Nikon D5000 vs Olympus E-620
The Nikon D5000 and the Olympus E-620 are two digital cameras that were officially introduced, respectively, in April 2009 and February 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D5000) and a Four Thirds (E-620) sensor. Both cameras offer a resolution of 12.2 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 D5000 and the Olympus E-620? 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 D5000 and the Olympus E-620 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 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-620 is notably smaller (7 percent) than the Nikon D5000. Moreover, the E-620 is markedly lighter (12 percent) than the D5000. In this context, it is worth noting that neither the D5000 nor the E-620 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 (D5000) and the Four Thirds Lens Catalog (E-620).

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-620 was somewhat cheaper (by 7 percent) than the D5000 at launch, but both cameras fall into the same price category. 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 D5000 features an APS-C sensor and the Olympus E-620 a Four Thirds sensor. The sensor area in the E-620 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 D5000 has a native 3:2 aspect ratio, while the one in the E-620 offers a 4:3 aspect.
Even though the D5000 has a larger sensor, both cameras offer the same resolution of 12.2 megapixels. This implies that the D5000 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.53μm versus 4.29μm for the E-620), which gives it a potential advantage in terms of light gathering capacity. The two cameras were released in close succession, so that their sensors are from the same technological generation.
The Nikon D5000 has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 200-6400. The corresponding ISO settings for the Olympus E-620 are ISO 100 to ISO 3200 (no boost).
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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"). Of the two cameras under review, the D5000 provides substantially higher image quality than the E-620, with an overall score that is 17 points higher. This advantage is based on 1.4 bits higher color depth, 2.2 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The D5000 indeed provides movie recording capabilities, while the E-620 does not. The highest resolution format that the D5000 can use is 720/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. The D5000 and the E-620 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 D5000 has a higher magnification than the one of the E-620 (0.51x vs 0.48x), 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 D5000, the Olympus E-620, and comparable cameras.

One feature that differentiates the E-620 and the D5000 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the D5000 offers no blur reduction with lenses that themselves do not provide optical image stabilization.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The Nikon D5000 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The D5000 writes its imaging data to SDHC cards, while the E-620 uses Compact Flash or xD Picture cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D5000 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 D5000 and Olympus E-620 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D5000 and the E-620 have been discontinued, but can regularly be found used on ebay. The E-620 was replaced by the Olympus E-600, while the D5000 was followed by the Nikon D5100. Further information on the features and operation of the D5000 and E-620 can be found, respectively, in the Nikon D5000 Manual (free pdf) or the online Olympus E-620 Manual.
So what is the bottom line? Is there a clear favorite between the Nikon D5000 and the Olympus E-620? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Nikon D5000:
- Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.4 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.2 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.7 stops ISO advantage).
- Broader imaging potential: Can record not only still images but also 720/24p movies.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.51x vs 0.48x).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
Arguments in favor of the Olympus E-620:
- Less heavy: Has a lower weight (by 69g or 12 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
If the count of individual advantages (bullet points above) is taken as a guide, the D5000 is the clear winner of the match-up (7 : 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 D5000 and the Olympus E-620 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 says little about, for example, the shooting experience and imaging performance of the D5000 and the E-620 in practical situations. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
