Canon G9 X versus Canon G7 X Mark II

The Canon PowerShot G9 X and the Canon PowerShot G7 X Mark II are two digital cameras that were revealed to the public, respectively, in October 2015 and February 2016. Both the G9X 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 G9 X vs Canon G7 X Mark II

The side-by-side display below illustrates the physical size and weight of the Canon G9 X and the Canon G7 X Mark II. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 – the G9X – 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 notably larger (14 percent) than the Canon G9 X. Moreover, the G7X Mark II is substantially heavier (53 percent) than the G9X. In this context, it is worth noting that neither the G9X nor the G7X Mark II are weather-sealed.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G9X was launched at a somewhat lower price (by 24 percent) than the G7X Mark II, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 G9 X vs Canon G7 X Mark II

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. 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 tend to be more expensive and 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.

Technology-wise, the G7X Mark II uses a more advanced image processing engine (DIGIC 7) than the G9X (DIGIC 6), with benefits for noise reduction, color accuracy, and processing speed.

Canon G9 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 G9X 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 4 months) than the G9X, and its sensor might have benefitted from technological advances during this time.

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. 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 also of capturing video footage. 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 G9 X vs Canon G7 X Mark II

Apart from body and sensor, cameras can and do differ across a variety of features. The G9X 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 following table reports on some other key feature differences and similarities of the Canon G9 X, the Canon G7 X Mark II, and comparable cameras.

Both the G9X and the G7X Mark II have zoom lenses build in. The G9X has a 28-84mm f/2.0-4.9 optic and the G7X Mark II offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the G7X Mark II provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G9X. The G7X Mark II offers the faster maximum aperture.

Both the G9X and the G7X Mark II write their imaging data to SDXC cards.

The G7X Mark II is a recent model that features in the current product line-up of Canon. In contrast, the G9X has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G9X was succeeded by the Canon G9 X Mark II.

Review summary: Canon G9 X vs Canon G7 X Mark II

So what conclusions can be drawn? Which of the two cameras – the Canon G9 X or the Canon G7 X Mark II – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon PowerShot G9 X:

  • More compact: Is smaller (98x58mm vs 106x61mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 110g or 34 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in October 2015).


Arguments in favor of the Canon PowerShot G7 X Mark II:

  • Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 6).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Gets more shots (265 versus 220) out of a single battery charge.
  • More modern: Was introduced somewhat (4 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the G7X Mark II is the clear winner of the contest (8 : 4 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.

G9X 04:08 G7X Mark II

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G9X or the G7X Mark II. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. 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. Thus, a score needs to be put into the context of the launch date and the launch price 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
