The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic G3 was launched in the US market at a price of $599. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 G3 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 G3 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

Panasonic G3 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 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 G3 indeed provides movie recording capabilities. The highest resolution format that the G3 can use is 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G3 has an electronic viewfinder with a resolution of 1440k 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 G3 along with similar information for a selection of comparators.

One convenient feature of the G3 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.

Expert reviews

While the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G3 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 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).

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

The review scores listed above should be treated 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.

Panasonic G3 FAQ

Below are some additional questions and answers concerning some particular features of the G3.

What type of imaging sensor is used in the G3?

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 G3 with the Venus FHD image processor.

What is the ISO sensitivity range of the G3?

The camera has a native sensitivity range from ISO 160 to ISO 6400.

Does the camera have a selfie-friendly screen?

Yes, the LCD-screen of the G3 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-G3?

Panasonic does not publish a shutter rating for the G3. 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.

Does the Panasonic G3 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 G3's flash sync speed is 1/160 sec.

Which battery does the G3 use?

The camera gets its power from the DMW-BLD10 (here at amazon), which is a rechargeable Lithium-Ion power pack.
