Body comparison: Panasonic GH3 vs GX7
An illustration of the physical size and weight of the Panasonic GH3 and the Panasonic GX7 is provided 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 dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the GH3 – represents the basis for the calculations across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX7 is notably smaller (29 percent) than the Panasonic GH3. Moreover, the GX7 is markedly lighter (27 percent) than the GH3. It is worth mentioning in this context that the GH3 is splash and dust resistant, while the GX7 does not feature any corresponding weather-sealing.
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.

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 GX7 was launched at a somewhat lower price (by 23 percent) than the GH3, 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.
Sensor comparison: Panasonic GH3 vs GX7
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. 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 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 GH3 offers a slightly higher resolution of 15.9 megapixels, compared with 15.8 MP of the GX7. This megapixels advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the GH3 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 3.77μm for the GX7). Moreover, it should be noted that the GX7 is a somewhat more recent model (by 10 months) than the GH3, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.
The Panasonic Lumix DMC-GH3 has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Panasonic Lumix DMC-GX7 are ISO 125 to ISO 25600 (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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Feature comparison: Panasonic GH3 vs GX7
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the GX7 offers a substantially higher resolution than the one in the GH3 (2760k vs 1746k dots). The adjacent table lists some of the other core features of the Panasonic GH3 and Panasonic GX7 along with similar information for a selection of comparators.

One feature that differentiates the GX7 and the GH3 is in-body image stabilization (IBIS). The GX7 reduces the risk of handshake-induced blur with all attached lenses, while the GH3 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.The GH3 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 GX7 does not have a selfie-screen.
The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the GX7 features 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).
Concerning the storage of imaging data, both the GH3 and the GX7 write their files to SDXC cards.
Connectivity comparison: Panasonic GH3 vs GX7
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 review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
