The Zeiss 25mm f/2.8 Distagon T received its expected ZF.2 upgrade. This basically takes it from being an AI-S compatible lens (exposure works on any Nikon DSLR with CPU Lens Data function) to a P-type lens (exposure works on any modern Nikon body). This is no big deal for D300, D700, and D3 series users, but D3000 through D90 users now will find this lens a better match to their camera.
