Sigma Flash
Macro Ring EM-140 DG for Nikon SLR Cameras Description
and Reviews.
Product Description:
From the Manufacturer
The Electronic Flash Macro EM-140 DG is designed to work with both
AF 35mm film and digital SLR cameras of all popular manufacturers.
It is ideal for photographing subjects in fine detail when the
shadowless mode is used and is extremely effective for scientific
and medical applications. Dual flash tubes can fire simultaneously
or separately. Using only one flashtube creates shadow, which can
give a three-dimensional feeling to the subject. The flash
features a guide number of 14 with ISO 100. 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, when 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.
