Nikon has posted new firmware for the Coolpix 5400. This new release of firmware adds RAW file format support to the camera, this will be a significant improvement for current owners as it opens up a wide range of RAW development options as well as higher image quality. NEF files created in the Coolpix 5400 are compatible with Nikon View 6.2.2, Nikon Capture 4.1.0 and PictureProject 1.0 (or later). Installation of the firmware is fairly straightforward, just drop the 'firmware.bin' file into a firmware folder on a CF and start the camera in play mode.
