The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The OM System OM-5 II 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 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

The OM System OM-5 II 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 II among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

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.

Many modern cameras cannot only take still pictures, but also record videos. The OM-5 II indeed provides movie recording capabilities. The highest resolution format that the OM-5 II 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 OM-5 II 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 II along with similar information for a selection of comparators.

The LCD screen on the OM System OM-5 II 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 II from many older cameras is in-body image stabilization (IBIS). The OM-5 II 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.

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 OM System OM-5 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the OM-5 II 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 says nothing about, for example, the handling, responsiveness, and overall imaging quality of the OM-5 II 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 table below summarizes the assessments of some of the best known 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
