF7 top
Comparison G7 or GF7 rear

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 (35 percent) than the Panasonic G7. Moreover, the GF7 is substantially lighter (35 percent) than the G7. In this context, it is worth noting that neither the G7 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.

Concerning battery life, the G7 gets 350 shots out of its DMW-BLC12 battery, while the GF7 can take 230 images on a single charge of its DMW-BLH7 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The GF7 was launched at a somewhat lower price (by 23 percent) than the G7, 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.

 

Sensor comparison: Panasonic G7 vs GF7

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 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.

Panasonic G7 and Panasonic GF7 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.8 megapixels. This similarity in sensor specs implies that both the G7 and the GF7 have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7 is a somewhat more recent model (by 3 months) than the GF7, and its sensor might have benefitted from technological advances during this time.

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-GF7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

G7 versus GF7 MP

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.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7 provides a higher video resolution than the GF7. It can shoot video footage at 4K/30p, while the GF7 is limited to 1080/60p.

 

Feature comparison: Panasonic G7 vs GF7

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G7 has an electronic viewfinder (2360k 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 following table reports on some other key feature differences and similarities of the Panasonic G7, the Panasonic GF7, and comparable cameras.

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, both cameras under consideration feature an 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 GF7 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 GF7 can use UHS-I cards (up to 104 MB/s).

 

Connectivity comparison: Panasonic G7 vs GF7

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-GF7 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 hotshoe, while the GF7 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the G7 and the GF7 have been discontinued, but can regularly be found used on eBay. The GF7 was replaced by the Panasonic GX850, 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.


Review summary: Panasonic G7 vs GF7

So how do things add up? Which of the two cameras – the Panasonic G7 or the Panasonic GF7 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Panasonic Lumix DMC-G7:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible LCD: Has 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.
  • Faster burst: Shoots at higher frequency (7 vs 5.8 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Can take more shots (350 versus 230) on a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More modern: Is somewhat more recent (announced 3 months after the GF7).


Arguments in favor of the Panasonic Lumix DMC-GF7:

  • More compact: Is smaller (107x65mm vs 125x86mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 144g or 35 percent) and is thus easier to take along.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was released into a lower priced segment (23 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2015).

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 : 5 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.

G7 11:05 GF7

How about other alternatives? Do the specifications of the Panasonic G7 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G7 and the GF7 in practical situations. 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.

Expert reviews: Panasonic G7 vs GF7

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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
