Nikon D5100 vs Olympus E-PM2
The Nikon D5100 and the Olympus PEN E-PM2 are two digital cameras that were revealed to the public, respectively, in April 2011 and September 2012. The D5100 is a DSLR, while the E-PM2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D5100) and a Four Thirds (E-PM2) sensor. The Nikon has a resolution of 16.1 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 D5100 and the Olympus PEN E-PM2? 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
The physical size and weight of the Nikon D5100 and the Olympus E-PM2 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The E-PM2 can be obtained in four different colors (black, silver, red, white), while the D5100 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-PM2 is considerably smaller (43 percent) than the Nikon D5100. Moreover, the E-PM2 is substantially lighter (52 percent) than the D5100. In this context, it is worth noting that neither the D5100 nor the E-PM2 are weather-sealed.
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 (D5100) and the Micro Four Thirds Lens Catalog (E-PM2). Mirrorless cameras, such as the E-PM2, 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 D5100 gets 660 shots out of its Nikon EN-EL14 battery, while the E-PM2 can take 360 images on a single charge of its Olympus BLS-5 power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

Any camera decision will obviously take relative prices into account. 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-PM2 was launched at a markedly lower price (by 33 percent) than the D5100, 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.
Sensor comparison
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 D5100 features an APS-C sensor and the Olympus E-PM2 a Four Thirds sensor. The sensor area in the E-PM2 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 D5100 has a native 3:2 aspect ratio, while the one in the E-PM2 offers a 4:3 aspect.
With 16.1MP, the D5100 offers a slightly higher resolution than the E-PM2 (15.9MP), but the D5100 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the E-PM2) due to its larger sensor. However, the E-PM2 is a somewhat more recent model (by 1 year and 5 months) than the D5100, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The Nikon D5100 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus PEN E-PM2 are ISO 100 to ISO 25600 (no boost).
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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 D5100 has a notably higher overall DXO score than the E-PM2 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 1.4 EV in additional dynamic range, and 0.3 stops in additional low light sensitivity. 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 can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D5100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PM2 relies on live view and the rear LCD for framing. That said, the E-PM2 can be equipped with an optional viewfinder – the VF-4. The following table reports on some other key feature differences and similarities of the Nikon D5100, the Olympus E-PM2, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D5100 has one, while the E-PM2 does not. While the built-in flash of the D5100 is not very powerful, it can at times be useful as a fill-in light.
The D5100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-PM2 does not have a selfie-screen.The Nikon D5100 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 D5100 and the E-PM2 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
Connectivity comparison
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 D5100 and Olympus PEN E-PM2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D5100 has a microphone port, which is missing on the E-PM2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the D5100 and the E-PM2 have been discontinued, but can regularly be found used on ebay. The D5100 was replaced by the Nikon D5200, while the E-PM2 does not have a direct successor. Further information on the features and operation of the D5100 and E-PM2 can be found, respectively, in the Nikon D5100 Manual (free pdf) or the online Olympus E-PM2 Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Nikon D5100 or the Olympus E-PM2 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Nikon D5100:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.4 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (921k vs 460k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (660 versus 360) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been on the market for longer (launched in April 2011).
Arguments in favor of the Olympus PEN E-PM2:
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (8 vs 4 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (110x64mm vs 128x97mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 291g or 52 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.
- More affordable: Was introduced into a lower priced category (33 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 D5100 is the clear winner of the match-up (12 : 8 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 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 D5100 and the Olympus E-PM2 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 D5100 or the E-PM2. 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.
Expert reviews
This is why expert reviews 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
