Nikon D100 vs Olympus E-M1 II
The Nikon D100 and the Olympus OM-D E-M1 Mark II are two enthusiast cameras that were announced, respectively, in February 2002 and September 2016. The D100 is a DSLR, while the E-M1 II is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D100) and a Four Thirds (E-M1 II) sensor. The Nikon has a resolution of 6 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 D100 and the Olympus OM-D E-M1 Mark II? 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 D100 and the Olympus E-M1 II 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 width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M1 II is notably smaller (27 percent) than the Nikon D100. Moreover, the E-M1 II is markedly lighter (26 percent) than the D100. It is noteworthy in this context that the E-M1 II is splash and dust-proof, while the D100 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 (D100) and the Micro Four Thirds Lens Catalog (E-M1 II). Mirrorless cameras, such as the E-M1 II, 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 two cameras under review were launched at the same price and fall into the same 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.
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 D100 features an APS-C sensor and the Olympus E-M1 II a Four Thirds sensor. The sensor area in the E-M1 II is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D100 has a native 3:2 aspect ratio, while the one in the E-M1 II offers a 4:3 aspect.
Despite having a smaller sensor, the E-M1 II offers a higher resolution of 20.2 megapixels, compared with 6 MP of the D100. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 7.85μm for the D100). However, it should be noted that the E-M1 II is much more recent (by 14 years and 7 months) than the D100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the E-M1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Olympus E-M1 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M1 II for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Nikon D100 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.
The E-M1 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
Unlike the D100, the E-M1 II has the capacity to capture high quality composite images (50MP) 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 D100 has a native sensitivity range from ISO 200 to ISO 800, which can be extended to ISO 200-1600. The corresponding ISO settings for the Olympus OM-D E-M1 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 64-25600.
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. 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 are not only capable of taking still images, but also of capturing video footage. The E-M1 II indeed provides for movie recording, while the D100 does not. The highest resolution format that the E-M1 II can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M1 II has an electronic viewfinder (2360k dots), while the D100 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 viewfinder in the E-M1 II offers a wider field of view (100%) than the one in the D100 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M1 II has a higher magnification (0.74x vs 0.53x), 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 D100 and Olympus E-M1 II 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 D100 has one, while the E-M1 II does not. While the built-in flash of the D100 is not very powerful, it can at times be useful as a fill-in light.The E-M1 II 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 D100 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-M1 II 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 Olympus E-M1 II has 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 D100 writes its imaging data to Compact Flash cards, while the E-M1 II uses SDXC cards. The E-M1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the D100 only has one slot.
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 D100 and Olympus OM-D E-M1 Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M1 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D100 does not provide wifi capability.
Studio photographers will appreciate that the Olympus E-M1 II (unlike the D100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The E-M1 II is a recent model that features in the current product line-up of Olympus. In contrast, the D100 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D100 was succeeded by the Nikon D200. 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 D100 better than the Olympus E-M1 II or vice versa? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M1 II is the clear winner of the contest (28 : 5 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.
How about other alternatives? Do the specifications of the Nikon D100 and the Olympus E-M1 II 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D100 or the E-M1 II. 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.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera 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 are only valid when referring to cameras in the same category and of the same age. 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.
