The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic G100 was launched in the US market at a price of $649. 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. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 G100 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 G100 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

Panasonic G100 sensor measures

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G100 indeed provides movie recording capabilities. The highest resolution format that the G100 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G100 has an electronic viewfinder with a resolution of 3680k dots. The viewfinder offers a field of view of 100% and a magnification of 0.73x. The following tables report on some other key feature differences and similarities of the Panasonic G100 and comparable cameras.

One convenient feature of the G100 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 DC-G100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G100 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.

Expert reviews

While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G100 handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.

Panasonic G100 FAQ

Below are some additional questions and answers concerning some particular features of the G100.

What technology is the imaging sensor in the G100 based on?

The camera is build around a Live MOS (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 G100 with the Venus image processor.

What is the ISO sensitivity range of the G100?

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 G100 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 DC-G100?

Panasonic does not publish a shutter rating for the G100. 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 G100?

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-G100 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 G100?

The G100 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 G100 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 G100's flash sync speed is 1/200 sec.

Does the Panasonic G100 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 G100 use?

The camera gets its power from the DMW-BLG10 (here at amazon), which is a rechargeable Lithium-Ion power pack.
