The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic GX7 was launched in the US market at a price of $999. 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 with a 35mm slide

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

The Panasonic GX7 features a Four Thirds sensor and has a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the Panasonic GX7 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

Consistent information on actual sensor performance is available from DXO Mark for most 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GX7 indeed provides movie recording capabilities. The highest resolution format that the GX7 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX7 has an electronic viewfinder with a resolution of 2760k dots. The viewfinder offers a field of view of 100% and a magnification of 0.70x. The tables below summarize some of the other core capabilities of the Panasonic GX7 in connection with corresponding information for a sample of similar cameras.

The LCD screen on the Panasonic Lumix DMC-GX7 is flexibly attached to the body. In particular, the LCD can be tilted vertically to facilitate odd-angle shots in landscape orientation. This tilting design is often preferred, for example, by street photographers to a fully articulated, swivel type of LCD attachment, as it is more unobtrusive during shooting than a screen that flips out to the side.

One convenient feature of the GX7 is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.

Connection comparison

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-GX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX7 offers wifi support. Wifi can be a very convenient means to transfer image data to an off-camera location.

Expert reviews

While the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GX7 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. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

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. 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.
