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 Mark II was launched at a markedly lower price (by 30 percent) than the RX100 IV, which puts it into a different market segment. 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: Sony RX100 IV vs Canon G7 X Mark II

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 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of underlying technology, both cameras are build around BSI-CMOS sensors.

Sony RX100 IV and Canon G7 X Mark II sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixel. This similarity in sensor specs implies that both the RX100 IV and the G7X Mark II have the same pixel density, as well as the same pixel size. It should, however, be noted that the G7X Mark II is a somewhat more recent model (by 8 months) than the RX100 IV, and its sensor might have benefitted from technological advances during this time.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX100 IV provides a higher video resolution than the G7X Mark II. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Sony RX100 IV vs Canon G7 X Mark II

Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX100 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X Mark II relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Sony RX100 IV, the Canon G7 X Mark II, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X Mark II has a touchscreen, while the RX100 IV has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point or for making menu selections.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the RX100 IV features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the RX100 IV and the G7X Mark II have zoom lenses build in. The RX100 IV has a 24-70mm f/1.8-2.8 optic and the G7X Mark II offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Sony and Canon provide the same view at the wide-angle end, but the Canon has more tele-photo reach at the long end. Both cameras offer the same maximum aperture.

The G7X Mark II is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 IV has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX100 IV was succeeded by the Sony RX100 IV.

RX100 IV 06:04 G7X Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX100 IV and the G7X Mark II in practical situations. 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 why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 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.
