I’m a bit late with this but Nikon has made a firmware upgrade available for the D2H. When they further developped the D2H firmware for the new D2X, they found a few issues and thought of a few enhancements — a 12mpix cam requires really BIG memory cards as you know. If you read till this far — I was joking about the D2X, but all the features below in the upgrade are true!
The firmware has 2 parts (like the D70 firmware update) — A and B. Both version go from 1.0 to 2.0.
This update is not only a bug fix but has a major number of improvements. Most important are:
Further are Autofocus and Auto white balance performance improved. A problem has been fixed which caused the frame rate in continuous shooting to decrease when sensitivity was not raised automatically when ‘ISO auto’ was turned On.
