Nikon D5000 vs OM System OM-1

The Nikon D5000 and the OM System OM-1 are two digital cameras that were revealed to the public, respectively, in April 2009 and February 2022. The D5000 is a DSLR, while the OM-1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D5000) and a Four Thirds (OM-1) sensor. The Nikon has a resolution of 12.2 megapixels, whereas the OM System provides 20.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The physical size and weight of the Nikon D5000 and the OM System OM-1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Nikon D5000 vs OM System OM-1
Compare D5000 versus OM-1 top
Comparison D5000 or OM-1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the OM System OM-1 is notably smaller (6 percent) than the Nikon D5000. However, the OM-1 is slightly heavier (2 percent) than the D5000. It is noteworthy in this context that the OM-1 is splash and dust-proof, while the D5000 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D5000) and the Micro Four Thirds Lens Catalog (OM-1). Mirrorless cameras, such as the OM-1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the D5000 gets 510 shots out of its Nikon EN-EL9a battery, while the OM-1 can take 520 images on a single charge of its OM System BLX-1 power pack. The power pack in the OM-1 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D5000 was launched at a markedly lower price (by 66 percent) than the OM-1, which puts it into a different market segment. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D5000 features an APS-C sensor and the OM System OM-1 a Four Thirds sensor. The sensor area in the OM-1 is 40 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D5000 has a native 3:2 aspect ratio, while the one in the OM-1 offers a 4:3 aspect.

Nikon D5000 and OM System OM-1 sensor measures

Despite having a smaller sensor, the OM-1 offers a higher resolution of 20.2 megapixels, compared with 12.2 MP of the D5000. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 5.53μm for the D5000). However, it should be noted that the OM-1 is much more recent (by 12 years and 10 months) than the D5000, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the OM-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the OM System OM-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the OM-1 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Nikon D5000 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The OM-1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the D5000, the OM-1 has the capacity to capture high quality composite images (80MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Nikon D5000 has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 200-6400. The corresponding ISO settings for the OM System OM-1 are ISO 80 to ISO 25600, with the possibility to increase the ISO range to 80-102400.

In terms of underlying technology, the D5000 is build around a CMOS sensor, while the OM-1 uses a Stacked BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

D5000 versus OM-1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the OM-1 provides a better video resolution than the D5000. It can shoot movie footage at 4K/60p, while the Nikon is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the OM-1 has an electronic viewfinder (5760k dots), while the D5000 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the OM-1 offers a wider field of view (100%) than the one in the D5000 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the OM-1 has a higher magnification (0.82x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D5000, the OM System OM-1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D5000 has one, while the OM-1 does not. While the built-in flash of the D5000 is not very powerful, it can at times be useful as a fill-in light.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the OM-1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Nikon D5000 and the OM System OM-1 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The D5000 writes its imaging data to SDHC cards, while the OM-1 uses SDXC cards. The OM-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D5000 only has one slot. The OM-1 supports UHS-II cards (on both slots), while the D5000 cannot take advantage of Ultra High Speed SD cards.

It is notable that the OM-1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D5000 does not provide wifi capability.

Studio photographers will appreciate that the OM System OM-1 (unlike the D5000) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D5000 and the OM-1 have been discontinued, but can regularly be found used on ebay. The D5000 was replaced by the Nikon D5100, while the OM-1 was followed by the OM System OM-1 II. Further information on the features and operation of the D5000 and OM-1 can be found, respectively, in the Nikon D5000 Manual (free pdf) or the online OM System OM-1 Manual.

  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards on both slots.
  • More modern: Reflects 12 years and 10 months of technical progress since the D5000 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the OM-1 is the clear winner of the contest (27 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

D5000 05:27 OM-1

How about other alternatives? Do the specifications of the Nikon D5000 and the OM System OM-1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D5000 or the OM-1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The adjacent summary-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]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
