The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic G9 was launched in the US market at a price of $1,699. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
The Panasonic G9 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 G9 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 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 G9 indeed provides movie recording capabilities. The highest resolution format that the G9 can use is 4K/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G9 has an electronic viewfinder with a resolution of 3680k dots. The viewfinder offers a field of view of 100% and a magnification of 0.83x. The tables below summarize some of the other core capabilities of the Panasonic G9 in connection with corresponding information for a sample of similar cameras.

One useful feature of the G9 is a presence of a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
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-G9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G9 has a microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G9. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
Panasonic G9 FAQ
Below are some additional questions and answers concerning some particular features of the G9.
What technology is the imaging sensor in the G9 based on?
The camera features a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.
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 G9 with the Venus 10 image processor.
What is the ISO sensitivity range of the G9?
The camera has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600.
Does the camera have a selfie-friendly screen?

What is the life expectancy of the shutter in the Panasonic Lumix DC-G9?
Panasonic mentions a shutter rating of 200 000 actuations for the G9. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the G9 over, say, three years, one would have to take about 200 pictures each and every day.
Is completely silent shooting possible with the Panasonic G9?
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-G9 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 G9?
The G9 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 G9 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 G9's flash sync speed is 1/250 sec.
Does the Panasonic G9 support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-II cards, which provide for data transfer speed of up to 312 MB/s, in both of its card slots.
Which battery does the G9 use?
The camera gets its power from the DMW-BLF19 (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the G9?
Yes, Panasonic offers the DMW-BGG9 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
