Inclines to overlook a camera feature (4)
I believe the answer is:
lens
'camera feature' is the definition.
(I've seen this in another clue)
'inclines to overlook a' is the wordplay.
'inclines' becomes 'leans' ('lean' can be a synonym of 'incline').
'to overlook' is a deletion indicator.
'leans' with 'a' taken out is 'LENS'.
(Other definitions for lens that I've seen before include "Focussing device" , "Part of photographer's equipment" , "optical equipment" , "Aid for viewing" , "Photographer's accessory" .)
