BEAULIEU 4008 - Framing and Focussing

lenses (see below). The Beaulieu's reflex cell, which lies behind
the lens, gives accurate data no matter what the optical equipment: it
is thus possible, with 4008 ZM or S cameras, to use any "C-mount
cine lenses, most still miniature camera lenses, and all filters.
Correction is automatic.
9° Framing and focussing
The viewfinder eyepiece being once for all adjusted to the ope-
rator's eyesight, the subject should be sharp on the screen, for the
image viewed is that which will be filmed. To achieve this, all that
need be done is to rotate the lens focussing ring until the image on
the screen is in perfect focus. It is necessary that this adjustment
be made at maximum aperture and with the focal-length adjustment
in the "telephoto” position with the 4008 ZM, in order to obtain both
these positions simultaneously, just depress button V to maximum
depth.
With the 4008 S, it is the push switch placed at the tip of the Reglo-
matic mechanism which operates the diaphragm's opening to full
aperture and the focal-length setting ring has to be operated manually
to set the "telephoto” position (33).
Once this adjustment has been made, any focal lengths (set by elec-
tric or manual control) can be used without having to adjust the
focus.
10° Use of the electric zoom (4008 Zm camera)
The focal length adjustment device (zoom) on the Beaulieu 4008 ZM
is electrically actuated. Passage from wide-angle position to tele-
photo position, and vice versa, is simply effected by pressing on
Switch O or switch O' (34).
Switch O drives the lens towards the telephoto position.
