STEP 1: IRIS SUB-ASSEMBLY 

 

THE BELOW PROCEDURE APPLIES FOR ALL OPTIMO PRIME SERIES 

 

0 - Put the iris ring at the maximum opened T-stop position. 

1 - Mount the iris sub-assembly onto the internal part of the IOP element spanner 66067121AA. First, rotate the iris-subassembly anti-clockwise 

so it falls in the correct thread position. 

2 - Tighten the iris sub-assembly up to the end-stop. Do not apply more torque after you reached the end-stop. 

3 - Align the pin positioning hole of the iris sub-assembly with the internal iris positioning pin. Align the iris pin with the internal iris hole. 

4 - Put the iris-sub-assembly back in the lens by sliding straightly the internal part of the IOP element spanner. 

5 - Untighten and pull out the internal part of the IOP element spanner. 

6 - Keeping the lens vertically, check that the iris is functioning correctly by rotating the iris gear. The iris blades should close and open correctly 

and the iris sub-assembly should not move.
