Canon G1 X versus Canon G7 X
The Canon PowerShot G1 X and the Canon PowerShot G7 X are two digital cameras that were officially introduced, respectively, in January 2012 and September 2014. Both the G1X and the G7X are fixed lens compact cameras that are based on an 1.5-inch (G1X) and an one-inch (G7X) sensor. The G1X has a resolution of 14.2 megapixel, whereas the G7X provides 20 MP. 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 G1 X vs Canon G7 X
The physical size and weight of the Canon G1 X and the Canon G7 X are illustrated 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. 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 G1X – represents the basis or 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 is considerably smaller (35 percent) than the Canon G1 X. Moreover, the G7X is substantially lighter (43 percent) than the G1X. In this context, it is worth noting that neither the G1X nor the G7X 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 G7X was launched at a somewhat lower price (by 13 percent) than the G1X, 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: Canon G1 X vs Canon G7 X
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G1 X 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 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 megapixel, compared with 14.2 MP of the G1X. 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 4.30μm for the G1X). However, it should be noted that the G7X is much more recent (by 2 years and 8 months) than the G1X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 consideration, the G7X offers substantially better image quality than the G1X (overall score 11 points higher). The advantage is based on 1.3 bits higher color depth, 1.9 EV in additional dynamic range, 0.2 stops of reduced 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G7X provides a faster frame rate than the G1X. It can shoot movie footage at 1080/60p, while the G1X is limited to 1080/24p.
Feature comparison: Canon G1 X vs Canon G7 X
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G1X 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 adjacent table lists some of the other core features of the Canon G1 X and Canon G7 X along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the G1X and the G7X have zoom lenses build in. The G1X has a 28-112mm f/2.8-5.8 optic and the G7X offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the G7X provides a wider angle of view at the short end than the G1X, but less tele-photo reach at the long end. The G7X offers the faster maximum aperture.
Both the G1X and the G7X have been discontinued, but can regularly be found used on eBay. The G1X was replaced by the Canon G1X Mark II, while the G7X was followed by the Canon G7 X Mark II.

If the count of relative strengths (bullet points above) is taken as a measure, the G7X is the clear winner of the contest (14 : 5 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 G1X or the G7X. 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
