Nikon D100 vs Olympus E-450
The Nikon D100 and the Olympus E-450 are two digital cameras that were announced, respectively, in February 2002 and March 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D100) and a Four Thirds (E-450) sensor. The Nikon has a resolution of 6 megapixels, whereas the Olympus provides 10 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-450? 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-450. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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-450 is notably smaller (29 percent) than the Nikon D100. Moreover, the E-450 is substantially lighter (44 percent) than the D100. In this context, it is worth noting that neither the D100 nor the E-450 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 Four Thirds Lens Catalog (E-450).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
The price is, of course, an important factor in any camera decision. 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-450 was launched at a markedly lower price (by 75 percent) than the D100, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 D100 features an APS-C sensor and the Olympus E-450 a Four Thirds sensor. The sensor area in the E-450 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-450 offers a 4:3 aspect.
Despite having a smaller sensor, the E-450 offers a higher resolution of 10 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 4.74μm versus 7.85μm for the D100). However, it should be noted that the E-450 is much more recent (by 7 years and 1 month) 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-450 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-450 for good quality output (200 dots per inch) amounts to 18.2 x 13.7 inch or 46.3 x 34.7 cm, for very good quality (250 dpi) 14.6 x 10.9 inch or 37.1 x 27.8 cm, and for excellent quality (300 dpi) 12.2 x 9.1 inch or 30.9 x 23.2 cm. The corresponding values for the Nikon D100 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch 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 E-450 are ISO 100 to ISO 1600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Apart from body and sensor, cameras can and do differ across a range of features. The D100 and the E-450 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the D100 has a higher magnification than the one of the E-450 (0.53x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D100 and Olympus E-450 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D100, but is missing on the E-450 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-450 uses Compact Flash or xD Picture cards. The E-450 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-450 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D100 and the E-450 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the E-450 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 how do things add up? Is there a clear favorite between the Nikon D100 and the Olympus E-450? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Nikon D100:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.46x).
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- More heavily discounted: Has been available for much longer (launched in February 2002).
Advantages of the Olympus E-450:
- More detail: Has more megapixels (10 vs 6MP), which boosts linear resolution by 26%.
- Larger screen: Has a bigger rear LCD (2.7" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (215k vs 118k dots).
- Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (130x91mm vs 144x116mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 340g or 44 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (500 versus 370) out of a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More affordable: Was introduced into a lower priced category (75 percent cheaper at launch).
- More modern: Reflects 7 years and 1 month of technical progress since the D100 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the E-450 is the clear winner of the contest (11 : 3 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 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-450 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D100 or the E-450. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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 review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
