Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D7000 and the Panasonic Lumix DMC-GF2? 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 physical size and weight of the Nikon D7000 and the Panasonic GF2 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 dimensions are rounded to the nearest millimeter.

The GF2 can be obtained in four different colors (black, silver, red, white), 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 GF2 is considerably smaller (45 percent) than the Nikon D7000. Moreover, the GF2 is substantially lighter (60 percent) than the D7000. It is worth mentioning in this context that the D7000 is splash and dust resistant, while the GF2 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 (GF2). Mirrorless cameras, such as the GF2, 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 GF2 can take 300 images on a single charge of its Panasonic DMW-BLD10 power pack.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The GF2 was launched at a markedly lower price (by 63 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. 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. 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 Panasonic GF2 a Four Thirds sensor. The sensor area in the GF2 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 GF2 offers a 4:3 aspect.

With 16.1MP, the D7000 offers a higher resolution than the GF2 (12MP), but the D7000 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 4.33μm for the GF2) 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 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 Panasonic GF2 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 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 Panasonic Lumix DMC-GF2 are ISO 100 to ISO 6400 (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 GF2, with an overall score that is 26 points higher. This advantage is based on 2.3 bits higher color depth, 3.6 EV in additional dynamic range, and 1.2 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GF2 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

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 GF2 relies on live view and the rear LCD for framing. That said, the GF2 can be equipped with an optional viewfinder – the DMW-LVF1. The following table reports on some other key feature differences and similarities of the Nikon D7000, the Panasonic GF2, and comparable cameras.

One feature that is present on the D7000, but is missing on the GF2 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 GF2 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 GF2 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-GF2 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 GF2. 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 GF2 have been discontinued, but can regularly be found used on ebay. The D7000 was replaced by the Nikon D7100, while the GF2 was followed by the Panasonic GF3. Further information on the features and operation of the D7000 and GF2 can be found, respectively, in the Nikon D7000 Manual (free pdf) or the online Panasonic GF2 Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon D7000 or the Panasonic GF2 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Nikon D7000:

• More detail: Offers more megapixels (16.1 vs 12MP) with a 18% higher linear resolution.
• Better image quality: Scores substantially higher (26 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 (3.6 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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 2.6 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 300) 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.

Reasons to prefer the Panasonic Lumix DMC-GF2:

• Better video: Provides higher movie framerates (1080/60i versus 1080/24p).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More compact: Is smaller (113x68mm vs 132x105mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 470g or 60 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 (63 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 (15 : 6 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.

How about other alternatives? Do the specifications of the Nikon D7000 and the Panasonic GF2 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 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 GF2. 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 where reviews by experts come in. 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.

Care should be taken when interpreting the review scores above, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
