Following the lead of the a7S II and a7R II, Sony’s a7 II Mirrorless Digital Camera will be receiving uncompressed raw via a firmware update, set to be released on November 18. This option provides users with the choice between smaller file sizes via compression or the retention of as much image data as possible for advanced raw file development. Along with this, the camera’s AF system sees a massive boost in performance with the 117-point on-sensor phase detection AF array now supporting adapted lenses, such as those from Sony’s A-mount line. This is similar to what we have already seen with the a7R II and ensures fast, accurate autofocus performance with a vast variety of glass, making the move to mirrorless much easier. Additionally, Sony is adding more customization options to the camera, allowing movie recording to be assigned to a custom key.
