The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Sony A7R IV was launched in the US market at a price of $3,499. 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 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 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. 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 associated with larger, more expensive camera bodies and lenses.

The Sony A7R IV features a full frame sensor and has a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the Sony A7R IV among the large-sensor cameras that aim for top notch image quality.

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of alternatives.

Many modern cameras cannot only take still pictures, but also record videos. The A7R IV indeed provides movie recording capabilities. The highest resolution format that the A7R IV can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R IV has an electronic viewfinder with a resolution of 5760k dots. The viewfinder offers a field of view of 100% and a magnification of 0.78x. The adjacent tables list some of the other core features of the Sony A7R IV along with similar information for a selection of comparators.

The LCD screen on the Sony Alpha A7R IV 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 feature that differentiates the A7R IV from many older cameras is in-body image stabilization (IBIS). The A7R IV reduces the risk of handshake-induced blur with all attached lenses, while cameras without IBIS have to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

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 Sony Alpha A7R IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R 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.

Further information on the features and operation of the A7R IV can be found in the free online Sony A7R IV Manual or on the Sony support site.

Expert reviews

While the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the A7R IV. 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 expert reviews are important. The adjacent 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]).

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

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
