The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Olympus E-PM1 was launched in the US market at a price of $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 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 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
The Olympus E-PM1 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 Olympus E-PM1 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of alternatives.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The E-PM1 indeed provides movie recording capabilities. The highest resolution format that the E-PM1 can use is 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. The adjacent tables list some of the other core features of the Olympus E-PM1 along with similar information for a selection of comparators.

One feature that differentiates the E-PM1 from many older cameras is in-body image stabilization (IBIS). The E-PM1 reduces the risk of handshake-induced blur with all attached lenses, while cameras without IBIS have to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
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 Olympus PEN E-PM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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 E-PM1 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 hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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, please note that some of the review sites have changed their methodology and reporting over time.
Olympus E-PM1 FAQ
Below are some additional questions and answers concerning some particular features of the E-PM1.
What is the technology behind the imaging sensor in the E-PM1?
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?
Olympus equipped the E-PM1 with the TruePic VI image processor.
What is the ISO sensitivity range of the E-PM1?
The camera has a native sensitivity range from ISO 100 to ISO 12800.
Can the camera be equipped with an optional viewfinder?
Yes, Olympus provides the VF-2 as an accessory (here on amazon) that can be mounted on the hotshoe.
What is the life expectancy of the shutter in the Olympus PEN E-PM1?
Olympus does not publish a shutter rating for the E-PM1. 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.
How do I find the shutter count on my E-PM1?
Olympus embeds the number of shutter actuations in hidden menus. You can check the number of shots that your E-PM1 has taken up to now by carefully following the steps described on the Olympus E-PM1 shutter count page.
Does the Olympus E-PM1 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 E-PM1's flash sync speed is 1/160 sec.
Which battery does the E-PM1 use?
