Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D80 and the Olympus E-420? 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 physical size and weight of the Nikon D80 and the Olympus E-420 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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-420 is notably smaller (13 percent) than the Nikon D80. Moreover, the E-420 is markedly lighter (34 percent) than the D80. In this context, it is worth noting that neither the D80 nor the E-420 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 (D80) and the Four Thirds Lens Catalog (E-420).

Concerning battery life, the D80 gets 600 shots out of its Nikon EN-EL3e battery, while the E-420 can take 500 images on a single charge of its Olympus BLS-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

The price is, of course, an important factor in any camera decision. 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-420 was launched at a markedly lower price (by 40 percent) than the D80, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D80 features an APS-C sensor and the Olympus E-420 a Four Thirds sensor. The sensor area in the E-420 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 D80 has a native 3:2 aspect ratio, while the one in the E-420 offers a 4:3 aspect.

Even though the D80 has a larger sensor, both cameras offer the same resolution of 10 megapixels. This implies that the D80 has a lower pixel density and larger individual pixels (with a pixel pitch of 6.11μm versus 4.74μm for the E-420), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the E-420 is a somewhat more recent model (by 1 year and 6 months) than the D80, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Nikon D80 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Olympus E-420 are ISO 100 to ISO 1600 (no boost).

In terms of underlying technology, the D80 is build around a CCD sensor, while the E-420 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.

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"). Of the two cameras under review, the D80 has a notably higher overall DXO score than the E-420 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.8 EV in additional dynamic range, and -0 stops of reduced 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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D80 and the E-420 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 D80 has a higher magnification than the one of the E-420 (0.62x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D80, the Olympus E-420, and comparable cameras.

The D80 writes its imaging data to SDHC cards, while the E-420 uses Compact Flash or xD Picture cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D80 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 D80 and Olympus E-420 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D80 and the E-420 have been discontinued, but can regularly be found used on ebay. The D80 was replaced by the Nikon D90, while the E-420 does not have a direct successor. Further information on the features and operation of the D80 and E-420 can be found, respectively, in the Nikon D80 Manual (free pdf) or the online Olympus E-420 Manual.

Review summary

So what is the bottom line? Is the Nikon D80 better than the Olympus E-420 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Nikon D80:

• Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (0.8 EV of extra DR).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.62x vs 0.46x).
• Longer lasting: Can take more shots (600 versus 500) on a single battery charge.
• More heavily discounted: Has been on the market for longer (launched in August 2006).

Reasons to prefer the Olympus E-420:

• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (130x91mm vs 132x103mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 228g or 34 percent) and is thus easier to take along.
• 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 (40 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 6 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the E-420 emerges as the winner of the match-up (7 : 5 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 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 D80 and the Olympus E-420 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 incomplete and does no justice, for example, to the way the D80 or the E-420 perform in practice. 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 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.

Care should be taken when interpreting the review scores above, 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 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.
