TheSigma EM-140 DG Ring Flashis ideal for photographing subjects in fine detail - close-up photography - and is extremely effective for scientific and medical applications.
Dual flash tubes can fire simultaneously or separately. Using only one flashtube creates modeling, which can give a three-dimensional feeling to the subject. The Modeling Flash function makes it possible to check for reflections and shadows before actually taking the flash picture.
A wireless flash function is also available, where the EM-140 DG is used as master and theEF-500 DG Superas a slave unit for creating fine shadow details. High Speed Synchro functions are also available for advanced flash photography.
