The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The OM System OM-5 was launched in the US market at a price of $1,199. 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 imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.
The OM System OM-5 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 OM System OM-5 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 alternatives.

Many modern cameras cannot only take still pictures, but also record videos. The OM-5 indeed provides movie recording capabilities. The highest resolution format that the OM-5 can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the OM-5 has an electronic viewfinder with a resolution of 2360k dots. The viewfinder offers a field of view of 100% and a magnification of 0.68x. The adjacent tables list some of the other core features of the OM System OM-5 along with similar information for a selection of comparators.

The LCD screen on the OM System OM-5 is flexibly attached to the body. In particular, the LCD is hinged on the side and can be flipped out for odd-angle shots in both portrait and landscape orientation. Also, this fully articulated, swivel type of LCD attachment is often appreciated by videographers for its flexibility. Moreover, v-loggers like the design because the screen can be turned to be front-facing.
One feature that differentiates the OM-5 from many older cameras is in-body image stabilization (IBIS). The OM-5 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 OM System OM-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the OM-5 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 specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the OM-5 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

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. 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.
OM System OM-5 FAQ
Below are some additional questions and answers concerning some particular features of the OM-5.
What is the technology behind the imaging sensor in the OM-5?
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?
OM System equipped the OM-5 with the TruePic IX image processor.
What is the ISO sensitivity range of the OM-5?
The camera has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600.
Does the camera have a selfie-friendly screen?
Yes, the LCD-screen of the OM-5 is flexible and can be turned to be front-facing for capturing selfies.
What is the life expectancy of the shutter in the OM System OM-5?
OM System does not publish a shutter rating for the OM-5. 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 OM System OM-5?
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 OM System OM-5 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 OM System OM-5?
The OM-5 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 OM System OM-5 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 OM-5's flash sync speed is 1/250 sec.
Does the OM System OM-5 support the Ultra High Speed (UHS) bus interface for SD cards?
Yes, the camera can indeed use UHS-II cards (data transfer speed of up to 312 MB/s).
Which battery does the OM-5 use?
