Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D7000 and the Olympus E-510? 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 D7000 and the Olympus E-510 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 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-510 is notably smaller (10 percent) than the Nikon D7000. Moreover, the E-510 is markedly lighter (31 percent) than the D7000. It is worth mentioning in this context that the D7000 is splash and dust resistant, while the E-510 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 (D7000) and the Four Thirds Lens Catalog (E-510).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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-510 was launched at a markedly lower price (by 47 percent) than the D7000, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 D7000 features an APS-C sensor and the Olympus E-510 a Four Thirds sensor. The sensor area in the E-510 is 39 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 D7000 has a native 3:2 aspect ratio, while the one in the E-510 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 16.1MP, the D7000 offers a higher resolution than the E-510 (10MP), but the D7000 nevertheless has marginally larger individual pixels (pixel pitch of 4.80μm versus 4.74μm for the E-510) due to its larger sensor. Moreover, the D7000 is a much more recent model (by 3 years and 6 months) than the E-510, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
The resolution advantage of the Nikon D7000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7000 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Olympus E-510 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 D7000 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus E-510 are ISO 100 to ISO 1600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the D7000 provides substantially higher image quality than the E-510, with an overall score that is 28 points higher. This advantage is based on 2.3 bits higher color depth, 3.9 EV in additional dynamic range, and 1.4 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.
|Olympus E-510||Four Thirds||10.0||3648||2736||none||21.2||10.0||442||52|
|Nikon Df||Full Frame||16.2||4928||3280||none||24.6||13.1||3279||89|

Many modern cameras are not only capable of taking still images, but can also record movies. The D7000 indeed provides movie recording capabilities, while the E-510 does not. The highest resolution format that the D7000 can use is 10800/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. The D7000 and the E-510 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 D7000 offers a wider field of view (100%) than the one in the E-510 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D7000 has a higher magnification (0.63x vs 0.46x), 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 D7000 and Olympus E-510 along with similar information for a selection of comparators.
One feature that is present on the D7000, but is missing on the E-510 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 Nikon D7000 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 D7000 writes its imaging data to SDXC cards, while the E-510 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 D7000 and Olympus E-510 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D7000 and the E-510 have been discontinued, but can regularly be found used on eBay. The E-510 was replaced by the Olympus E-520, while the D7000 was followed by the Nikon D7100. 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 D7000 better than the Olympus E-510 or vice versa? The listing below highlights the relative strengths of the two models.
Advantages of the Nikon D7000:

- 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 (921k vs 215k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Can take more shots (1050 versus 750) on a single battery charge.
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- More modern: Reflects 3 years and 6 months of technical progress since the E-510 launch.
Arguments in favor of the Olympus E-510:
- Less heavy: Has a lower weight (by 242g or 31 percent) and is thus easier to take along.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in March 2007).
If the count of relative strengths (bullet points above) is taken as a measure, the D7000 is the clear winner of the match-up (17 : 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 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D7000 or the E-510. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
