Sigma is set to launch a macro flash unit designed for Pentax and Sony digital SLRs.

Designed for both 35mm film and digital SLRs the EM-140 DG Macro Flash contains dual flash tubes designed to fire simultaneously or separately.

A Sigma spokesman said: ?Using only one flashtube creates shadow, 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 picture.?

Carrying a guide number of 14 the EM-140 DG can also serve as master for a wireless flash function, with the EF-530DG SUPER acting as the slave unit.

A price had not yet been set when we went to press.
