This lens is from a larger optical system.  The control motors are Faulhaber 2342S012CR and these are geared for higher force.  The Iris is controlled by a smaller 15mm motor also geared.  There is a rotary solenoid that operates a shutter mechanism. Feedback for all devices is monitored by Resistance encoders in 3 places.  We were only able to test the motors, and the lenses were inspected for damage. Rodenstock 1:1.4-1.6.
