5.1.5 Operating the WFU-1 / WFU-3
(Wireless Focus Unit)
The WFU-3 is a redesign of the WFU-1 and offers additionally
the free adjustment of the index marking within a range
of 180°. WFU-1 and WFU-3 are fully compatible in their
functions and can be attached to all WMUs.
With a WFU, the focus and iris rings can be controlled
remotely. It is however also possible to control focus with
one WFU and iris with a second WFU. In this case each
WFU must be operated with its own WMU, or must be
attached to a WMU-3 using the WEB-3 Expansion bracket.
The WFU has two main operating elements:
a handwheel ➪ photo with stops ➪ photo and a slider
➪ photo. With the switch on the front side of the WFU it
is possible to determine whether focus or iris is to be
controlled with the handwheel. The slider then controls the
remaining lens ring.
If two WFU units are used for focus and iris, for each WFU
a separate WMU, or a WMU-3 with WEB-3 is necessary.
Before switching on both WMUs, the WFU switches must
be set to different positions. In this case only the two
handwheels are used for control; the sliders are deactivated.
