The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic GH4 was launched in the US market at a price of $1,499. 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. 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 more expensive and lead to bigger and heavier cameras and lenses.
The Panasonic GH4 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 GH4 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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The GH4 indeed provides movie recording capabilities. The highest resolution format that the GH4 can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH4 has an electronic viewfinder with a resolution of 2359k dots. The viewfinder offers a field of view of 100% and a magnification of 0.67x. The following tables report on some other key feature differences and similarities of the Panasonic GH4 and comparable cameras.

One convenient feature of the GH4 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 DMC-GH4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH4 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 says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GH4 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted 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.
Panasonic GH4 FAQ
Below are some additional questions and answers concerning some particular features of the GH4.
What technology is the imaging sensor in the GH4 based on?
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 GH4 with the Venus IX image processor.
What is the ISO sensitivity range of the GH4?
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?
Yes, the LCD-screen of the GH4 is flexible and can be turned to be front-facing for capturing selfies.
What is the life expectancy of the shutter in the Panasonic Lumix DMC-GH4?
Panasonic mentions a shutter rating of 200 000 actuations for the GH4. 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 GH4 over, say, three years, one would have to take about 200 pictures each and every day.
Is completely silent shooting possible with the Panasonic GH4?
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 DMC-GH4 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 GH4?
The GH4 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 GH4 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 GH4's flash sync speed is 1/250 sec.
Does the Panasonic GH4 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 GH4 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 GH4?
Yes, Panasonic offers the DMW-BGGH3 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
