A new micro-iris features 55µm thick transparent chemical rings of electrochromic polymer PEDOT (poly 3,4-ethylenedioxythiophene) which turn opaque when 1.5V is applied. The obvious application is in front of CCD cameras in phones but it has other applications.

But if you are using this to adjust the f-stop I would take a 15 second delay to set everything up and then snap quickly. It's not going to change between shots.
