Little lad, one flogging camera? (14)
I believe the answer is:
whippersnapper
'little lad' is the definition.
(whippersnapper can mean a young person)
'one flogging camera?' is the wordplay.
'one flogging' becomes 'whipper' (someone flogging or whipping people).
'camera?' becomes 'snapper' (something which snaps photographs).
'whipper'+'snapper'='WHIPPERSNAPPER'
(Other definitions for whippersnapper that I've seen before include "cheeky upstart" , "Scallywag" , "Pipsqueak" , "Nonentity" , "Cheeky kid" .)
