The Sigma EM-140 DG Macro Ring Flash is ideal for photographing subjects in fine detail and is extremely effective for scientific and medical applications. Dual flash tubes can fire simultaneously or separately. Using only one flash tube creates modelling, which can give a three-dimensional feeling to the subject.

A wireless flash function is also available, where the EM-140 DG is used as master. 55mm and 62mm adapter rings are included with the flash. 52mm, 58mm, 67mm, 72mm and 77mm adapters are sold separately.
