View finders? (4)
I believe the answer is:
eyes
'view finders?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eyes that I've seen before include "Organs of vision" , "Globular organs" , "(Paradoxical?) film with Cruise and Kidman" , "Marks on potatoes" , "Visual organs" .)
