Here's a rundown of other changes:The autofocus module has been updated to perform faster and with greater precision.
A new Li-ion battery, the 2500 mAh EN-EL4a, replaces the 1900 mAh EN-EL4 battery used in the D2x. The new battery boosts CIPA battery life rating from 2,600 shots to 3,800 shots, and will be backward-compatible with any Nikon using the older EN-EL4.
The rear LCD monitor, though remaining 2.5 inches, is now the newer screen used on the Nikon D200, with its wider (170-degree) viewing angle.
The image buffer has been increased; the maximum number of highest-quality JPEGs that can be captured in a continuous burst from 35 to 60.
Encrypted image authentication data can be stored with image files using any type of compatible card.
Recorded images can be downsized in camera for easier e-mailing or transmission.
ISO settings above 800 can be set in 1/3-EV increments.
A black-and-white image capture mode has been added.
The autofocusing lock-on (which holds the focus within an AF area if distance changes markedly) can now be adjusted to hold for varying intervals of time, rather than be just on or off as on the D2x.
The D2xs can upload three custom image tone curves rather than just one.
