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.

• Fully dedicated with Sony's ADI flash operation system
• Wireless TTL flash control (4 channels), with Manual Exposure possible
• High Speed Synchro flash
• Stroboscopic effect (power level and frequency customizable)
• Modeling light, also provides AF assist
• Backlight illuminated LCD panel
