We’ve started shipping the AC-380 and AC-381 fine ratio gears for the Actus. It comes with a printed instruction manual and the required allen key.
It’s easy to install. For your convenience we’ve uploaded a video:
The new dual knob design allows for both standard and reduced gearing. The larg knob changes the settings as you’re used to, whilst the smaller knob offers a 1:5 reduction. This enables more precise focussing and tilting.
AC-380 is used on Actus-B’s front and rear standard. The front standard of the Actus-G, Actus-GFX and Actus-DB2 requires AC-381.
Because of the differences in tilt mechanism design, two versions of this upgrade will be offered. The AC-380 is for focus on all Actus cameras and for the tilt movements of the Actus-Mini. The AC-381 upgrades the tilt movements on the Actus-G or Actus-DB II. Both are available individually, for users that wish to upgrade one knob.
