The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Sony A7R was launched in the US market at a price of $2,299. 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 more expensive and lead to bigger and heavier cameras and lenses.

The Sony A7R 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 among the large-sensor cameras that aim for top notch image quality.

Sony A7R sensor measures

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

It is notable that the A7R 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 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 A7R in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Notes: ++) 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.

Sony A7R FAQ

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

What is the technology behind the imaging sensor in the A7R?

The camera features a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.

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 with the BIONZ X image processor.

What is the ISO sensitivity range of the A7R?

The camera has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-51200.

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

Sony mentions a shutter rating of 250 000 actuations for the A7R. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the A7R over, say, three years, one would have to take about 250 pictures each and every day.

How do I find the shutter count on my Sony A7R?

Sony embeds the number of shutter actuations in image metadata. You can check the number of shots that your A7R has taken up to now by uploading a recent image to the online shutter count app.

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

The A7R 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 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's flash sync speed is 1/160 sec.

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

Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).

Which battery does the A7R use?

The camera gets its power from the NP-FW50 (here at amazon), which is a rechargeable Lithium-Ion power pack.

Is there a vertical grip available for the A7R?

Yes, Sony offers the VG-C1EM as an optional accessory to facilitate shooting in portrait orientation and to provide additional battery power.
