Nikon D810 versus Olympus PEN-F
The Nikon D810 and the Olympus PEN-F are two digital cameras that were revealed to the public, respectively, in June 2014 and January 2016. The D810 is a DSLR, while the PEN-F is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D810) and a Four Thirds sensor. The Nikon has a resolution of 36.2 megapixel, whereas the Olympus provides 20.2 MP.
The side-by-side display below illustrates the physical size and weight of the Nikon D810 and the Olympus PEN-F. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the D810 – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus PEN-F is considerably smaller (50 percent) than the Nikon D810. Moreover, the PEN-F is substantially lighter (56 percent) than the D810. It is worth mentioning in this context that the D810 is splash and dust resistant, while the PEN-F 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 find an overview of optics for the two cameras in the Nikon Lens Catalog (D810) and the Micro Four Thirds Lens Catalog (PEN-F). Mirrorless cameras, such as the PEN-F, 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The PEN-F was launched at a markedly lower price (by 64 percent) than the D810, 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 sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D810 features a full frame sensor and the Olympus PEN-F a Four Thirds sensor. The sensor area in the PEN-F 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 D810 has a native 3:2 aspect ratio, while the one in the PEN-F offers a 4:3 aspect.
With 36.2MP, the D810 offers a higher resolution than the PEN-F (20.2MP), but the D810 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 3.34μm for the PEN-F) due to its larger sensor. However, the PEN-F is a somewhat more recent model (by 1 year and 7 months) than the D810, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
Unlike the D810, the PEN-F has the capacity to capture high quality composite images (40MP) 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).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 D810 provides substantially higher image quality than the PEN-F, with an overall score that is 23 points higher. This advantage is based on 2.6 bits higher color depth, 2.4 EV in additional dynamic range, and 1.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the PEN-F has an electronic viewfinder (2360k dots), while the D810 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 table below summarizes some of the other core capabilities of the Nikon D810 and Olympus PEN-F in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The PEN-F is a current model that online retailers, such as amazon, will have in stock. In contrast, the D810 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the D810 was succeeded by the Nikon D850.
So what conclusions can be drawn? Is the Nikon D810 better than the Olympus PEN-F or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Nikon D810:
- More detail: Offers more megapixels (36.2 vs 20.2MP) with a 37% higher linear resolution.
- Better image quality: Scores substantially higher (23 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.6 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.4 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.7 stops ISO advantage).
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Has an LCD display on top to control shooting parameters.

If the count of individual advantages (bullet points above) is taken as a guide, the D810 comes out slightly ahead of the PEN-F (13 : 12 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the D810 or the PEN-F. 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 table below summarizes the assessments of some of the best known camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
