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 A6400 was launched in the US market at a price of $899. 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

The Sony A6400 features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the Sony A6400 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.

Sony A6400 sensor measures

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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.

It is notable that the A6400 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 A6400. 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 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).

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

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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 A6400 FAQ

Below are some additional questions and answers concerning some particular features of the A6400.

What type of imaging sensor is used in the A6400?

The camera is build around 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 A6400 with the BIONZ X image processor.

What is the ISO sensitivity range of the A6400?

The camera has a native sensitivity range from ISO 100 to ISO 32000.

Does the camera have a selfie-friendly screen?

Yes, the LCD-screen of the A6400 is flexible and can be turned to be front-facing for capturing selfies.

What is the life expectancy of the shutter in the Sony Alpha A6400?

Sony mentions a shutter rating of 200 000 actuations for the A6400. 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 A6400 over, say, three years, one would have to take about 200 pictures each and every day.

How do I find the shutter count on my Sony A6400?

Sony embeds the number of shutter actuations in image metadata. You can check the number of shots that your A6400 has taken up to now by uploading a recent image to the online shutter count app.

Is completely silent shooting possible with the Sony A6400?

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

Is it difficult to use manual focus lenses with the Sony A6400?

The A6400 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 A6400 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 A6400's flash sync speed is 1/160 sec.

Does the Sony A6400 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 A6400 use?

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

Where can I find the best deals for the A6400?

Grey imports from Asia, as found on eBay, are often very attractively priced. However, these cameras come without a warranty from Sony.
