The Legendary Wide-angle Lens with Close-focus Capability
This wide-angle lens is the most advanced version of the legendary Distagon, a high performance lens with close focus capabilities, that was first introduced in 1961. The Distagon T* 2,8/25 is a recalculation of this design for use with modern SLRs and DSLRs using either full-frame or smaller sensors. The close-focus capability increases the versatility of this lens, providing a wider perspective than the usual macro focal lengths. Combined with a digital SLR with a 1.5 crop factor, the lens has an effective focal length of 38 mm and becomes a moderate wide-angle lens. The Distagon T* 2,8/25 is available with the F bayonet (ZF), K bayonet (ZK) and M42 (ZS) lens mounts and is ideally suited for nature and landscape photography or for any situation requiring a wider perspective.
ZF.2: SLR lenses with F bayonet mount for cameras from Nikon
ZF.2 lenses support all key modes (e.g. aperture priority, shutter priority, program AE or manual exposure settings) on camera models equipped with an electronic interface (e.g. current Nikon DSLR cameras). To do so, simply lock the aperture ring in the largest f-stop (e.g. 16) shown in orange.
On camera models without an electronic interface, the aperture is manually set on the lens aperture ring. With some camera models, it is possible to set in the menu whether the lens should be selected using the setting dial on the camera or the aperture ring on the lens.
Please note that, for technical reasons, there is no halfway notch between the largest (e.g. 16) and second largest (e.g. 11) f-stop. The focused distance is not transmitted to the camera body. For details regarding metering modes and further functions, please check the camera´s manual. The ZF.2 lenses accord to the Nikon AI-P standard (manual focus lenses with CPU).
