ARRI ARRIFLEX 235 User Manual

If the mechanical iris is closed more than necessary, the 

IVS will compensate by increasing the gain and improve 

the image brightness electronically. This creates additional 

electronic noise. To avoid this, open the mechanical iris.

•  To change the iris, turn the wheel with the iris symbol Õ.

The position of the image on the CCD-Chip and its focus 

can vary slightly from camera to camera. The video 

image on the monitor may appear not centered, rotated 

or out of focus.

All settings can be made by using a 1,5 mm allen key, 

which is delivered with the IVS.

•  Image position adjustments in x- and y- direction can 

be made with the marked x- and y- screws
