The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic GH3 was launched in the US market at a price of $1,299. 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 associated with larger, more expensive camera bodies and lenses.
The Panasonic GH3 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 GH3 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
For most cameras, data on sensor performance has been reported by DXO Mark. 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 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. The GH3 indeed provides movie recording capabilities. The highest resolution format that the GH3 can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the GH3 has an electronic viewfinder with a resolution of 1746k dots. The viewfinder offers a field of view of 100% and a magnification of 0.67x. The tables below summarize some of the other core capabilities of the Panasonic GH3 in connection with corresponding information for a sample of similar cameras.

One convenient feature of the GH3 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-GH3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH3 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GH3. 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 (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
Panasonic GH3 FAQ
Below are some additional questions and answers concerning some particular features of the GH3.
What is the technology behind the imaging sensor in the GH3?
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 GH3 with the Venus VII FHD image processor.
What is the ISO sensitivity range of the GH3?
The camera has a native sensitivity range from ISO 200 to ISO 12800, which can be extended to ISO 125-25600.
Does the camera have a selfie-friendly screen?
Yes, the LCD-screen of the GH3 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-GH3?
Panasonic does not publish a shutter rating for the GH3. Yet, shutters in comparable cameras from other manufacturers are said to be good for at least 200 000 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 200 000 shots over, say, three years, one would have to take about 200 pictures each and every day.
Do I need to purchase an external camera trigger to shoot time-lapse sequences?
No, the Panasonic Lumix DMC-GH3 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.
Does the Panasonic GH3 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 GH3's flash sync speed is 1/160 sec.
Does the Panasonic GH3 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 GH3 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 GH3?
Yes, Panasonic offers the DMW-BGGH3 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
