Attach the Canon ProLock-i:
-insert the adapter with the locating pin lined up with the receiving slot @12 o'clock
position
-turn the locking ring CW all the way
Lens mounting:
Make sure the mount is in open position( locking lever turned all the way CCW until it
stops)
Line up the red dot on the lens with the red dot on the mount flange and insert the lens
Turn the lens clock wise until it stops.
Lightly lock the mount so the lens is still loose and try to turn the lens- it should not turn.
That means that the pin is engaged and all contacts aligned properly.
(this mounting verification is needed only initially, after a few times mounting the lens
properly becomes natural)
Press the iris “+” or “-” button momentarily until the iris opens all the way.
Now the lens is ready to use with iris control!!!
