BUILD QUALITY: The Sigma unit has been cleverly designed. The buttons are all laid out with decent spacing, so you won’t press the wrong button at the wrong time. The LCD screen is bright and clear, although the battery compartment slider could be a potential weak spot after sustained use. 

FEATURES: With a host of features, it will take you 
quite a while to read through the EF-530’s instruction manual. One interesting feature is the High Speed Sync, which allows you 
to fire the unit at shutter speeds above your camera’s usual 
flash sync speed. The unit can be used as a master or slave 
unit and also offers a wide-angle flash diffuser.

PERFORMANCE: Overall, the exposure results from the 
Sigma EF-530 DG Super were very good. The wide-angle shot showed expected fall-off at 18mm (its coverage only extends to 24mm), it’s not designed but the exposure at the centre was spot-on, as was its performance with bounce flash.

VERDICT: A decent all-rounder. The Sigma maintained a neutral colour temperature in both of our images.
