Canon G7 X versus Canon G1 X Mark II

The Canon PowerShot G7 X and the Canon PowerShot G1 X Mark II are two digital cameras that were officially introduced, respectively, in September 2014 and February 2014. Both the G7X and the G1X Mark II are fixed lens compact cameras that are based on an one-inch (G7X) and an 1.5-inch sensor. The G7X has a resolution of 20 megapixel, whereas the G1X Mark II provides 13 MP.

Body comparison

An illustration of the physical size and weight of the Canon G7 X and the Canon G1 X Mark II is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. 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 G7X – represents the basis for the calculations across all the size and weight measures).

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X was launched at a somewhat lower price (by 13 percent) than the G1X Mark II, which makes it more attractive for photographers on a tight budget. 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

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. 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 features an one-inch sensor and the Canon G1 X Mark II an 1.5-inch sensor. The sensor area in the G1X Mark II is 126 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.85. The sensor in the G7X has a native 3:2 aspect ratio, while the one in the G1X Mark II offers a 4:3 aspect.

Canon G7 X and Canon G1 X Mark II sensor measures
Sensor size

Despite having a smaller sensor, the Canon G7 X offers a higher resolution of 20 megapixel, compared with 13 MP of the Canon G1 X Mark II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.49μm for the G1X Mark II). However, it should be noted that the G7X is a somewhat more recent model (by 7 months) than the G1X Mark II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

Sensor resolution

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 G7X provides substantially higher image quality than the G1X Mark II, with an overall score that is 13 points higher. This advantage is based on 1.5 bits higher color depth, 1.9 EV in additional dynamic range, 0.1 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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 G7X provides a higher frame rate than the G1X Mark II. It can shoot video footage at 1080/60p, while the G1X Mark II is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The G7X and the G1X 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 G1 X Mark II in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the G7X and the G1X Mark II have zoom lenses build in. The G7X has a 24-100mm f/1.8-2.8 optic and the G1X Mark II offers a 24-120mm f/2.0-3.9 (focal lengths in full frame equivalent terms). Hence, the G7X and G1X Mark II provide the same view at the wide-angle end, but the G1X Mark II has more tele-photo reach at the long end. The G7X offers the faster maximum aperture.

The G1X 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.

Summary

So what is the bottom line? Which of the two cameras – the Canon G7 X or the Canon G1 X Mark II – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon PowerShot G7 X:

  • More detail: Offers more megapixels (20 vs 13MP) with a 26% higher linear resolution.
  • Better image quality: Scores substantially higher (13 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.5 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.9 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
  • Faster burst: Shoots at higher frequency (6.5 vs 5.2 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).
  • More compact: Is smaller (103x60mm vs 116x74mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 249g or 45 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 7 months after the G1X Mark II).

Advantages of the Canon PowerShot G1 X Mark II:

  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Gets more shots (240 versus 210) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the G7X is the clear winner of the match-up (11 : 4 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.

G7X 11:04 G1X Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the G7X or the G1X Mark II 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. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. 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.
