Sharp intelligence of copper (2,5)
I believe the answer is:
in focus
'sharp' is the definition.
(I've seen this in another clue)
'intelligence of copper' is the wordplay.
I cannot really see how this works, but
'intelligence' could be 'info' (I've seen this before) and 'info' is found within the answer.
'copper' could be 'cu' (chemical symbol) and 'cu' is found within the answer.
A single letter 's' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for in focus that I've seen before include "Clear" , "Clearly defined" , "Not blurred" .)
