Nikon Coolpix A vs Olympus E-PM2
The Nikon Coolpix A and the Olympus PEN E-PM2 are two digital cameras that were officially introduced, respectively, in March 2013 and September 2012. The Coolpix A is a fixed lens compact, while the E-PM2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (Coolpix A) 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 Coolpix A 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.
The side-by-side display below illustrates the physical size and weight of the Nikon Coolpix A and the Olympus E-PM2. 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 Coolpix A can be obtained in two different colors (black, silver), while the E-PM2 is available in four color-versions (black, silver, red, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Coolpix A and the Olympus E-PM2 are of equal size. In this context, it is worth noting that neither the Coolpix A nor the E-PM2 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Coolpix A has a lens built in, whereas the E-PM2 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-PM2 and their specifications in the Micro Four Thirds Lens Catalog.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 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 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon Coolpix A 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 Coolpix A has a native 3:2 aspect ratio, while the one in the E-PM2 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 16.1MP, the Coolpix A offers a slightly higher resolution than the E-PM2 (15.9MP), but the Coolpix A nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 3.76μm for the E-PM2) due to its larger sensor. Moreover, the Coolpix A is a somewhat more recent model (by 5 months) than the E-PM2, 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 Coolpix A has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Nikon Coolpix A 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).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the Coolpix A 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 0.7 bits higher color depth, 1.6 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.
|Nikon Coolpix A||APS-C||16.1||4928||3264||1080/30p||23.4||13.8||1164||80|

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. The Coolpix A and the E-PM2 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the DF-CP1 for the Coolpix A and the VF-4 for the E-PM2 – are available as accessories. The table below summarizes some of the other core capabilities of the Nikon Coolpix A and Olympus E-PM2 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 Coolpix A has one, while the E-PM2 does not. While the built-in flash of the Coolpix A is not very powerful, it can at times be useful as a fill-in light.
The Nikon Coolpix A 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 Coolpix A and the E-PM2 write their files to SDXC cards. The E-PM2 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Coolpix A cannot take advantage of Ultra High Speed SD cards.
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 Coolpix A and Olympus PEN E-PM2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the Coolpix A and the E-PM2 have been discontinued, but can regularly be found used on eBay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Nikon and Olympus. 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 Coolpix A better than the Olympus E-PM2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Nikon Coolpix A:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- 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 (1.6 EV of extra DR).
- More detailed LCD: Has a higher resolution rear screen (921k vs 460k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has a lens built-in, whereas the E-PM2 requires a separate lens.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More modern: Is somewhat more recent (announced 5 months after the E-PM2).
Advantages of the Olympus PEN E-PM2:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (8 vs 4 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (360 versus 230) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been on the market for longer (launched in September 2012).
If the count of relative strengths (bullet points above) is taken as a measure, the E-PM2 comes out slightly ahead of the Coolpix A (9 : 8 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Coolpix A and the Olympus E-PM2 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact 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 says little about, for example, the shooting experience and imaging performance of the Coolpix A and the E-PM2 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
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 (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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
