Nikon D800 vs Olympus E-M1

The Nikon D800 and the Olympus OM-D E-M1 are two digital cameras that were officially introduced, respectively, in February 2012 and September 2013. The D800 is a DSLR, while the E-M1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D800) and a Four Thirds (E-M1) 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-M1? 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 physical size and weight of the Nikon D800 and the Olympus E-M1 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 size dimensions are rounded to the nearest millimeter.

The E-M1 can be obtained in two different colors (black, silver), while the D800 is only available in black.

Size Nikon D800 vs Olympus E-M1
Compare D800 versus E-M1 top
Comparison D800 or E-M1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M1 is considerably smaller (32 percent) than the Nikon D800. Moreover, the E-M1 is substantially lighter (50 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-M1). Mirrorless cameras, such as the E-M1, 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-M1 can take 350 images on a single charge of its BLN-1 power pack.

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

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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-M1 was launched at a markedly lower price (by 53 percent) than the D800, 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.

Sensor comparison

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 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D800 features a full frame sensor and the Olympus E-M1 a Four Thirds sensor. The sensor area in the E-M1 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-M1 offers a 4:3 aspect.

Nikon D800 and Olympus E-M1 sensor measures

With 36.2MP, the D800 offers a higher resolution than the E-M1 (15.9MP), but the D800 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.76μm for the E-M1) due to its larger sensor. However, the E-M1 is a somewhat more recent model (by 1 year and 7 months) than the D800, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

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-M1 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 E-M1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

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-M1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

D800 versus E-M1 MP

Consistent information on actual sensor performance is available from DXO Mark for many 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"). Of the two cameras under review, the D800 provides substantially higher image quality than the E-M1, with an overall score that is 22 points higher. This advantage is based on 2.3 bits higher color depth, 1.7 EV in additional dynamic range, and 1.9 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M1 has an electronic viewfinder (2360k 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 E-M1 has a higher magnification than the one of the D800 (0.74x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D800 and Olympus E-M1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D800 has one, while the E-M1 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 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 E-M1 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 D800 and the Olympus E-M1 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 D800 writes its imaging data to Compact Flash or SDXC cards, while the E-M1 uses SDXC cards. The D800 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M1 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.

Connectivity 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 Nikon D800 and Olympus OM-D E-M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D800 has a headphone jack, which is not present on the E-M1 This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the D800 and the E-M1 have been discontinued, but can regularly be found used on eBay. The D800 was replaced by the Nikon D810, while the E-M1 was followed by the Olympus E-M1 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.

Review summary

So how do things add up? Is the Nikon D800 better than the Olympus E-M1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Olympus OM-D E-M1:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.70x).
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 921k dots).
  • 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 (10 vs 4 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (130x94mm vs 146x123mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 503g or 50 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.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 7 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M1 comes out slightly ahead of the D800 (16 : 15 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

D800 15:16 E-M1

How about other alternatives? Do the specifications of the Nikon D800 and the Olympus E-M1 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 D800 or the E-M1 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.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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

The above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
