Nikon D7000 versus Olympus E-M5

The Nikon D7000 and the Olympus OM-D E-M5 are two enthusiast cameras that were officially introduced, respectively, in September 2010 and February 2012. The D7000 is a DSLR, while the E-M5 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D7000) and a Four Thirds sensor. The Nikon has a resolution of 16.1 megapixel, whereas the Olympus provides 15.9 MP.

Body comparison

The physical size and weight of the Nikon D7000 and the Olympus E-M5 are illustrated in the side-by-side display below. 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 you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the D7000 – represents the basis for the calculations 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 Olympus E-M5 is notably smaller (22 percent) than the Nikon D7000. Moreover, the E-M5 is substantially lighter (46 percent) than the D7000. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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 find an overview of optics for the two cameras in the Nikon Lens Catalog (D7000) and the Micro Four Thirds Lens Catalog (E-M5). Mirrorless cameras, such as the E-M5, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

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 E-M5 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. 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. 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 tent 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-M5 a Four Thirds sensor. The sensor area in the E-M5 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-M5 offers a 4:3 aspect.

Sensor size

With 16.1MP, the D7000 offers a slightly higher resolution than the E-M5 (15.9MP), but the D7000 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the E-M5) due to its larger sensor. However, the E-M5 is a somewhat more recent model (by 1 year and 4 months) than the D7000, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 D7000 has a notably higher overall DXO score than the E-M5 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 1.6 EV in additional dynamic range, and 0.5 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-M5 provides a faster frame rate than the D7000. It can shoot movie footage at 1080/60i, while the Nikon is limited to 10800/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M5 has an electronic viewfinder (1440k dots), while the D7000 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Nikon D7000 and Olympus E-M5 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the D7000 and the E-M5 have been discontinued, but can regularly be found used on ebay. The D7000 was replaced by the Nikon D7100, while the E-M5 was followed by the Olympus E-M5 II.

Summary

So how do things add up? Is there a clear favorite between the Nikon D7000 and the Nikon D7000? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Nikon D7000:

  • Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum of light and dark details (1.6 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (921k vs 610k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More heavily discounted: Has been on the market for longer (launched in September 2010).

Advantages of the Olympus OM-D E-M5:

  • Better video: Provides higher movie framerates (1080/60i vs 10800/24p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (9 vs 6 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (122x89mm vs 132x105mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 355g or 46 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 4 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M5 emerges as the winner of the match-up (11 : 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.

D7000 09:11 E-M5

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 handling experience and imaging performance when actually working with the D7000 or the E-M5. 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 table relays the overall verdicts of several of the most popular 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.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
