The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The OM System OM-1 was launched in the US market at a price of $2,199. 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-1 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-1 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

OM System OM-1 sensor measures

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 can also record movies. The OM-1 indeed provides movie recording capabilities. The highest resolution format that the OM-1 can use is 4K/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the OM-1 has an electronic viewfinder with a resolution of 5760k dots. The viewfinder offers a field of view of 100% and a magnification of 0.82x. The following tables report on some other key feature differences and similarities of the OM System OM-1 and comparable cameras.

The LCD screen on the OM System OM-1 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-1 from many older cameras is in-body image stabilization (IBIS). The OM-1 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.

It is notable that the OM-1 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.

Further information on the features and operation of the OM-1 can be found in the free online OM System OM-1 Manual or on the OM System support site.

Expert reviews

While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the OM-1. 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.

OM System OM-1 FAQ

Below are some additional questions and answers concerning some particular features of the OM-1.

What is the technology behind the imaging sensor in the OM System OM-1?

The camera is build around a Stacked BSI-CMOS (Stacked Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensor.

Which image processing chip is used in the OM System OM-1 to convert the raw signal into an image file and perform noise reduction and image sharpening?

OM System equipped the OM-1 with the TruePic X image processor.

What is the ISO sensitivity range of the OM System OM-1?

The camera has a native sensitivity range from ISO 80 to ISO 25600.

Does the OM System OM-1 have a selfie-friendly screen?

Yes, the LCD-screen of the OM-1 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-1?

OM System mentions a shutter rating of 400 000 actuations for the OM-1. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the OM-1 over, say, three years, one would have to take about 400 pictures each and every day.

How do I find the shutter count on my OM System OM-1?

OM System embeds the number of shutter actuations in hidden menus. You can check the number of shots that your OM-1 has taken up to now by carefully following the steps described on the OM System OM-1 shutter count page.

Is completely silent shooting possible with the OM System OM-1?

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 with the OM System OM-1?

No, the OM System OM-1 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-1?

The OM-1 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-1 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 the OM System OM-1 for flash photography?

The OM-1's flash sync speed is 1/250 sec.

Does the OM System OM-1 support the Ultra High Speed (UHS) bus interface for SD cards?

Yes, the camera can indeed use UHS-II cards, which provide for data transfer speed of up to 312 MB/s, in both of its card slots.

Which battery does the OM System OM-1 use?

The camera gets its power from the OM System BLX-1 (here at amazon), which is a rechargeable Lithium-Ion power pack.

Is there a vertical grip available for the OM System OM-1?

Yes, OM System offers the HLD-10 as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.

Where can I find the best deals for the OM System OM-1?

Grey imports from Asia, as found on ebay, are often very attractively priced. However, these cameras come without a warranty from OM System.
