Body comparison

The side-by-side display below illustrates the physical size and weight of the Nikon D780 and the Olympus E-P7. 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-P7 can be obtained in three different colors (black, silver, white), while the D780 is only available in black.

Size Nikon D780 vs Olympus E-P7
Compare D780 versus E-P7 top
Comparison D780 or E-P7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P7 is considerably smaller (51 percent) than the Nikon D780. Moreover, the E-P7 is substantially lighter (60 percent) than the D780. It is worth mentioning in this context that the D780 is splash and dust resistant, while the E-P7 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 (D780) and the Micro Four Thirds Lens Catalog (E-P7). Mirrorless cameras, such as the E-P7, 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 Nikon EN-EL15b battery, while the E-P7 can take 360 images on a single charge of its Olympus BLS-50 power pack. The power pack in the D780 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-P7 was launched at a markedly lower price (by 65 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D780 features a full frame sensor and the Olympus E-P7 a Four Thirds sensor. The sensor area in the E-P7 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-P7 offers a 4:3 aspect.

Nikon D780 and Olympus E-P7 sensor measures

With 24.3MP, the D780 offers a higher resolution than the E-P7 (20.2MP), but the D780 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 3.34μm for the E-P7) due to its larger sensor. However, the E-P7 is a somewhat more recent model (by 1 year and 5 months) than the D780, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

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-P7 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.

The D780 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

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 PEN E-P7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the D780 is build around a BSI-CMOS sensor, while the E-P7 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

D780 versus E-P7 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").

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D780 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P7 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Nikon D780, the Olympus E-P7, and comparable cameras.

One feature that is present on the D780, but is missing on the E-P7 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-P7 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-P7 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-P7 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-P7 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-P7 only has one slot. Both cameras support UHS-II cards, which provide for Ultra High Speed data transfer of up to 312 MB/s.

It is notable that the D780 has a microphone port, which is missing on the E-P7. 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 D780 (unlike the E-P7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D780 and the E-P7 are recent models that are part of the current product line-up. The D780 replaced the earlier Nikon D750, while the E-P7 followed on from the Olympus E-P5. Further information on the features and operation of the D780 and E-P7 can be found, respectively, in the Nikon D780 Manual (free pdf) or the online Olympus E-P7 Manual.

ilogo

Arguments in favor of the Olympus PEN E-P7:

  • 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 (118x69mm vs 144x116mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 503g or 60 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 fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 5 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the D780 is the clear winner of the match-up (21 : 9 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.

D780 21:09 E-P7

How about other alternatives? Do the specifications of the Nikon D780 and the Olympus E-P7 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 D780 or the E-P7. 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.

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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
