Nikon D7000 firmware version 1.02 changes the behavior of the camera's long exposure noise reduction function, which when enabled will now apply dark current subtraction to images with shutter speeds greater than one second, rather than the previous eight second threshold. Nikon has also tweaked its movie output so as to correct an issue with unspecified movie editing software failing to recognize D7000 video clips. A further video-related issue that has been corrected relates to the audio portion of movie clips playing at reduced volume or playing intermittently, if the same clip was watched multiple times in a row.
The D7000's image overlay function had an issue whereby Raw images shot using the function whose white balance was fine-tuned in Capture NX 2 or ViewNX 2 would show a magenta color cast, and this problem too has been fixed. A further tweak to interaction with the GP-1 GPS device sees the D7000 now correctly display the heading as ---.--, rather than 0.00”. Nikon has also fixed display errors in its viewfinder Virtual Horizon function, noticeable when the role was assigned to the Function or Preview buttons. Finally, a couple of Help display errors have been corrected.
