Nikon has issued firmware updates for its professional and semi-professional DSLR cameras.
The full-frame D800 and D800E SLRs are being updated with new firmware that improves continuous autofocus (AF-C), improvements to live view and Adobe RGB image display, and reliability improvements.
The D4 receives a fix to its auto white balance and to image sharpness, as well as reliability improvements.
The lower-cost full-frame D600 also receives the focus improvements and fixes to colour temperature, as well as other maintenance fixes.
But the most significant change is to increase the clean video output over HDMI to 100 per cent of the image. Previously, the D600’s clean (or “information off” output) was limited to 95 per cent of the image, causing a loss of resolution or cropping, when recording to an external device such as a Nanoflash, Sound Devices’ PIX or Atomos Ninja.
The majority of Nikon DSLRs have also been updated so that they will work with the company’s 800mm f5.6 Nikkor telephoto lens.
