Canon 1D X Mark II versus Canon G7 X
The Canon EOS-1D X Mark II and the Canon PowerShot G7 X are two digital cameras that were officially introduced, respectively, in February 2016 and September 2014. The 1DX Mark II is a DSLR, while the G7X is a fixed lens compact. The cameras are based on a full frame (1DX Mark II) and an one-inch (G7X) sensor. Both cameras offer a resolution of 20 megapixel. 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 1D X Mark II vs Canon G7 X
The physical size and weight of the Canon 1D X 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. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the 1DX 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 Canon G7 X is considerably smaller (77 percent) than the Canon 1D X Mark II. It is worth mentioning in this context that the 1DX 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 1DX 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 1DX Mark II and their specifications in the Canon EF Lens Catalog.
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 1DX 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 1D X Mark II vs Canon G7 X
The size of the sensor inside a digital camera is one of the key determinants 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. 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 1D X 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.
Even though the 1DX Mark II has a larger sensor, both cameras offer the same resolution of 20 megapixel. This implies that the 1DX Mark II has a lower pixel density and larger individual pixels (with a pixel pitch of 6.57μm versus 2.41μm for the G7X), which gives it a potential advantage in terms of light gathering capacity. In addition, the 1DX Mark II is a somewhat more recent model (by 1 year and 4 months) than the G7X, and its sensor might have benefitted from technological advances during this time.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 1DX Mark II provides substantially higher image quality than the G7X, with an overall score that is 17 points higher. This advantage is based on 1.1 bits higher color depth, 0.8 EV in additional dynamic range, and 2.5 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 1DX Mark II provides a higher video resolution than the G7X. It can shoot video footage at 4K/60p, while the G7X is limited to 1080/60p.
Feature comparison: Canon 1D X Mark II vs Canon G7 X
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 1DX 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 table below summarizes some of the other core capabilities of the Canon 1D X Mark II and Canon G7 X in connection with corresponding information for a sample of similar cameras.

If the number of relative strengths (bullet points above) is taken as a guide, the 1DX Mark II is the clear winner of the match-up (15 : 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.
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 1DX Mark II or the G7X. 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 hands-on reviews by experts are important.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
