Adobe Camera Raw 7.2 and Adobe Photoshop Lightroom 4.2 have been released and add preliminary support for Nikon D600 RAW files. The new ACR and Lightroom versions released on October 3, 2012 can read Nikon Electronic Format (NEF) files created by the Nikon D600, although it is not documented in Adobe’s release notes. Certain features such as automated profile corrections and picture controls are not yet implemented. Full support should be expected in a future release.
Update: Adobe Lightroom 4.3 and Adobe Camera Raw 7.3 are released and add official Nikon D600 support as of December 13, 2012.
Currently, full D600 RAW support is available using Capture NX2 version 2.3.4.
Lightroom 4.2 also includes new lens profiles for Nikon 24-85mm f/3.5-4.5G VR and 18-300mm f/3.5-5.6G VR as well as various bug fixes to improve usability. Support for Nikon D600 RAW files in Adobe Photoshop CS6 is available by downloading Adobe Camera Raw 7.2, which provides RAW support for additional camera models and lens profiles.
