Now carefully rotate the wheel in either direction. It is not important which limit you set first. Constantly
observe the lens as you rotate the wheel. Carefully approach the last mark on the lens and stop on the mark.
If the motor is humming or chattering, wind back a little bit until it stops.
Set the limit by pressing the appropriate limit button. The button to use is the one you have turned the
wheel towards.
Wind the wheel back towards the other end of the lens and repeat this process.
Test the range of motion by carefully moving the lens through its range of motion, checking there is no
humming or chattering at either end.
If the control wheel operates in the wrong direction, reverse this by flicking the direction switch on top of
the transmitter unit.
Some long focal length lenses have a longer lens throw (turn of the lens barrel from infinity to close focus. In
some cases, this can be too much travel for the Proaim motor to turn all the way.
In these situations, there are several things you can do to help achieve full lens barrel movement. If using an
SLR lens, the lens gears you are using will have a big impact on the rotation you can achieve. The fewer the
teeth on the lens, the better. The gears are ideal as they hug the lens barrel tightly so the number of teeth is
minimal.
If you decide that full turn on the lens is not necessary, it is possible to pull focus using just part of the focus
movement. Based on the individual shot you are working on, decide which end of the focus scale is more
important, infinity or close. In most cases, this will be infinity.
