Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D7000 and the Panasonic Lumix DMC-GH2? 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Nikon D7000 and the Panasonic GH2. 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 dimensions are rounded to the nearest millimeter.

The GH2 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 Panasonic GH2 is notably smaller (19 percent) than the Nikon D7000. Moreover, the GH2 is substantially lighter (43 percent) than the D7000. It is worth mentioning in this context that the D7000 is splash and dust resistant, while the GH2 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 (GH2). Mirrorless cameras, such as the GH2, 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.

Concerning battery life, the D7000 gets 1050 shots out of its Nikon EN-EL15 battery, while the GH2 can take 330 images on a single charge of its Panasonic DMW-BLC12 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 GH2 was launched at a markedly lower price (by 40 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.

Sensor comparison

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 Panasonic GH2 a Four Thirds sensor. The sensor area in the GH2 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 GH2 offers a 4:3 aspect.

With 16.1MP, the D7000 offers a slightly higher resolution than the GH2 (15.9MP), but the D7000 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the GH2) 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 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 Panasonic Lumix DMC-GH2 are ISO 160 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 provides substantially higher image quality than the GH2, with an overall score that is 20 points higher. This advantage is based on 2.3 bits higher color depth, 2.6 EV in additional dynamic range, and 0.8 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the GH2 provides a faster frame rate than the D7000. It can shoot movie footage at 1080/60i, while the Nikon is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GH2 has an electronic viewfinder (1534k 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the GH2 has a higher magnification than the one of the D7000 (0.71x vs 0.63x), 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 Panasonic GH2 along with similar information for a selection of comparators.

One feature that is present on the D7000, but is missing on the GH2 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.

Concerning the storage of imaging data, both the D7000 and the GH2 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 GH2 only has one slot.

Connectivity comparison

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 Panasonic Lumix DMC-GH2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D7000 and the GH2 have been discontinued, but can regularly be found used on ebay. The D7000 was replaced by the Nikon D7100, while the GH2 was followed by the Panasonic GH3. Further information on the features and operation of the D7000 and GH2 can be found, respectively, in the Nikon D7000 Manual (free pdf) or the online Panasonic GH2 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon D7000 and the Panasonic GH2? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Nikon D7000:

• Better image quality: Scores substantially higher (20 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.3 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2.6 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• More detailed LCD: Has a higher resolution rear screen (921k vs 460k 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 330) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.

Arguments in favor of the Panasonic Lumix DMC-GH2:

• Better video: Provides higher movie framerates (1080/60i versus 1080/24p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.63x).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (124x90mm vs 132x105mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 338g or 43 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).

If the count of individual advantages (bullet points above) is taken as a guide, the D7000 is the clear winner of the match-up (13 : 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 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.

How about other alternatives? Do the specifications of the Nikon D7000 and the Panasonic GH2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the D7000 and the GH2 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.

Expert reviews

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 (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
