Nikon D90 vs Olympus E-3

The Nikon D90 and the Olympus E-3 are two digital cameras that were announced, respectively, in August 2008 and October 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D90) and a Four Thirds (E-3) sensor. The Nikon has a resolution of 12.2 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.

Body comparison

An illustration of the physical size and weight of the Nikon D90 and the Olympus E-3 is provided 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 size dimensions are rounded to the nearest millimeter.

Size Nikon D90 vs Olympus E-3
Compare D90 versus E-3 top
Comparison D90 or E-3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-3 is notably larger (21 percent) than the Nikon D90. Moreover, the E-3 is markedly heavier (25 percent) than the D90. It is noteworthy in this context that the E-3 is splash and dust-proof, while the D90 does not feature any corresponding weather-sealing.

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 (D90) and the Four Thirds Lens Catalog (E-3).

Concerning battery life, the D90 gets 850 shots out of its Nikon EN-EL3e battery, while the E-3 can take 750 images on a single charge of its Olympus BLM-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 D90 was launched at a somewhat lower price (by 24 percent) than the E-3, which makes it more attractive for photographers on a tight budget. 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.

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 D90 features an APS-C sensor and the Olympus E-3 a Four Thirds sensor. The sensor area in the E-3 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 D90 has a native 3:2 aspect ratio, while the one in the E-3 offers a 4:3 aspect.

Nikon D90 and Olympus E-3 sensor measures

With 12.2MP, the D90 offers a higher resolution than the E-3 (10MP), but the D90 nevertheless has larger individual pixels (pixel pitch of 5.53μm versus 4.74μm for the E-3) due to its larger sensor. Moreover, the D90 is a somewhat more recent model (by 10 months) than the E-3, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon D90 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D90 for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.5 x 36.2 cm, for very good quality (250 dpi) 17.2 x 11.4 inches or 43.6 x 28.9 cm, and for excellent quality (300 dpi) 14.3 x 9.5 inches or 36.3 x 24.1 cm. The corresponding values for the Olympus E-3 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Nikon D90 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-3 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.

D90 versus E-3 MP

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 review, the D90 provides substantially higher image quality than the E-3, with an overall score that is 17 points higher. This advantage is based on 1.1 bits higher color depth, 2 EV in additional dynamic range, and 0.8 stops in additional 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 range of features. The D90 and the E-3 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 E-3 offers a wider field of view (100%) than the one in the D90 (96%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the D90 has a higher magnification (0.63x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D90 and Olympus E-3 along with similar information for a selection of comparators.

One feature that differentiates the E-3 and the D90 is in-body image stabilization (IBIS). The E-3 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-3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D90 does not have a selfie-screen.

The D90 writes its imaging data to SDHC cards, while the E-3 uses Compact Flash or xD Picture cards. The E-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D90 only has one slot.

Studio photographers will appreciate that the Olympus E-3 (unlike the D90) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D90 and the E-3 have been discontinued, but can regularly be found used on ebay. The E-3 was replaced by the Olympus E-5, while the D90 was followed by the Nikon D7000. Further information on the features and operation of the D90 and E-3 can be found, respectively, in the Nikon D90 Manual (free pdf) or the online Olympus E-3 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Nikon D90 and the Olympus E-3? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Nikon D90:

  • More detail: Offers more megapixels (12.2 vs 10MP) with a 13% higher linear resolution.
  • Better image quality: Scores substantially higher (17 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (2 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.8 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 (0.63x vs 0.58x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
  • More compact: Is smaller (132x103mm vs 142x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 173g or 20 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (850 versus 750) on a single battery charge.
  • More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 10 months after the E-3).

ilogo

Arguments in favor of the Olympus E-3:

  • More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
  • 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.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • 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 October 2007).

If the count of relative strengths (bullet points above) is taken as a measure, the D90 is the clear winner of the match-up (14 : 9 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 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.

D90 14:09 E-3

How about other alternatives? Do the specifications of the Nikon D90 and the Olympus E-3 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D90 or the E-3. 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.

Expert reviews

This is why hands-on reviews by experts are important. 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
