Canon G7 X versus Canon G7 X Mark II

The Canon PowerShot G7 X and the Canon PowerShot G7 X Mark II are two digital cameras that were officially introduced, respectively, in September 2014 and February 2016. Both the G7X and the G7X Mark II are fixed lens compact cameras that are equipped with an one-inch 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 G7 X vs Canon G7 X Mark II

The side-by-side display below illustrates the physical size and weight of the Canon G7 X and the Canon G7 X Mark II. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 – the G7X – 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 Mark II is somewhat larger (5 percent) than the Canon G7 X. Moreover, the G7X Mark II is markedly heavier (5 percent) than the G7X. In this context, it is worth noting that neither the G7X nor the G7X Mark II are weather-sealed.

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 two cameras under review were launched at the same price and fall into the same market segment. 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 G7 X vs Canon G7 X Mark II

The size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon G7 X and Canon G7 X Mark II sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixel. This similarity in sensor specs implies that both the G7X and the G7X Mark II have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7X Mark II is a somewhat more recent model (by 1 year and 5 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"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

 

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

Apart from body and sensor, cameras can and do differ across a variety of features. The G7X and the G7X Mark II are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Canon G7 X and Canon G7 X Mark II in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the G7X and the G7X Mark II have zoom lenses build in. Both optics have identical focal length range and aperture specifications (8.8-36.8mm f/1.8-2.8). Both cameras offer the same maximum aperture.

The G7X 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 G7 X vs Canon G7 X Mark II

So what conclusions can be drawn? Which of the two cameras – the Canon G7 X or the Canon G7 X Mark II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon PowerShot G7 X:

  • More heavily discounted: Has been on the market for longer (launched in September 2014).


Reasons to prefer the Canon PowerShot G7 X Mark II:

  • Faster burst: Shoots at higher frequency (8 vs 6.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (265 versus 210) out of a single battery charge.
  • More modern: Was introduced somewhat (1 year and 5 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G7X Mark II emerges as the winner of the match-up (3 : 1 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.

G7X 01:03 G7X Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G7X and the G7X Mark II 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 where reviews by experts come in.

The review scores listed above should be treated with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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, please note that some of the review sites have changed their methodology and reporting over time.
