Nikon D300S vs Olympus E-P2
The Nikon D300S and the Olympus PEN E-P2 are two enthusiast cameras that were announced, respectively, in July 2009 and November 2009. The D300S is a DSLR, while the E-P2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D300S) and a Four Thirds (E-P2) sensor. Both cameras offer a resolution of 12.2 megapixels.
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 D300S 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.
Body comparison
The side-by-side display below illustrates the physical size and weight of the Nikon D300S and the Olympus E-P2. 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 E-P2 can be obtained in three different colors (black, silver, white), while the D300S 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-P2 is considerably smaller (50 percent) than the Nikon D300S. Moreover, the E-P2 is substantially lighter (62 percent) than the D300S. It is worth mentioning in this context that the D300S is splash and dust resistant, while the E-P2 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 (D300S) and the Micro Four Thirds Lens Catalog (E-P2). Mirrorless cameras, such as the E-P2, 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 D300S gets 950 shots out of its Nikon EN-EL3e battery, while the E-P2 can take 300 images on a single charge of its Olympus BLS-1 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-P2 was launched at a markedly lower price (by 56 percent) than the D300S, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 D300S features an APS-C sensor and the Olympus E-P2 a Four Thirds sensor. The sensor area in the E-P2 is 40 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 D300S has a native 3:2 aspect ratio, while the one in the E-P2 offers a 4:3 aspect.
Even though the D300S has a larger sensor, both cameras offer the same resolution of 12.2 megapixels. This implies that the D300S has a lower pixel density and larger individual pixels (with a pixel pitch of 5.53μm versus 4.29μm for the E-P2), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the E-P2 is a somewhat more recent model (by 3 months) than the D300S, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Nikon D300S has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Olympus PEN E-P2 are ISO 100 to ISO 6400 (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.
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 D300S provides substantially higher image quality than the E-P2, with an overall score that is 14 points higher. This advantage is based on 1 bits higher color depth, 1.8 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. 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 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 E-P2 provides a faster frame rate than the D300S. It can shoot movie footage at 720/30p, while the Nikon is limited to 720/24p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D300S has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P2 relies on live view and the rear LCD for framing. That said, the E-P2 can be equipped with an optional viewfinder – the VF-2. The following table reports on some other key feature differences and similarities of the Nikon D300S, the Olympus E-P2, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D300S has one, while the E-P2 does not. While the built-in flash of the D300S is not very powerful, it can at times be useful as a fill-in light.
The Nikon D300S 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 D300S writes its imaging data to Compact Flash or SDXC cards, while the E-P2 uses SDHC cards. The D300S features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P2 only has one slot.
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 D300S and Olympus PEN E-P2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D300S has a microphone port, which is missing on the E-P2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Studio photographers will appreciate that the Nikon D300S (unlike the E-P2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D300S and the E-P2 have been discontinued, but can regularly be found used on ebay. The D300S was replaced by the Nikon D500, while the E-P2 was followed by the Olympus E-P3. Further information on the features and operation of the D300S and E-P2 can be found, respectively, in the Nikon D300S Manual (free pdf) or the online Olympus E-P2 Manual.
Review summary
So how do things add up? Is the Nikon D300S better than the Olympus E-P2 or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Nikon D300S:
- Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.8 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.6 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.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (950 versus 300) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.

Reasons to prefer the Olympus PEN E-P2:
- Better video: Provides higher movie framerates (720/30p versus 720/24p).
- More compact: Is smaller (121x70mm vs 147x115mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 583g or 62 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 (56 percent cheaper at launch).
- More modern: Was introduced somewhat (3 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the D300S is the clear winner of the match-up (16 : 7 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 D300S and the Olympus E-P2 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 says little about, for example, the shooting experience and imaging performance of the D300S and the E-P2 in practical situations. 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.

The above review scores should be interpreted with care, 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 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.
