Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Panasonic GM1 was launched in the US market at a price of $749. 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 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

The Panasonic GM1 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 GM1 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

Panasonic GM1 sensor measures

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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Expert reviews

While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the GM1 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 why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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

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. Also, please note that some of the review sites have changed their methodology and reporting over time.

Panasonic GM1 FAQ

Below are some additional questions and answers concerning some particular features of the GM1.

What type of imaging sensor is used in the GM1?

The camera is build around 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 GM1 with the Venus IX image processor.

What is the ISO sensitivity range of the GM1?

The camera has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 125-25600.

What is the life expectancy of the shutter in the Panasonic Lumix DMC-GM1?

Panasonic does not publish a shutter rating for the GM1. 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 GM1?

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-GM1 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 GM1?

The GM1 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 GM1 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.

Does the Panasonic GM1 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 GM1 use?

The camera gets its power from the DMW-BLH7 (here at amazon), which is a rechargeable Lithium-Ion power pack.
