Nikon Coolpix A vs Olympus E-P2
The Nikon Coolpix A and the Olympus PEN E-P2 are two enthusiast cameras that were officially introduced, respectively, in March 2013 and November 2009. The Coolpix A is a fixed lens compact, while the E-P2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (Coolpix A) and a Four Thirds (E-P2) sensor. The Nikon has a resolution of 16.1 megapixels, whereas the Olympus provides 12.2 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 Coolpix A and the Olympus PEN E-P2? 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.
An illustration of the physical size and weight of the Nikon Coolpix A and the Olympus E-P2 is provided 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 dimensions are rounded to the nearest millimeter.
The Coolpix A can be obtained in two different colors (black, silver), while the E-P2 is available in three color-versions (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P2 is notably larger (19 percent) than the Nikon Coolpix A. In this context, it is worth noting that neither the Coolpix A nor the E-P2 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-P2 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-P2 and their specifications in the Micro Four Thirds Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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. 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 imaging sensor is a crucial determinant 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. 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 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-P2 a Four Thirds sensor. The sensor area in the E-P2 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-P2 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 16.1MP, the Coolpix A offers a higher resolution than the E-P2 (12.2MP), but the Coolpix A nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 4.29μm for the E-P2) due to its larger sensor. Moreover, the Coolpix A is a much more recent model (by 3 years and 3 months) than the E-P2, and its sensor will 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 resolution advantage of the Nikon Coolpix A implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Coolpix A for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Olympus E-P2 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
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-P2 are ISO 100 to ISO 6400 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the Coolpix A provides substantially higher image quality than the E-P2, with an overall score that is 24 points higher. This advantage is based on 1.9 bits higher color depth, 3.4 EV in additional dynamic range, and 1.2 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 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, but the Coolpix A provides a higher video resolution than the E-P2. It can shoot video footage at 1080/30p, while the Olympus is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The Coolpix A and the E-P2 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-2 for the E-P2 – are available as accessories. The adjacent table lists some of the other core features of the Nikon Coolpix A and Olympus E-P2 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The Coolpix A has one, while the E-P2 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.
The Coolpix A writes its imaging data to SDXC cards, while the E-P2 uses SDHC 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-P2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the Coolpix A and the E-P2 have been discontinued, but can regularly be found used on eBay. The E-P2 was replaced by the Olympus E-P3, while the Coolpix A does not have a direct successor. 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 is the bottom line? Which of the two cameras – the Nikon Coolpix A or the Olympus E-P2 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Advantages of the Nikon Coolpix A:
- More detail: Offers more megapixels (16.1 vs 12.2MP) with a 17% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (24 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.9 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (3.4 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
- More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
- Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has a lens built-in, whereas the E-P2 requires a separate lens.
- More compact: Is smaller (111x64mm vs 121x70mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-P2).
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More modern: Reflects 3 years and 3 months of technical progress since the E-P2 launch.
Arguments in favor of the Olympus PEN E-P2:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (300 versus 230) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More heavily discounted: Has been around for much longer (launched in November 2009).
If the count of relative strengths (bullet points above) is taken as a measure, the Coolpix A is the clear winner of the match-up (15 : 6 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.

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 Coolpix A or the E-P2. 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

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. Also, please note that some of the review sites have changed their methodology and reporting over time.
