| Manual focusing of ZF-lenses with autofocus (D)SLR cameras |
| |
If you ever tried to use classical lenses with manual focus with a digital or analog SLR camera you’ll know the problem: The standard focusing screens of modern auto focus SLR cameras are designed to show a bright, brilliant viewfinder image. Most of them, however, are lacking optical focusing aids (e.g. split/microprism screens). That makes it hard to visually judge sharpness.
However, precise and reliable focusing is required to fully utilize the capabilities of the Carl Zeiss ZF-lenses. ZF-lenses can be attached to all camera housings with F-bayonet mount; on Canon EOS camera models, for example, using an adapter.
Therefore, if ZF-lenses are used on auto focus cameras, Carl Zeiss recommends giving particular attention to the focusing screen used.
Quite a few digital and analog cameras are already well equipped. The standard focusing screens of the following camera models are well suited for manual focusing:
Canon: EOS 1D, 1D Mk II, 1 D Mk IIn, 1 Ds, 1 Ds Mk II, 1V
Nikon: D2X, D2Xs, D2H, F6
For the Canon EOS 5D, for instance, the manufacturer offers a screen with improved manual focusing characteristics (Screen Type Ee-S).
For many other popular auto focus SLRs, interchangeable focusing screens are offered by independent manufacturers. Such screens for current Nikon DSLR models are available at:
