The Zeiss Distagon T* 25mm f/2.8 ZF is another representative of the recently introduced ZF line-up. Just like the recently reviewed 50mm f/1.4 it is a manual focus lens compatible to the Nikon F(Ai-S)-mount (therefore ZF). On the APS-C DSLRs its field-of-view is equivalent to 37.5mm so it behaves like a very moderate wide-angle lens within this scope.

Typical for all ZF lenses the 25mm f/2.8 doesn´t feature AF nor an electronically controlled aperture. Reads: the lens has an automatic aperture but you have to stop down via the aperture ring on the lens (1/2 stop steps). Consequently the lens is not compatible to the consumer-grade Nikon DSLRs a la D40 or D70. However, it works just fine e.g. in aperture-priority mode on the D200.

The build quality of the full-metal Zeiss (brass with chromium-plated brass front bayonet) is superb. The fluted focus ring feels exceptionally well damped. The lens extends when focusing towards shorter distances.
