The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Sony RX10 IV was launched in the US market at a price of $1,699. 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 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.
The Sony RX10 IV 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 Sony RX10 IV among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The RX10 IV indeed provides movie recording capabilities. The highest resolution format that the RX10 IV can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX10 IV has an electronic viewfinder with a resolution of 2359k dots. The viewfinder offers a field of view of 100% and a magnification of 0.70x.

One convenient feature of the RX10 IV 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.
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 Sony Cyber-shot DSC-RX10 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX10 IV 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 RX10 IV has a zoom lens built in (8.8-220mm f/2.4-4.0), which, in full frame equivalent terms, provides a focal length range from 24 to 600mm. 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.
While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX10 IV 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 why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]).

The above review scores should be interpreted 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 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.
