See first fellow flog photographer's equipment (5)
I believe the answer is:
flash
'photographer's equipment' is the definition.
'flash' can be an answer for 'equipment' (flash is a kind of equipment). I'm not sure about the 'photographer's' bit.
'see first fellow flog' is the wordplay.
'see first fellow' becomes 'f' (lst letter of 'fellow').
'flog' becomes 'lash' (synonyms).
'f'+'lash'='FLASH'
Can you help me to learn more?
(Other definitions for flash that I've seen before include "Short gleam of light" , "Momentary brightness" , "Gaudy" , "Conspicuously display" , "Instant" .)
