Nikon Europe has today announced new firmware for the D100 (ver 2.00) and D1X / D1H (ver 1.10). Both firmware upgrades contain some common elements such as embedded ICC profiles for Adobe RGB images and support for Lexar Media Pro 'Write Acceleration' technology. The D100 upgrade adds support for PTP USB connections, the D1X / D1H upgrade adds EXIF 2.2 support, better battery power detection and additional lens information in EXIF headers. Firmware upgrades will be carried out free of charge although you will have to return the camera to your nearest Nikon Support Facility.
