Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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.

Sony A7R IV sensor measures

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 comparators.

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.

One feature that differentiates the A7R IV from many other 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.

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.

 

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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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.

Sony A7R IV FAQ

Below are some additional questions and answers concerning some particular features of the A7R IV.

What type of imaging sensor is used in the A7R IV?

The camera has a BSI-CMOS (Backside Illuminated Complementary Metal–Oxide–Semiconductor) sensor at its core.

Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?

Sony equipped the A7R IV with the BIONZ X image processor.

What is the ISO sensitivity range of the A7R IV?

The camera has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 50-102400.

What is the life expectancy of the shutter in the Sony Alpha A7R IV?

Sony does not publish a shutter rating for the A7R IV. Yet, shutters in comparable cameras from other manufacturers are said to be good for at least 500 000 actuations. It should be noted, though, that this number represents a Mean Time before Failure. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust an expected shutter life of 500 000 shots over, say, three years, one would have to take about 500 pictures each and every day.

Is completely silent shooting possible with the Sony A7R IV?

The camera has an electronic shutter option, so that it is indeed feasible to capture images without any shutter noise.

Do I need to purchase an external camera trigger to shoot time-lapse sequences?

No, the Sony Alpha A7R IV has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.

Is it difficult to use manual focus lenses with the Sony A7R IV?

The A7R IV offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.

Does the Sony A7R IV feature an autofocus assist light?

Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.

What is the fastest shutter speed that can be used with flash?

The A7R IV's flash sync speed is 1/250 sec.

Does the Sony A7R IV support the Ultra High Speed (UHS) bus interface for SD cards?

Yes, the camera can indeed use UHS-II cards, which provide for data transfer speed of up to 312 MB/s, in both of its card slots.

Which battery does the A7R IV use?

The camera gets its power from the NP-FZ100 (here at amazon), which is a rechargeable Lithium-Ion power pack.

Is there a vertical grip available for the A7R IV?

Yes, Sony offers the VG-C4EM as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
