Canon 6D Mark II versus Canon G7 X

The Canon EOS 6D Mark II and the Canon PowerShot G7 X are two digital cameras that were officially introduced, respectively, in June 2017 and September 2014. The 6D Mark II is a DSLR, while the G7X is a fixed lens compact. The cameras are based on a full frame (6D Mark II) and an one-inch (G7X) sensor. The 6D Mark II has a resolution of 26 megapixel, whereas the G7X 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: Canon 6D Mark II vs Canon G7 X

The physical size and weight of the Canon 6D Mark II and the Canon G7 X are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size 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 – the 6D Mark II – 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 (61 percent) than the Canon 6D Mark II. It is worth mentioning in this context that the 6D Mark II 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 6D Mark II 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 6D Mark II and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 6D Mark II gets 1200 shots out of its LP-E6N battery, while the G7X can take 210 images on a single charge of its NB-13L power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X was launched at a lower price than the 6D Mark II, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 6D Mark II 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 6D Mark II features a full frame sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 6D Mark II and Canon G7 X sensor measures

With 26MP, the 6D Mark II offers a higher resolution than the G7X (20MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 2.41μm for the G7X) due to its larger sensor. Moreover, the 6D Mark II is a somewhat more recent model (by 2 years and 9 months) than the G7X, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

6D Mark II 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 6D Mark II provides substantially higher image quality than the G7X, with an overall score that is 14 points higher. This advantage is based on 1.4 bits higher color depth, 0.8 EV of lower dynamic range, and 2.4 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Canon 6D Mark II vs Canon G7 X

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 6D Mark II 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 adjacent table lists some of the other core features of the Canon 6D Mark II and Canon G7 X along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The 6D Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the G7X has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G7X was succeeded by the Canon G7 X Mark II.

Review summary: Canon 6D Mark II vs Canon G7 X

So what is the bottom line? Is the Canon 6D Mark II better than the Canon G7 X or vice versa? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS 6D Mark II:

  • More detail: Offers more megapixels (26 vs 20MP) with a 14% higher linear resolution.
  • Better image quality: Scores substantially higher (14 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.4 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (2.4 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (1200 versus 210) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More modern: Reflects 2 years and 9 months of technical progress since the G7X launch.


Arguments in favor of the Canon PowerShot G7 X:

  • More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
  • Ready to shoot: Comes with an integrated lens, while the 6D Mark II requires a separate lens.
  • More compact: Is smaller (103x60mm vs 144x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the 6D Mark II).
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • 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 heavily discounted: Has been around for much longer (launched in September 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the 6D Mark II is the clear winner of the match-up (12 : 8 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.

6D Mark II 12:08 G7X

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 6D Mark II or the G7X. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
