Nikon D7100 vs Olympus E-M5
The Nikon D7100 and the Olympus OM-D E-M5 are two enthusiast cameras that were officially introduced, respectively, in February 2013 and February 2012. The D7100 is a DSLR, while the E-M5 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D7100) and a Four Thirds (E-M5) sensor. The Nikon has a resolution of 24 megapixels, whereas the Olympus provides 15.9 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 D7100 and the Olympus OM-D E-M5? 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: Nikon D7100 vs Olympus E-M5
The side-by-side display below illustrates the physical size and weight of the Nikon D7100 and the Olympus E-M5. 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 size dimensions are rounded to the nearest millimeter.
The E-M5 can be obtained in two different colors (black, silver), while the D7100 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 is notably smaller (25 percent) than the Nikon D7100. Moreover, the E-M5 is substantially lighter (44 percent) than the D7100. 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 (D7100) and the Micro Four Thirds Lens Catalog (E-M5). Mirrorless cameras, such as the E-M5, 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.

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 D7100 was somewhat cheaper (by 8 percent) than the E-M5 at launch, but both cameras fall into the same price category. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Nikon D7100 vs Olympus E-M5
The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D7100 features an APS-C sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 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 D7100 has a native 3:2 aspect ratio, while the one in the E-M5 offers a 4:3 aspect.
With 24MP, the D7100 offers a higher resolution than the E-M5 (15.9MP), but the D7100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.76μm for the E-M5) due to its larger sensor. Moreover, the D7100 is a somewhat more recent model (by 1 year) than the E-M5, and its sensor might 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 D7100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D7100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7100 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Olympus E-M5 are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.
The Nikon D7100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Olympus OM-D E-M5 are ISO 200 to ISO 25600 (no boost).
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. Of the two cameras under review, the D7100 provides substantially higher image quality than the E-M5, with an overall score that is 12 points higher. This advantage is based on 1.4 bits higher color depth, 1.4 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D7100 provides a higher frame rate than the E-M5. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/60i.
Feature comparison: Nikon D7100 vs Olympus E-M5
Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M5 has an electronic viewfinder (1440k dots), while the D7100 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 D7100 has a higher magnification than the one of the E-M5 (0.63x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D7100 and Olympus E-M5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D7100 has one, while the E-M5 does not. While the built-in flash of the D7100 is not very powerful, it can at times be useful as a fill-in light.
The Nikon D7100 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.
Concerning the storage of imaging data, both the D7100 and the E-M5 write their files to SDXC cards. The D7100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
Connectivity comparison: Nikon D7100 vs Olympus E-M5
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 D7100 and Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D7100 has a microphone port, which is missing on the E-M5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the D7100 and the E-M5 have been discontinued, but can regularly be found used on eBay. The E-M5 was replaced by the Olympus E-M5 II, while the D7100 was followed by the Nikon D7200. 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.

If the number of relative strengths (bullet points above) is taken as a guide, the D7100 is the clear winner of the match-up (20 : 10 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 D7100 and the Olympus E-M5 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 D7100 or the E-M5. 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: Nikon D7100 vs Olympus E-M5
This is why expert reviews 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.|
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. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
