Olympus E-620 vs Nikon D90
The Olympus E-620 and the Nikon D90 are two digital cameras that were revealed to the public, respectively, in February 2009 and August 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a Four Thirds (E-620) and an APS-C (D90) 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 Olympus E-620 and the Nikon D90? 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
An illustration of the physical size and weight of the Olympus E-620 and the Nikon D90 is provided 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 Nikon D90 is notably larger (11 percent) than the Olympus E-620. Moreover, the D90 is substantially heavier (35 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the D90 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 Four Thirds Lens Catalog (E-620) and the Nikon Lens Catalog (D90).
Concerning battery life, the E-620 gets 500 shots out of its Olympus BLS-1 battery, while the D90 can take 850 images on a single charge of its Nikon EN-EL3e power pack.
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 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-620 was launched at a markedly lower price (by 46 percent) than the D90, 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.
Sensor comparison
The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-620 features a Four Thirds sensor and the Nikon D90 an APS-C sensor. The sensor area in the D90 is 66 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-620 has a native 4:3 aspect ratio, while the one in the D90 offers a 3:2 aspect.
Even though the D90 has a larger sensor, both cameras offer the same resolution of 12.2 megapixels. This implies that the D90 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. It should, however, be noted that the E-620 is a somewhat more recent model (by 5 months) than the D90, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Nikon D90 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 200-6400.
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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the D90 offers substantially better image quality than the E-620 (overall score 18 points higher). The advantage is based on 1.4 bits higher color depth, 2.2 EV in additional dynamic range, and 0.9 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D90 indeed provides for movie recording, while the E-620 does not. The highest resolution format that the D90 can use is 720/24p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a range of features. The E-620 and the D90 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 D90 offers a wider field of view (96%) than the one in the E-620 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D90 has a higher magnification (0.63x 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 Olympus E-620, the Nikon D90, and comparable cameras.

One feature that differentiates the E-620 and the D90 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the D90 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The E-620 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D90 does not have a selfie-screen.The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the D90 uses SDHC cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D90 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 Olympus E-620 and Nikon D90 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-620 and the D90 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, while the E-620 was followed by the Olympus E-600. Further information on the features and operation of the E-620 and D90 can be found, respectively, in the Olympus E-620 Manual (free pdf) or the online Nikon D90 Manual.
Review summary
So how do things add up? Is the Olympus E-620 better than the Nikon D90 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Olympus E-620:
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Less heavy: Is lighter (by 182g or 26 percent) and hence easier to carry around.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- 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 (46 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 5 months after the D90).
Arguments in favor of the Nikon D90:
- Better image quality: Scores substantially higher (18 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.2 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.9 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 720/24p video.
- More complete view: Has a viewfinder with a larger field of view (96% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.48x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- Faster burst: Shoots at higher frequency (4.5 vs 4 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (850 versus 500) out of a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in August 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the D90 is the clear winner of the contest (13 : 7 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 Olympus E-620 and the Nikon D90 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-620 or the D90. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
Expert reviews
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 (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. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
