Nikon D7000 versus Canon G7 X

The Nikon D7000 and the Canon PowerShot G7 X are two digital cameras that were revealed to the public, respectively, in September 2010 and September 2014. The D7000 is a DSLR, while the G7X is a fixed lens compact. The cameras are based on an APS-C (D7000) and an one-inch (G7X) sensor. The Nikon has a resolution of 16.1 megapixel, whereas the Canon provides 20 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: Nikon D7000 vs Canon G7 X

The physical size and weight of the Nikon D7000 and the Canon G7 X are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display 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 – the D7000 – represents 100 percent 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 Canon G7 X is considerably smaller (55 percent) than the Nikon D7000. It is worth mentioning in this context that the D7000 is splash and dust resistant, while the G7X does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X has a lens build in, whereas the D7000 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the D7000 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D7000 gets 1050 shots out of its EN-EL15 battery, while the G7X can take 210 images on a single charge of its NB-13L power pack.

The camera’s price is obviously a critical decision-making factor. 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 G7X was launched at a lower price than the D7000, despite having a lens build in. 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.

 

Sensor comparison: Nikon D7000 vs Canon G7 X

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 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 Canon G7 X an one-inch sensor. The sensor area in the G7X is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D7000 and Canon G7 X sensor measures

Despite having a smaller sensor, the G7X offers a higher resolution of 20 megapixel, compared with 16.1 MP of the 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 2.41μm versus 4.80μm for the D7000). However, it should be noted that the G7X is much more recent (by 4 years) than the D7000, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

D7000 versus G7X MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 G7X (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.5 bits higher color depth, 1.2 EV in additional dynamic range, and 1.1 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 can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7X provides a faster frame rate than the D7000. It can shoot movie footage at 1080/60p, while the Nikon is limited to 10800/24p.

 

Feature comparison: Nikon D7000 vs Canon G7 X

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D7000 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Nikon D7000, the Canon G7 X, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

ilogo

Reasons to prefer the Canon PowerShot G7 X:

  • More detail: Has more megapixels (20 vs 16.1MP), which boosts linear resolution by 11%.
  • Better video: Provides higher movie framerates (1080/60p versus 10800/24p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • 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.
  • Ready to shoot: Comes with an integrated lens, while the D7000 requires a separate lens.
  • More compact: Is smaller (103x60mm vs 132x105mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the D7000).
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 4 years of technical progress since the D7000 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G7X comes out slightly ahead of the D7000 (11 : 10 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.

D7000 10:11 G7X

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D7000 and the G7X in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
