Nikon D3X vs Olympus E-620
The Nikon D3X and the Olympus E-620 are two digital cameras that were announced, respectively, in December 2008 and February 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D3X) and a Four Thirds (E-620) sensor. The Nikon has a resolution of 24.4 megapixels, whereas the Olympus provides 12.2 MP.
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 D3X 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 side-by-side display below illustrates the physical size and weight of the Nikon D3X and the Olympus E-620. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size 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 considerably smaller (51 percent) than the Nikon D3X. Moreover, the E-620 is substantially lighter (59 percent) than the D3X. It is worth mentioning in this context that the D3X is splash and dust resistant, while the E-620 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 (D3X) and the Four Thirds Lens Catalog (E-620).
Concerning battery life, the D3X gets 4400 shots out of its EN-EL4a battery, while the E-620 can take 500 images on a single charge of its BLS-1 power pack. As can be seen in the images above, the D3X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the E-620, Olympus provides the HLD-5 vertical grip as an optional accessory (see here on eBay).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 E-620 was launched at a markedly lower price (by 91 percent) than the D3X, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the imaging sensor is a crucial determinant 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. 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 Nikon D3X features a full frame sensor and the Olympus E-620 a Four Thirds sensor. The sensor area in the E-620 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the D3X has a native 3:2 aspect ratio, while the one in the E-620 offers a 4:3 aspect.
With 24.4MP, the D3X offers a higher resolution than the E-620 (12.2MP), but the D3X nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.29μm for the E-620) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.
The resolution advantage of the Nikon D3X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3X for good quality output (200 dots per inch) amounts to 30.2 x 20.2 inch or 76.8 x 51.2 cm, for very good quality (250 dpi) 24.2 x 16.1 inch or 61.4 x 41 cm, and for excellent quality (300 dpi) 20.2 x 13.4 inch or 51.2 x 34.1 cm. The corresponding values for the Olympus E-620 are 20.2 x 15.1 inch or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inch or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inch or 34.1 x 25.6 cm for excellent quality prints.
The Nikon D3X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-6400. The corresponding ISO settings for the Olympus E-620 are ISO 100 to ISO 3200 (no boost).
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 D3X provides substantially higher image quality than the E-620, with an overall score that is 33 points higher. This advantage is based on 3.4 bits higher color depth, 3.4 EV in additional dynamic range, and 1.9 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.

Apart from body and sensor, cameras can and do differ across a range of features. The D3X 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 viewfinder in the D3X offers a wider field of view (100%) 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 D3X has a higher magnification (0.70x vs 0.48x), 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 D3X and Olympus E-620 along with similar information for a selection of comparators.

One feature that is present on the D3X, but is missing on the E-620 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The E-620 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 D3X does not have a selfie-screen.
The Nikon D3X 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 D3X writes its imaging data to Compact Flash cards, while the E-620 uses Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
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 D3X and Olympus E-620 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D3X (unlike the E-620) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the D3X 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 D3X does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Olympus websites.
So what is the bottom line? Is the Nikon D3X better than the Olympus E-620 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Nikon D3X:
- More detail: Offers more megapixels (24.4 vs 12.2MP) with a 44% higher linear resolution.
- Better image quality: Scores substantially higher (33 points) in the DXO overall assessment.

- More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
If the count of individual advantages (bullet points above) is taken as a guide, the D3X is the clear winner of the match-up (17 : 7 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 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 D3X 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the D3X 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 why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
