Nikon D7000 vs Olympus E-PL7
The Nikon D7000 and the Olympus PEN E-PL7 are two digital cameras that were revealed to the public, respectively, in September 2010 and August 2014. The D7000 is a DSLR, while the E-PL7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D7000) and a Four Thirds (E-PL7) sensor. The Nikon has a resolution of 16.1 megapixels, whereas the Olympus provides 15.9 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 D7000 and the Olympus PEN E-PL7? 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-PL7 are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.
The E-PL7 can be obtained in two different colors (black, silver), while the D7000 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL7 is considerably smaller (44 percent) than the Nikon D7000. Moreover, the E-PL7 is substantially lighter (54 percent) than the D7000. It is worth mentioning in this context that the D7000 is splash and dust resistant, while the E-PL7 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 Micro Four Thirds Lens Catalog (E-PL7). Mirrorless cameras, such as the E-PL7, 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 would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-PL7 was launched at a markedly lower price (by 60 percent) than the D7000, 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 sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D7000 features an APS-C sensor and the Olympus E-PL7 a Four Thirds sensor. The sensor area in the E-PL7 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-PL7 offers a 4:3 aspect.
With 16.1MP, the D7000 offers a slightly higher resolution than the E-PL7 (15.9MP), but the D7000 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the E-PL7) due to its larger sensor. However, the E-PL7 is a much more recent model (by 3 years and 11 months) than the D7000, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.
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 PEN E-PL7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 has a notably higher overall DXO score than the E-PL7 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 1.5 EV in additional dynamic range, and 0.4 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-PL7 provides a faster frame rate than the D7000. It can shoot movie footage at 1080/30p, while the Nikon is limited to 10800/24p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D7000 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL7 relies on live view and the rear LCD for framing. That said, the E-PL7 can be equipped with an optional viewfinder – the VF-4. The following table reports on some other key feature differences and similarities of the Nikon D7000, the Olympus E-PL7, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D7000 has one, while the E-PL7 does not. While the built-in flash of the D7000 is not very powerful, it can at times be useful as a fill-in light.The E-PL7 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 D7000 does not have a selfie-screen.
The Nikon D7000 and the Olympus E-PL7 both have 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.
Concerning the storage of imaging data, both the D7000 and the E-PL7 write their files to SDXC cards. The D7000 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PL7 only has one slot. The E-PL7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D7000 cannot take advantage of Ultra High Speed SD cards.
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 PEN E-PL7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D7000 has a microphone port, which is missing on the E-PL7. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the D7000 and the E-PL7 have been discontinued, but can regularly be found used on eBay. The D7000 was replaced by the Nikon D7100, while the E-PL7 was followed by the Olympus E-PL8. 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 conclusions can be drawn? Which of the two cameras – the Nikon D7000 or the Olympus E-PL7 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Nikon D7000:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.5 EV of extra DR).

If the number of relative strengths (bullet points above) is taken as a guide, the E-PL7 emerges as the winner of the match-up (14 : 12 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.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the D7000 and the E-PL7 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
