Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G7 X Mark II and the Canon PowerShot G1 X? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon G7 X Mark II and the Canon G1 X. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon G1 X is considerably larger (47 percent) than the Canon G7 X Mark II. Moreover, the G1X is substantially heavier (67 percent) than the G7X Mark II. In this context, it is worth noting that neither the G7X Mark II nor the G1X are weather-sealed.

Concerning battery life, the G7X Mark II gets 265 shots out of its Canon NB-13L battery, while the G1X can take 250 images on a single charge of its Canon NB-10L power pack. The power pack in the G7X Mark II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X Mark II 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

The size of the sensor inside a digital camera is one of the key determinants 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G7 X Mark II features an one-inch sensor and the Canon G1 X an 1.5-inch sensor. The sensor area in the G1X 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 Mark II has a native 3:2 aspect ratio, while the one in the G1X offers a 4:3 aspect.

In terms of chip-set technology, the G7X Mark II uses a more advanced image processing engine (DIGIC 7) than the G1X (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the Canon G7 X Mark II offers a higher resolution of 20 megapixels, compared with 14.2 MP of the Canon G1 X. 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 4.30μm for the G1X). However, it should be noted that the G7X Mark II is much more recent (by 4 years and 1 month) than the G1X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon G7 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X Mark II 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 are 21.8 x 16.3 inches or 55.3 x 41.5 cm for good quality, 17.4 x 13.1 inches or 44.2 x 33.2 cm for very good quality, and 14.5 x 10.9 inches or 36.8 x 27.6 cm for excellent quality prints.

The Canon PowerShot G7 X Mark II has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Canon PowerShot G1 X are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the G7X Mark II is build around a BSI-CMOS sensor, while the G1X uses a 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 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G7X Mark II provides a higher frame rate than the G1X. It can shoot video footage at 1080/60p, while the G1X is limited to 1080/24p.

Feature comparison

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 Mark II relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon G7 X Mark II and Canon G1 X along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark II has a touchscreen, while the G1X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Canon G7 X Mark II has 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 G7X Mark II and the G1X have zoom lenses built in. The G7X Mark II has a 24-100mm f/1.8-2.8 optic and the G1X offers a 28-112mm f/2.8-5.8 (focal lengths in full frame equivalent terms). Hence, the G7X Mark II provides a wider angle of view at the short end than the G1X, but less tele-photo reach at the long end. The G7X Mark II offers the faster maximum aperture.

Concerning the storage of imaging data, both the G7X Mark II and the G1X write their files to SDXC cards. The G7X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1X cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 G7 X Mark II and Canon PowerShot G1 X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark II offers wifi support, while the G1X does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the G7X Mark II and the G1X have been discontinued, but can regularly be found used on ebay. The G1X was replaced by the Canon G1X Mark II, while the G7X Mark II was followed by the Canon G7 X Mark III. Further information on the features and operation of the G7X Mark II and G1X can be found, respectively, in the Canon G7 X Mark II Manual (free pdf) or the online Canon G1 X Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon G7 X Mark II and the Canon G1 X? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Canon PowerShot G7 X Mark II:

• More detail: Offers more megapixels (20 vs 14.2MP) with a 21% higher linear resolution.
• Better jpgs: Has a more modern image processing engine (DIGIC 7 vs DIGIC 5).
• Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (8 vs 1.9 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (106x61mm vs 117x81mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 215g or 40 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
• More modern: Reflects 4 years and 1 month of technical progress since the G1X launch.

Arguments in favor of the Canon PowerShot G1 X:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• 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.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been around for much longer (launched in January 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the G7X Mark II is the clear winner of the match-up (17 : 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 G7 X Mark II and the Canon G1 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 G7X Mark II and the G1X 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.

Expert reviews

This is why hands-on reviews by experts are important. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted 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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
