Camera Mounts

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).

The manually focusable ZE lenses (for EF mount) feature electronic shutter control and additional electronic contacts to the camera. All existing exposure programs (P, AV, TV, M) and the AF confirmation function of the camera are supported; lens information (focal length and speed) is passed on to the camera. Certain functions that require the use of AF lenses (various scene modes, A-DEP) are partially unavailable.

ZE lenses are compatible with the EOS camera bodies listed here, and further cameras with EF mount (e.g. cameras for cinematography). When using adapters with electronic contacts on cameras with a different mount (e.g. mirrorless system cameras, cine cameras), we cannot guarantee for the compatibility and functionality of ZE lenses. Therefore, the compatibility specifications of the adapter and the camera manufacturers have to be followed. Using ZE lenses with an adapter is at your own risk. Defects on the lens, the camera or the adapter caused by the use of an inappropriate adapter or by improper use will not be covered by our manufacturer´s warranty.

The manually focusable ZK lenses (for K mount) correspond with the KA standard. Additionally to the mechanic aperture coupling the lenses are equipped with an electronic contact pin. Furthermore, the aperture ring can be locked to the automatic mode (green “A”). Thus, all different exposure control settings (time, aperture and program mode) are possible with these camera models.

The manually focusable ZS lenses (for M-42 screw thread) are equipped with a push pin in order to close the aperture. Furthermore, they are equipped with a locking switch to change from manual to automatic aperture control. Due to this, the lens can be comfortably stopped down to working aperture when used with an adapter. The aperture priority can be used as well.

The manually focusable ZF lenses (for F mount) are equipped with the AI aperture coupling as well as the pre AI coupling. They do not include CPU coupling. Due to this, exposure metering and control is possible with all corresponding camera models. Used with camera models without AI or fork coupling the aperture is closed to the pre-selected value, but metering and automatic aperture control is not possible.
