Sony's Alpha 7 II camera is a full-frame digital camera with interchangeable lenses. Being a mirrorless camera, the company has made an announcement to improve the device's functionality via updating its firmware.

The Sony Alpha 7 II is a mirrorless camera that features a strong lens system, excellent image quality and very striking price point. To improve the camera's functions, the company will be releasing a firmware update that should make present device owners pleased and future owners fascinated.

The firmware update will be adding sensor-phase autofocus support for camera lenses mounted through an adapter. Also, this update will support not only Sony Alpha SLR lenses but also Minolta's and Canon EF lenses through third party adapters. In addition, a Chinese-made Nikon autofocus adapter was teased by Sony earlier this year but is not available as of the moment.

The advantages of SLR lenses focusing using sensors rather than adapters that have built-in phase detection sensors is that there is no need to make adjustments to focus settings for the lenses to capture images perfectly. With its autofocus system, the lenses will automatically adjust for its users.

While there are pros, there are also cons. With the camera using autofocus adapters, the camera tends to "hunt" subjects to lock on. This makes autofocusing extend time, though less than 10 seconds.

For the first time in Sony digital camera history, the Alpha 7 II has adapted lenses support and enthusiasts expect it to get better with the company's future camera lineup. With regard to the firmware update, it now supports uncompressed 14-bit raw images. Previously, the camera was limited at shooting compressed raw format but most photographers probably have not noticed the difference aside from large file formats.

With the latest firmware update on Sony's Alpha 7 II, the halo effects are reduced and less noise during autofocus is produced. The firmware will be publicly released on Nov. 18 and it can be downloaded for free.
