Nikon have released the first firmware update (version 1.10) for the flagship D3 DSLR.

The following changes have been made in version 1.10:

Modifications Enabled with upgrade of A and B firmware from ver. 1.00 to ver.1.10

• A "Vignette Control" item has been added to the "Shooting Menu".
• A focus point brightness item has been added to the "a6: Focus point illumination" setting in the "Autofocus" category in the "Custom Settings".
• The "Highlights" playback display option has been moved from "Display mode > Basic photo info > Highlights" in the playback menu to "Display Mode > Detailed photo info > Highlights".
• When shutter speed and/or aperture are locked when shooting in LiveView mode, using the "L" (command lock) button, an "L" icon is now displayed in the camera monitor.
• The size and color of "Demo" displayed in the monitor with playback, when "No memory card?" in the "Custom Settings" is set to "Enable Release", have been modified.
• The range of settings available for "ISO sensitivity settings > ISO sensitivity auto control > Minimum shutter speed" in the Shooting Menu has been increased from 1/250th – 1s to 1/4000s – 1s.
• When a compatible Speedlight or Wireless Speedlight Commander is used, the AF assist illuminator now lights regardless of focal length.
• When shooting in hand-held LiveView mode and the frame is magnified prior to autofocusing, operation has been modified so that display returns to the magnified display rather than full-frame display.
• In some rare cases, white balance was not accurately calculated for images captured at a shutter speed of around 1/4s in P and A exposure modes. This issue has been resolved.
• When attempting to crop images at an aspect ratio of 4:3 using the "Trim" option in the "Retouch" menu, the cropped image did not have an accurate 4:3 aspect ratio. This issue has been resolved.
