Nikon D5 vs Olympus E-M5 III

The Nikon D5 and the Olympus OM-D E-M5 Mark III are two digital cameras that were announced, respectively, in January 2016 and October 2019. The D5 is a DSLR, while the E-M5 III is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D5) and a Four Thirds (E-M5 III) sensor. The Nikon has a resolution of 20.7 megapixels, whereas the Olympus provides 20.2 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 OM-D E-M5 Mark III? 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

An illustration of the physical size and weight of the Nikon D5 and the Olympus E-M5 III is provided 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 dimensions are rounded to the nearest millimeter.

The E-M5 III can be obtained in two different colors (black, silver), while the D5 is only available in black.

Size Nikon D5 vs Olympus E-M5 III
Compare D5 versus E-M5 III top
Comparison D5 or E-M5 III 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 III is considerably smaller (58 percent) than the Nikon D5. Moreover, the E-M5 III is substantially lighter (71 percent) than the D5. 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 (D5) and the Micro Four Thirds Lens Catalog (E-M5 III). Mirrorless cameras, such as the E-M5 III, 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-M5 III can take 310 images on a single charge of its BLS-50 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 power pack in the E-M5 III can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 E-M5 III was launched at a markedly lower price (by 82 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.

 

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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 D5 features a full frame sensor and the Olympus E-M5 III a Four Thirds sensor. The sensor area in the E-M5 III 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-M5 III offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Nikon D5 and Olympus E-M5 III sensor measures

With 20.7MP, the D5 offers a slightly higher resolution than the E-M5 III (20.2MP), but the D5 nevertheless has larger individual pixels (pixel pitch of 6.44μm versus 3.34μm for the E-M5 III) due to its larger sensor. However, the E-M5 III is a much more recent model (by 3 years and 9 months) than the D5, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the E-M5 III has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The E-M5 III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the D5, the E-M5 III 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 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 OM-D E-M5 Mark III are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.

D5 versus E-M5 III MP

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.

Many modern cameras cannot only take still pictures, but also record videos. 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 frame rate than the E-M5 III. It can shoot video footage at 4K/30p, while the Olympus is limited to 4k/24p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M5 III has an electronic viewfinder (2360k dots), while the D5 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 D5 has a higher magnification than the one of the E-M5 III (0.72x vs 0.68x), 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 D5, the Olympus E-M5 III, and comparable cameras.

One feature that is present on the D5, but is missing on the E-M5 III 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 E-M5 III has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D5 does not have a selfie-screen.

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-M5 III 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 D5 and the Olympus E-M5 III 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 D5 writes its imaging data to Compact Flash or XQD cards, while the E-M5 III uses SDXC cards. The D5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 III only has one slot.

 

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 D5 and Olympus OM-D E-M5 Mark III 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 headphone jack, which is not present on the E-M5 III 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.

The E-M5 III is a recent model that features in the current product line-up of Olympus. In contrast, the D5 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D5 was succeeded 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.

Review summary

So how do things add up? Is the Nikon D5 better than the Olympus E-M5 III or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Olympus OM-D E-M5 Mark III:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (125x85mm vs 160x159mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 1001g or 71 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • 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.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M5 III comes out slightly ahead of the D5 (15 : 14 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.

D5 14:15 E-M5 III

How about other alternatives? Do the specifications of the Nikon D5 and the Olympus E-M5 III 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 says little about, for example, the shooting experience and imaging performance of the D5 and the E-M5 III in practical situations. 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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
