Nikon D100 vs Olympus E-1
The Nikon D100 and the Olympus E-1 are two digital cameras that were revealed to the public, respectively, in February 2002 and June 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D100) and a Four Thirds (E-1) sensor. The Nikon has a resolution of 6 megapixels, whereas the Olympus provides 4.9 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 D100 and the Olympus E-1? 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 physical size and weight of the Nikon D100 and the Olympus E-1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-1 is notably smaller (12 percent) than the Nikon D100. Moreover, the E-1 is markedly lighter (5 percent) than the D100. It is noteworthy in this context that the E-1 is splash and dust-proof, while the D100 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 (D100) and the Four Thirds Lens Catalog (E-1).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will naturally be influenced heavily by the price. 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-1 was launched at a somewhat lower price (by 15 percent) than the D100, which makes it more attractive for photographers on a tight budget. 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.
The size of the imaging sensor is a crucial determinant 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 more expensive and 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-1 a Four Thirds sensor. The sensor area in the E-1 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-1 offers a 4:3 aspect.
In terms of underlying technology, both cameras are build around CCD sensors.
With 6MP, the D100 offers a higher resolution than the E-1 (4.9MP), but the D100 nevertheless has larger individual pixels (pixel pitch of 7.85μm versus 6.78μm for the E-1) due to its larger sensor. However, the E-1 is a somewhat more recent model (by 1 year and 4 months) than the D100, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Nikon D100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D100 for good quality output (200 dots per inch) amounts to 15 x 10 inch or 38.2 x 25.4 cm, for very good quality (250 dpi) 12 x 8 inch or 30.6 x 20.3 cm, and for excellent quality (300 dpi) 10 x 6.7 inch or 25.5 x 16.9 cm. The corresponding values for the Olympus E-1 are 12.8 x 9.6 inch or 32.5 x 24.4 cm for good quality, 10.2 x 7.7 inch or 26 x 19.5 cm for very good quality, and 8.5 x 6.4 inch or 21.7 x 16.3 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 E-1 are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Beyond body and sensor, cameras can and do differ across a range of features. The D100 and the E-1 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the E-1 offers a wider field of view (100%) than the one in the D100 (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the D100 has a higher magnification (0.53x vs 0.48x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D100 and Olympus E-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The D100 has one, while the E-1 does not. While the built-in flash of the D100 is not very powerful, it can at times be useful as a fill-in light.
The D100 writes its imaging data to Compact Flash cards, while the E-1 uses Compact Flash or xD Picture cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D100 only has one slot.
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 E-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-1 (unlike the D100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D100 and the E-1 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the E-1 was followed by the Olympus E-3. 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 D100 better than the Olympus E-1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Nikon D100:
- More detail: Offers more megapixels (6 vs 4.9MP) with a 13% higher linear resolution.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.48x).
- 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 February 2002).
Arguments in favor of the Olympus E-1:
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- More detailed LCD: Has a higher resolution rear screen (134k vs 118k dots).
- More compact: Is smaller (141x104mm vs 144x116mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (750 versus 370) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More affordable: Was released into a lower priced segment (15 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 4 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the E-1 emerges as the winner of the match-up (10 : 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 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-1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 remains incomplete and does no justice, for example, to the way the D100 or the E-1 perform in practice. 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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
