Introduction
The Zeiss ZF Distagon T* 25mm f/2.8 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. Distagon lenses feature a rear-focus design (IF - inner
focusing) so the front element does not rotate. The length of the lens
remains constant regardless of the focus setting.
