New at Clairmont:

lenses, mirror shutter,
rotating finder, video tap, 2-200 frames,
tachometer, remote controls,
strobes, crystal sync-sound with no blimp.

We now have three types of

VistaVision camera. All
made by Wilcam; all state-ofthe-art. Ours are the W7, the W9
and the Wll. They look similar;
the one you see here is the silent-

running, sync-sound Wll.
High speed,
crystal-control
The W7 and the W9

are

variable-

speed and not silent. The W7
gives you 2 to 200 frames per sec¬
ond, crystal-controlled up to
64 fps, within 0.5% above that.
The W9 goes 2 to 100 frames,
forward and reverse; all speeds
crystal-controlled. Both cameras
have tachometer readouts, as
well as crystal-sync LEDs.

Vacuum back,
balanced movement
For best possible film flatness,
both cameras employ a vacuumback pressure plate. To minimize

vibration, the 200 fps W7 even
has a second, reciprocating
movement. It doesn't transport

position the film. It balances
the transport movement by
moving in the opposite direction.

The W9 uses six full-size regis¬
tration pins and four claws. The

W7 has six pins and eight claws.
On both cameras, the pins use
different perfs from those used

All three cameras use two 1000

magazines are horizontal, so the
film travels horizontally all

the magazines are belt-driven.
