Product Description

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 flash tube 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.

Features

  • Fully dedicated with E-TTL II Canon EOS cameras (A-TTL not supported)
  • 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
