Fine Ratio Focus Gearing
The Fine Ratio Focus Gearing 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.
Fine Ratio Focus Gearing can be added to every Actus-B, Actus-G and Actus-DB version ever delivered, by a simple replacement routine.
Next to the focus movement, the Fine Ratio Focus Gearing is also suitable to replace the Tilt movement on the front standard of the Actus-B series in the same way.
