Nikon D800 vs Olympus E-M5

The Nikon D800 and the Olympus OM-D E-M5 are two digital cameras that were officially introduced in February 2012. The D800 is a DSLR, while the E-M5 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D800) and a Four Thirds (E-M5) sensor. The Nikon has a resolution of 36.2 megapixels, whereas the Olympus provides 15.9 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 D800 and the Olympus OM-D E-M5? 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Nikon D800 and the Olympus E-M5. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The E-M5 can be obtained in two different colors (black, silver), while the D800 is only available in black.

Size Nikon D800 vs Olympus E-M5
Compare D800 versus E-M5 top
Comparison D800 or E-M5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M5 is considerably smaller (40 percent) than the Nikon D800. Moreover, the E-M5 is substantially lighter (58 percent) than the D800. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 (D800) and the Micro Four Thirds Lens Catalog (E-M5). Mirrorless cameras, such as the E-M5, 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 D800 gets 900 shots out of its EN-EL15 battery, while the E-M5 can take 360 images on a single charge of its BLN-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-M5 was launched at a markedly lower price (by 57 percent) than the D800, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D800 features a full frame sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 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 D800 has a native 3:2 aspect ratio, while the one in the E-M5 offers a 4:3 aspect.

In terms of underlying technology, both cameras are build around CMOS sensors.

Nikon D800 and Olympus E-M5 sensor measures

With 36.2MP, the D800 offers a higher resolution than the E-M5 (15.9MP), but the D800 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.76μm for the E-M5) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The resolution advantage of the Nikon D800 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D800 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Olympus E-M5 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The Nikon D800 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Olympus OM-D E-M5 are ISO 200 to ISO 25600 (no boost).

D800 versus E-M5 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 D800 provides substantially higher image quality than the E-M5, with an overall score that is 24 points higher. This advantage is based on 2.5 bits higher color depth, 2.1 EV in additional dynamic range, and 1.8 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-M5 provides a faster frame rate than the D800. It can shoot movie footage at 1080/60i, while the Nikon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M5 has an electronic viewfinder (1440k dots), while the D800 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D800 has a higher magnification than the one of the E-M5 (0.70x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D800 and Olympus E-M5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D800 has one, while the E-M5 does not. While the built-in flash of the D800 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D800 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 D800 writes its imaging data to Compact Flash or SDXC cards, while the E-M5 uses SDXC cards. The D800 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the D800 has a microphone port, which is missing on the E-M5. 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 D800 (unlike the E-M5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D800 and the E-M5 have been discontinued, but can regularly be found used on eBay. The D800 was replaced by the Nikon D810, while the E-M5 was followed by the Olympus E-M5 II. 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.

  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (9 vs 4 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (122x89mm vs 146x123mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 575g or 57 percent) and is thus easier to take along.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).

If the number of relative strengths (bullet points above) is taken as a guide, the D800 is the clear winner of the match-up (19 : 10 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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.

D800 19:10 E-M5

How about other alternatives? Do the specifications of the Nikon D800 and the Olympus E-M5 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D800 or the E-M5. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price 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.
