Nikon D780 vs Olympus E-M5 III
The Nikon D780 and the Olympus OM-D E-M5 Mark III are two enthusiast cameras that were revealed to the public, respectively, in January 2020 and October 2019. The D780 is a DSLR, while the E-M5 III is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D780) and a Four Thirds (E-M5 III) sensor. The Nikon has a resolution of 24.3 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 D780 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.
The physical size and weight of the Nikon D780 and the Olympus E-M5 III are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.
The E-M5 III can be obtained in two different colors (black, silver), while the D780 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-M5 III is considerably smaller (36 percent) than the Nikon D780. Moreover, the E-M5 III is substantially lighter (51 percent) than the D780. 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 (D780) 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 D780 gets 2260 shots out of its EN-EL15b battery, while the E-M5 III can take 310 images on a single charge of its BLS-50 power pack. The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 III was launched at a markedly lower price (by 48 percent) than the D780, 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.
The size of the imaging sensor is a crucial determinant 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. 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 D780 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 D780 has a native 3:2 aspect ratio, while the one in the E-M5 III offers a 4:3 aspect.
With 24.3MP, the D780 offers a higher resolution than the E-M5 III (20.2MP), but the D780 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.34μm for the E-M5 III) 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. 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 resolution advantage of the Nikon D780 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D780 for good quality output (200 dots per inch) amounts to 30.2 x 20.1 inches or 76.8 x 51.1 cm, for very good quality (250 dpi) 24.2 x 16.1 inches or 61.4 x 40.9 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inches or 51.2 x 34.1 cm. The corresponding values for the Olympus E-M5 III are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 cm for excellent quality prints.
Unlike the D780, 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 D780 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-204800. 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.
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"). 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 have a sensor with sufficiently fast read-out times for moving pictures, but the D780 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/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M5 III has an electronic viewfinder (2360k dots), while the D780 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 D780 has a higher magnification than the one of the E-M5 III (0.70x vs 0.68x), 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 D780 and Olympus E-M5 III in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D780, 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 D780 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 D780 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.
Concerning the storage of imaging data, both the D780 and the E-M5 III write their files to SDXC cards. The D780 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. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.
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 D780 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 D780 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.
Studio photographers will appreciate that the Nikon D780 (unlike the E-M5 III) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D780 and the E-M5 III are recent models that are part of the current product line-up. The E-M5 III replaced the earlier Olympus E-M5 II, while the D780 followed on from the Nikon D750. 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.
So what conclusions can be drawn? Is the Nikon D780 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.

- More affordable: Was introduced into a lower priced category (48 percent cheaper at launch).
If the number of relative strengths (bullet points above) is taken as a guide, the D780 is the clear winner of the match-up (18 : 11 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 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.
How about other alternatives? Do the specifications of the Nikon D780 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the D780 and the E-M5 III in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
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], 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 ratings are only valid when referring to cameras in the same category and of the same age. 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.
