The AC-380 is a replacement focus assembly for the Actus camera bodies, with the unique ability to drive the focus movement in normal ratio as well as with a fine ratio of 1:5, allowing very precise focussing in all situations. The extra focus layer knob has a larger diameter for optimum feeling of fine focus.

AC-380 can be added to every Actus-B, -G and -DB version ever delivered, by a simple replacement routine.

Next to the focus movement, the AC-380 is also suitable to replace the Tilt movement on the front standard of the Actus-B series in the same way.  

AC-380 consist of an assembly of the drive gear, direct drive knob and a fine ratio knob.

AC-380 is a replacement assembly suitable for the focus of all delivered Actus-B, Actus-G and Actus-DB versions including Actus-GFX, -XCD, and -DB2.

AC-380 can also be used in the same way for replacement of the Tilt knob assembly on the front standard of the Actus-B and early Actus-DB, adding a fine ratio tilt functionality.
