Canon G7 X Mark II versus Nikon D3400

The Canon PowerShot G7 X Mark II and the Nikon D3400 are two digital cameras that were revealed to the public, respectively, in February 2016 and August 2016. The G7X Mark II is a fixed lens compact, while the D3400 is a DSLR. The cameras are based on an one-inch (G7X Mark II) and an APS-C (D3400) sensor. The Canon has a resolution of 20 megapixel, whereas the Nikon provides 24 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: Canon G7 X Mark II vs Nikon D3400

The physical size and weight of the Canon G7 X Mark II and the Nikon D3400 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 dimensions 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 side – the G7X Mark II – 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 D3400 is considerably larger (88 percent) than the Canon G7 X Mark II. In this context, it is worth noting that neither the G7X Mark II nor the D3400 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G7X Mark II has a lens build in, whereas the D3400 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 D3400 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the G7X Mark II gets 265 shots out of its NB-13L battery, while the D3400 can take 1200 images on a single charge of its EN-EL14a 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. 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: Canon G7 X Mark II vs Nikon D3400

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G7 X Mark II features an one-inch sensor and the Nikon D3400 an APS-C sensor. The sensor area in the D3400 is 216 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G7 X Mark II and Nikon D3400 sensor measures

With 24MP, the D3400 offers a higher resolution than the G7X Mark II (20MP), but the D3400 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the G7X Mark II) due to its larger sensor. Moreover, the D3400 is a somewhat more recent model (by 5 months) than the G7X Mark II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the D3400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

So what conclusions can be drawn? Is the Canon G7 X Mark II better than the Nikon D3400 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Canon PowerShot G7 X Mark II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Comes with a build-in lens, while the D3400 requires a separate lens.
  • More compact: Is smaller (106x61mm vs 124x98mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the D3400).
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More heavily discounted: Has been on the market for longer (launched in February 2016).

ilogo

Arguments in favor of the Nikon D3400:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Makes it possible to change lenses and thus to use specialty optics.
  • Longer lasting: Gets more shots (1200 versus 265) out of a single battery charge.
  • More modern: Was introduced somewhat (5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the G7X Mark II emerges as the winner of the contest (10 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

G7X Mark II 10:08 D3400

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G7X Mark II or the D3400 handle or perform in practice. 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, 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 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.
