Nikon D90 versus Nikon D7000

The Nikon D90 and the Nikon D7000 are two enthusiast cameras that were announced, respectively, in August 2008 and September 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The D90 has a resolution of 12.2 megapixel, whereas the D7000 provides 16.1 MP.

Body comparison

An illustration of the physical size and weight of the Nikon D90 and the Nikon D7000 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the D90 – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D7000 is somewhat larger (2 percent) than the Nikon D90. Moreover, the D7000 is markedly heavier (11 percent) than the D90. It is noteworthy in this context that the D7000 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Nikon Lens Catalog.

Concerning battery life, the D90 gets 850 shots out of its EN-EL3e battery, while the D7000 can take 1050 images on a single charge of its EN-EL15 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed 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 13 percent) than the D7000, 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 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D7000 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

Despite having a slightly smaller sensor, the D7000 offers a higher resolution of 16.1 megapixel, compared with 12.2 MP of the D90. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.80μm versus 5.53μm for the D90). However, it should be noted that the D7000 is much more recent (by 2 years) than the D90, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

D90 versus D7000 MP
Sensor resolution

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 consideration, the D7000 has a markedly higher DXO score than the D90 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.8 bits higher color depth, 1.4 EV in additional dynamic range, and 0.3 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 are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D7000 provides a better video resolution than the D90. It can shoot movie footage at 10800/24p, while the D90 is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D90 and the D7000 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 following table reports on some other key feature differences and similarities of the Nikon D90, the Nikon D7000, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the D90 and the D7000 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, while the D7000 was followed by the Nikon D7100.

Summary

So how do things add up? Which of the two cameras – the Nikon D90 or the Nikon D7000 – has the upper hand? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Nikon D90:

  • Less heavy: Is lighter (by 77g or 10 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in August 2008).

Reasons to prefer the Nikon D7000:

  • More detail: Has more megapixels (16.1 vs 12.2MP), which boosts linear resolution by 15%.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
  • Better video: Provides higher definition movie capture (10800/24p vs 720/24p).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (6 vs 4.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (1050 versus 850) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Reflects 2 years of technical progress since the D90 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D7000 is the clear winner of the contest (9 : 3 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the D90 or the D7000 handle or perform in practice. 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 expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
