Sigma EM-140 DG TTL Macro Ringlight Flash (Guide No. 46'/14 m) for Sony Alpha & Minolta Maxxum

The Sigma EM-140 DG Ring Flash is 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 the EF-500 DG Super as a slave unit for creating fine shadow details. High Speed Synchro and exposure compensation functions are also available for advanced flash photography.
