Panasonic G9 versus Nikon D7000

The Panasonic Lumix DC-G9 and the Nikon D7000 are two enthusiast cameras that were revealed to the public, respectively, in November 2017 and September 2010. The G9 is a mirrorless interchangeable lens camera, while the D7000 is a DSLR. The cameras are based on a Four Thirds (G9) and an APS-C (D7000) sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Nikon provides 16.1 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Panasonic G9 vs Nikon D7000

The physical size and weight of the Panasonic G9 and the Nikon D7000 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. 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 side – the G9 – 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 Nikon D7000 is somewhat larger (4 percent) than the Panasonic G9. Moreover, the D7000 is markedly heavier (19 percent) than the G9. 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 Micro Four Thirds Lens Catalog (G9) and the Nikon Lens Catalog (D7000). Mirrorless cameras, such as the Panasonic G9, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the G9 gets 400 shots out of its DMW-BLF19 battery, while the D7000 can take 1050 images on a single charge of its EN-EL15 power pack.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D7000 was launched at a somewhat lower price (by 12 percent) than the G9, 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: Panasonic G9 vs Nikon D7000

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic G9 features a Four Thirds sensor and the Nikon D7000 an APS-C sensor. The sensor area in the D7000 is 65 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the G9 has a native 4:3 aspect ratio, while the one in the D7000 offers a 3:2 aspect.

Panasonic G9 and Nikon D7000 sensor measures

Despite having a smaller sensor, the Panasonic G9 offers a higher resolution of 20.2 megapixel, compared with 16.1 MP of the Nikon D7000. 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 3.34μm versus 4.80μm for the D7000). However, it should be noted that the G9 is much more recent (by 7 years and 1 month) than the D7000, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the G9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Unlike the D7000, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

G9 versus D7000 MP

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"). 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 G9 provides a higher video resolution than the D7000. It can shoot video footage at 4K/60p, while the Nikon is limited to 10800/24p.

 

Feature comparison: Panasonic G9 vs Nikon D7000

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G9 has an electronic viewfinder (3680k 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 following table reports on some other key feature differences and similarities of the Panasonic G9, the Nikon D7000, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that differentiates the G9 and the D7000 is in-body image stabilization (IBIS). The G9 reduces the risk of handshake-induced blur with all attached lenses, while the D7000 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the G9 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the G9 and the D7000 write their imaging data to SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

The G9 is a recent model that features in the current product line-up of Panasonic. In contrast, the D7000 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D7000 was succeeded by the Nikon D7100.

Review summary: Panasonic G9 vs Nikon D7000

So how do things add up? Which of the two cameras – the Panasonic G9 or the Nikon D7000 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Panasonic Lumix DC-G9:

  • More detail: Offers more megapixels (20.2 vs 16.1MP) with a 10% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher definition movie capture (4K/60p vs 10800/24p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (20 vs 6 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Less heavy: Is lighter (by 122g or 16 percent) and hence easier to carry around.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • More modern: Reflects 7 years and 1 month of technical progress since the D7000 launch.

ilogo

Reasons to prefer the Nikon D7000:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Longer lasting: Gets more shots (1050 versus 400) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was released into a lower priced segment (12 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in September 2010).

If the count of individual advantages (bullet points above) is taken as a guide, the G9 is the clear winner of the match-up (19 : 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.

G9 19:06 D7000

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G9 or the D7000. 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 where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.
