The Yongnuo YN24EX is a macro twin-head TTL flash for Canon, with two independently-adjustable flash heads mounted on a lens ring — ideal for close-up, macro, dental and jewellery photography where you need directional control over the light.
Directional twin-light alternative to a ring flash (e.g. the YN-14EX II) for shaping shadow and depth in close-up work.
