The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic GX9 was launched in the US market at a price of $849. 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 size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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.
The Panasonic GX9 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 GX9 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 are not only capable of taking still images, but also of capturing video footage. The GX9 indeed provides movie recording capabilities. The highest resolution format that the GX9 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the GX9 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 adjacent tables list some of the other core features of the Panasonic GX9 along with similar information for a selection of comparators.

One convenient feature of the GX9 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.
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 DC-GX9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX9 offers wifi support. Wifi can be a very convenient means to transfer image data to an off-camera location.
While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GX9 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
Panasonic GX9 FAQ
Below are some additional questions and answers concerning some particular features of the GX9.
What is the technology behind the imaging sensor in the GX9?
The camera has a CMOS (Complementary Metal–Oxide–Semiconductor) sensor at its core.
Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?
Panasonic equipped the GX9 with the Venus image processor.
What is the ISO sensitivity range of the GX9?
The camera has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600.
What is the life expectancy of the shutter in the Panasonic Lumix DC-GX9?
Panasonic does not publish a shutter rating for the GX9. Yet, shutters in comparable cameras from other manufacturers are said to be good for at least 100 000 actuations. It should be noted, though, that this number represents a Mean Time before Failure. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust an expected shutter life of 100 000 shots over, say, three years, one would have to take about 100 pictures each and every day.
Is completely silent shooting possible with the Panasonic GX9?
The camera has an electronic shutter option, so that it is indeed feasible to capture images without any shutter noise.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Panasonic Lumix DC-GX9 has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.
Is it difficult to use manual focus lenses with the Panasonic GX9?
The GX9 offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.
Does the Panasonic GX9 feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The GX9's flash sync speed is 1/200 sec.
Does the Panasonic GX9 support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).
Which battery does the GX9 use?
The camera gets its power from the DMW-BLG10 (here at amazon), which is a rechargeable Lithium-Ion power pack.
