A full-featured ring flash for working in close

For Macro, Medical and Scientific photography you can't go past this Sigma Ring flash for improving your images and helping you capture the more delicate details. Close-up photos are made even more striking and detailed with the addition of such a device, that helps by producing even-lighting across the frame, the Sigma EM-140 Ring Flash for Canon cameras.

AF Assist & LCD Panel - Designed for ease of use

For enhanced usability, the Sigma EM-140 Ring Flash features a modelling light that can be implemented for AF assist, particularly useful for photographing in darker circumstances where your camera may need a bit of help finding autofocus. Settings can be viewed quickly and easily on the backside-illuminated LCD screen, so you can efficiently make any necessary adjustments.

Dual Flash Tubes - Create your signature look

The Sigma EM-140 features dual flash tubes that can be fired simultaneously for an even spread of lighting, or separately for a modelling style, which results in a more dynamic three-dimensional effect on your images. This versatility leaves it in your hands to leave your mark on your photographs and develop your own signature look.

Further functionality - High-speed synchro & Stroboscopic effect

To shoot with your lens wide open for increased depth of field in your close-up images, the Sigma EM-140 is capable of High-speed synchro flash. This enables you to shoot at higher shutter speeds and still achieve accurate exposure, leaving you to explore selective focus and further enhance the power of your macro shots.


For further flexibility, the flash is also capable of stroboscopic effect, with the addition of customisable power level and frequency, and there is also wireless flash functionality, using the EF-500 DG Sigma flash as a master unit.
