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 functions are also available for advanced flash photography.

First ring flash and I am happy so far with the pictures I have taken. Some nice portraits and bug shots. Very happy with the price and the quick B&H shipping.
The user manual is not the best and a complete set of adaptor rings would be nice

Have not used this as of yet. Just dragging my feet. I'll get around to it.
