Zeiss has added CPUs to its line of Nikon F-mount lenses, making them compatible with more Nikon DSLRs. The new lenses are marked as ZF.2. Users of Nikon DSLRs that don't have a NON-CPU DATA setting, such as the D3000, D5000, and D90 will now be able to meter with this new version of the Zeiss lenses. Users of Nikon DSLRs such as the D300s, D700, and D3 series will no longer have to set NON-CPU DATA lens parameters manually before taking photos.
The 18mm, 21mm, 35mm, both 50mm, and 85mm updated lenses will be available in late November. The 28mm and 100mm updates will be available in spring. The 25mm lens is being completely reworked and has no set timeframe to appear.
