Nikon D3000 vs Olympus E-420
The Nikon D3000 and the Olympus E-420 are two digital cameras that were announced, respectively, in July 2009 and March 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D3000) and a Four Thirds (E-420) sensor. Both cameras offer a resolution of 10 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 D3000 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.
The physical size and weight of the Nikon D3000 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 consecutive perspectives from the front, the top, and the back are available. 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 somewhat smaller (3 percent) than the Nikon D3000. Moreover, the E-420 is markedly lighter (18 percent) than the D3000. In this context, it is worth noting that neither the D3000 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 (D3000) and the Four Thirds Lens Catalog (E-420).
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 two cameras under review were launched at the same price and fall into the same 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.
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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon D3000 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 D3000 has a native 3:2 aspect ratio, while the one in the E-420 offers a 4:3 aspect.
Even though the D3000 has a larger sensor, both cameras offer the same resolution of 10 megapixels. This implies that the D3000 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. In addition, the D3000 is a somewhat more recent model (by 1 year and 4 months) than the E-420, and its sensor might have benefitted from technological advances during this time.
The Nikon D3000 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 D3000 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 D3000 has a notably higher overall DXO score than the E-420 (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.7 EV in additional dynamic range, and 0.1 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.

Apart from body and sensor, cameras can and do differ across a variety of features. The D3000 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 D3000 has a higher magnification than the one of the E-420 (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 D3000 and Olympus E-420 in connection with corresponding information for a sample of similar cameras.

The D3000 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 D3000 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 D3000 and Olympus E-420 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D3000 and the E-420 have been discontinued, but can regularly be found used on ebay. The D3000 was replaced by the Nikon D3100, while the E-420 does not have a direct successor. Further information on the features and operation of the D3000 and E-420 can be found, respectively, in the Nikon D3000 Manual (free pdf) or the online Olympus E-420 Manual.
So what conclusions can be drawn? Which of the two cameras – the Nikon D3000 or the Olympus E-420 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Nikon D3000:
- Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.46x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More modern: Is somewhat more recent (announced 1 year and 4 months after the E-420).
Advantages of the Olympus E-420:
- Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 96g or 18 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 heavily discounted: Has been on the market for longer (launched in March 2008).
If the count of relative strengths (bullet points above) is taken as a measure, the D3000 comes out slightly ahead of the E-420 (5 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 D3000 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the D3000 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.
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 (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 review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
