The CA-905K/905F Large Lens Adaptor enables the
attachment of a studio lens to a portable color video
camera (referred herein as “camera”), and is designed
for use on a camera that is connected to a CA-590/
590P Camera Adaptor for Triax transmission. The
CA-905K/905F accepts the attachment of an optional
5-type viewfinder, or an optional 7-type viewfinder
when the optional BKP-9057 Viewfinder Saddle is
used.
Features
Compatible with Sony specification Large
-lens
The unit allows you to attach Sony hanger-type large-
lenses. It is compatible with both full servo-control
and manual control lenses. You can also use a
portable lens (with extender only).
Easy to assemble and disassemble
Once you have done the initial lens and camera
alignment, you need not repeat the alignment each
time you attach the lens and camera. The BKP-9057
employs a saddle rotation function which makes it
easy to attach and detach the camera.
Lightweight and space-saving system
The CCU-590/590P (portable CCU) enables the use of
a large lens. Further savings in weight and space is
possible by using a 5-type viewfinder.
Seven-type viewfinder (available when the
BKP-9057 is installed)
By installing the optional BKP-9057 viewfinder saddle
to the unit, you can use a 7-type B/W viewfinder and a
7-type color viewfinder.
Overview
Studio-use-camera-type control panel
The rear control panel provides almost all the
functions of the color video camera for studio use. It
thus allows you to operate the unit (when used to
connect a large lens to the camera) as you would a
studio camera.
By installing the BKP-9057, the Picture-In-Picture
function can also be used. Note, however, that the
Picture-In-Picture function cannot be used with certain
cameras.

supply and the outer sheath for safety ground.
For your safety, do not use a triaxial cable whole inner
and outer sheaths are short-circuited. Use of such a
cable will cause electric shock.

is also possible with the switch set to NORMAL.
5Remove the lens cap.
Attaching the Camera
The explanations in this manual use the BVP-E30/
E30P/E30WS/E30WSP as an example. The positions
of the VF connector and lens connector on the certain
cameras differ from those on the BVP-E30/E30P/
E30WS/E30WSP.
Preparing the camera
1If the BKP-9057 viewfinder saddle is attached to
the CA-905K/905F, turn the saddle lock knob
counterclockwise to loosen it, then tilt the saddle
backward.
2Remove the 1.5-type viewfinder.
Push the viewfinder slide inward.
3Turn the lens locking lever upward and remove the
lens mount cap.
Aligning the camera mount
After you have aligned the camera mount once, you
need not align it again if the same camera model is
used.
1Slide the slide lever to LOCK.
2Insert the V-wedge shoe on the base of the camera
into the V-shaped groove on the camera mount,
and slide the camera forward until it clicks in
place.
