Nikon D5 vs Olympus E-PM1
The Nikon D5 and the Olympus PEN E-PM1 are two digital cameras that were revealed to the public, respectively, in January 2016 and June 2011. The D5 is a DSLR, while the E-PM1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D5) and a Four Thirds (E-PM1) sensor. The Nikon has a resolution of 20.7 megapixels, whereas the Olympus provides 12.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D5 and the Olympus PEN E-PM1? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Nikon D5 and the Olympus E-PM1. 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 dimensions are rounded to the nearest millimeter.
The E-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, white), while the D5 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PM1 is considerably smaller (72 percent) than the Nikon D5. Moreover, the E-PM1 is substantially lighter (81 percent) than the D5. It is worth mentioning in this context that the D5 is splash and dust resistant, while the E-PM1 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 (D5) and the Micro Four Thirds Lens Catalog (E-PM1). Mirrorless cameras, such as the E-PM1, 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 D5 gets 3780 shots out of its EN-EL18a battery, while the E-PM1 can take 330 images on a single charge of its BLS-5 power pack. As can be seen in the images above, the D5 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-PM1 was launched at a markedly lower price (by 92 percent) than the D5, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D5 features a full frame sensor and the Olympus E-PM1 a Four Thirds sensor. The sensor area in the E-PM1 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the D5 has a native 3:2 aspect ratio, while the one in the E-PM1 offers a 4:3 aspect.
With 20.7MP, the D5 offers a higher resolution than the E-PM1 (12.2MP), but the D5 nevertheless has larger individual pixels (pixel pitch of 6.44μm versus 4.29μm for the E-PM1) due to its larger sensor. Moreover, the D5 is a much more recent model (by 4 years and 6 months) than the E-PM1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Nikon D5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D5 for good quality output (200 dots per inch) amounts to 27.9 x 18.6 inches or 71 x 47.1 cm, for very good quality (250 dpi) 22.4 x 14.8 inches or 56.8 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.3 x 31.4 cm. The corresponding values for the Olympus E-PM1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Nikon D5 has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-3280000. The corresponding ISO settings for the Olympus PEN E-PM1 are ISO 100 to ISO 12800 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many 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. Of the two cameras under review, the D5 provides substantially higher image quality than the E-PM1, with an overall score that is 36 points higher. This advantage is based on 4.1 bits higher color depth, 2 EV in additional dynamic range, and 2.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the D5 provides a higher video resolution than the E-PM1. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D5 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PM1 relies on live view and the rear LCD for framing. That said, the E-PM1 can be equipped with an optional viewfinder – the VF-2. The following table reports on some other key feature differences and similarities of the Nikon D5, the Olympus E-PM1, and comparable cameras.

One feature that is present on the D5, but is missing on the E-PM1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The Nikon D5 has 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 D5 writes its imaging data to Compact Flash or XQD cards, while the E-PM1 uses SDXC cards. The D5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PM1 only has one slot.
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 Nikon D5 and Olympus PEN E-PM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D5 has a microphone port, which is missing on the E-PM1. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Nikon D5 (unlike the E-PM1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D5 and the E-PM1 have been discontinued, but can regularly be found used on eBay. The E-PM1 was replaced by the Olympus E-PM2, while the D5 was followed by the Nikon D6. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Olympus websites.

If the count of individual advantages (bullet points above) is taken as a guide, the D5 is the clear winner of the match-up (23 : 6 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.
How about other alternatives? Do the specifications of the Nikon D5 and the Olympus E-PM1 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the D5 or the E-PM1 perform in practice. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 review scores listed above should be treated with care, 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
