Nikon D100 vs Olympus E-PL2
The Nikon D100 and the Olympus PEN E-PL2 are two digital cameras that were announced, respectively, in February 2002 and January 2011. The D100 is a DSLR, while the E-PL2 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D100) and a Four Thirds (E-PL2) sensor. The Nikon has a resolution of 6 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 D100 and the Olympus PEN E-PL2? 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 D100 and the Olympus E-PL2. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The E-PL2 can be obtained in four different colors (black, silver, red, white), while the D100 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-PL2 is considerably smaller (51 percent) than the Nikon D100. Moreover, the E-PL2 is substantially lighter (54 percent) than the D100. In this context, it is worth noting that neither the D100 nor the E-PL2 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 (D100) and the Micro Four Thirds Lens Catalog (E-PL2). Mirrorless cameras, such as the E-PL2, 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-PL2 was launched at a markedly lower price (by 70 percent) than the D100, which puts it into a different market segment. 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D100 features an APS-C sensor and the Olympus E-PL2 a Four Thirds sensor. The sensor area in the E-PL2 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 D100 has a native 3:2 aspect ratio, while the one in the E-PL2 offers a 4:3 aspect.
Despite having a smaller sensor, the E-PL2 offers a higher resolution of 12.2 megapixels, compared with 6 MP of the D100. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 7.85μm for the D100). However, it should be noted that the E-PL2 is much more recent (by 8 years and 10 months) than the D100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Olympus E-PL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL2 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inches or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inches or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inches or 34.1 x 25.6 cm. The corresponding values for the Nikon D100 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.
The Nikon D100 has a native sensitivity range from ISO 200 to ISO 800, which can be extended to ISO 200-1600. The corresponding ISO settings for the Olympus PEN E-PL2 are ISO 200 to ISO 6400 (no boost).
In terms of underlying technology, the D100 is build around a CCD sensor, while the E-PL2 uses a CMOS imager. 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"). 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 E-PL2 indeed provides for movie recording, while the D100 does not. The highest resolution format that the E-PL2 can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the D100 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL2 relies on live view and the rear LCD for framing. That said, the E-PL2 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 D100, the Olympus E-PL2, and comparable cameras.

One feature that is present on the D100, but is missing on the E-PL2 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The D100 writes its imaging data to Compact Flash cards, while the E-PL2 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 D100 and Olympus PEN E-PL2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D100 and the E-PL2 have been discontinued, but can regularly be found used on ebay. The D100 was replaced by the Nikon D200, while the E-PL2 was followed by the Olympus E-PL3. Further information on the features and operation of the D100 and E-PL2 can be found, respectively, in the Nikon D100 Manual (free pdf) or the online Olympus E-PL2 Manual.
So what is the bottom line? Is the Nikon D100 better than the Olympus E-PL2 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Nikon D100:
- 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.
- Longer lasting: Can take more shots (370 versus 280) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in February 2002).
Arguments in favor of the Olympus PEN E-PL2:
- More detail: Has more megapixels (12.2 vs 6MP), which boosts linear resolution by 40%.
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 118k dots).
- More compact: Is smaller (114x72mm vs 144x116mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 418g or 54 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.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- More affordable: Was introduced into a lower priced category (70 percent cheaper at launch).
- More modern: Reflects 8 years and 10 months of technical progress since the D100 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the E-PL2 is the clear winner of the contest (11 : 4 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 D100 and the Olympus E-PL2 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D100 or the E-PL2. 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.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
