4. Adjusting the AC-380 Focus knob
To fix the AC-380 in position, take the barrel of the knob and rotate it
counter clockwise while keeping pressure on the knob towards the
Actus. Use the supplied 2mm Allen key to retighten the focus knob
locking screw and tighten it firmly.
Note:
The barrel of the AC-380 is eccentric and you can adjust the feel of the
knob until it meets your demands. To adjust the knob repeat the steps
noted above and keep in mind that rotating the barrel counter clockwise
applies more pressure to the rail resulting in a stiffer knob, and rotating
the barrel clockwise will release pressure on the rail.
