The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon G7 X Mark III was launched in the US market at a price of $749. 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 with a 35mm slide

The size of the imaging sensor is a crucial determinant 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.

The Canon G7 X Mark III features an one-inch sensor and has a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the Canon G7 X Mark III among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

For most cameras, data on sensor performance has been reported by DXO Mark. 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 alternative cameras.

The LCD screen on the Canon PowerShot G7 X Mark III is flexibly attached to the body. In particular, the LCD can be tilted vertically to facilitate odd-angle shots in landscape orientation. This tilting design is often preferred, for example, by street photographers to a fully articulated, swivel type of LCD attachment, as it is more unobtrusive during shooting than a screen that flips out to the side.

One convenient feature of the G7X Mark III is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.

Connection 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 III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X Mark III has a microphone port. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The G7X Mark III has a zoom lens built in (8.8-36.8mm f/1.8-2.8), which, in full frame equivalent terms, provides a focal length range from 24 to 100mm. The camera is, hence, ready to shoot, while remaining more compact in size than an interchangeable lens camera with an optic that offers similar focal length and aperture specifications.

Further information on the features and operation of the G7X Mark III can be found in the free online Canon G7 X Mark III Manual or on the Canon support site.

Expert reviews

While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G7X Mark III handle or perform in practice. 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 where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
