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 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.
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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G1 X Mark II features an 1.5-inch sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X is 56 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 2.7. The sensor in the G1X Mark II has a native 4:3 aspect ratio, while the one in the G7X offers a 3:2 aspect.
Despite having a smaller sensor, the G7X offers a higher resolution of 20 megapixels, compared with 13 MP of the G1X Mark II. This megapixels 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.
The resolution advantage of the Canon G7 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon G1 X Mark II are 20.8 x 15.6 inches or 52.8 x 39.6 cm for good quality, 16.6 x 12.5 inches or 42.3 x 31.7 cm for very good quality, and 13.9 x 10.4 inches or 35.2 x 26.4 cm for excellent quality prints.
The Canon PowerShot G1 X Mark II has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Canon PowerShot G7 X are ISO 125 to ISO 12800 (no boost).
In terms of underlying technology, the G1X Mark II is build around a CMOS sensor, while the G7X uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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 consideration, the G7X offers substantially better image quality than the G1X Mark II (overall score 13 points higher). The advantage is based on 1.5 bits higher color depth, 1.9 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the G7X provides a faster frame rate than the G1X Mark II. It can shoot movie footage at 1080/60p, while the G1X Mark II is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The G1X Mark II and the G7X 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. That said, the G1X Mark II can be equipped with an optional viewfinder – the EVF-DC1. The adjacent table lists some of the other core features of the Canon G1 X Mark II and Canon G7 X along with similar information for a selection of comparators.

The Canon G1 X Mark II and the Canon G7 X both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Both the G1X Mark II and the G7X have zoom lenses built in. The G1X Mark II has a 24-120mm f/2.0-3.9 optic and the G7X offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the G1X Mark II and G7X provide the same view at the wide-angle end, but the G7X has less tele-photo reach at the long end. The G7X offers the faster maximum aperture.
Concerning the storage of imaging data, both the G1X Mark II and the G7X write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G1 X Mark II and Canon PowerShot G7 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark II has a hotshoe, while the G7X does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the G1X Mark II and the G7X have been discontinued, but can regularly be found used on ebay. The G1X Mark II was replaced by the Canon G1 X Mark III, while the G7X was followed by the Canon G7 X Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what conclusions can be drawn? Is there a clear favorite between the Canon G1 X Mark II and the Canon G7 X? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot G1 X Mark II:
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Longer lasting: Can take more shots (240 versus 210) on a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been on the market for longer (launched in February 2014).
Advantages of the Canon PowerShot G7 X:
- More detail: Has more megapixels (20 vs 13MP), which boosts linear resolution by 26%.
- Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
- Better video: Provides higher movie framerates (1080/60p versus 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 will fit more readily into a bag.
- Less heavy: Has a lower weight (by 249g or 45 percent) and is thus easier to take along.
- More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
- More modern: Was introduced somewhat (7 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the G7X is the clear winner of the contest (11 : 6 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon G1 X Mark II and the Canon G7 X place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G1X Mark II and the G7X in practical situations. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, 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 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.
