EF 610 SIGMA Flash

This EF610 DG ST SIGMA SIGMA flash is a powerful (guide number 61) flash shoe mount designed for use with SIGMA cameras. Auto flash TTL exposure control is available for all compatible cameras. An auto-zoom function automatically adjusts the optimal angle of illumination according to the focal length used (from 24 mm to 105 mm), or the built-in width panel, 17 mm.

The flash head can be tilted up and right 90 degrees, left 180 degrees for greater flexibility in using bounce flash or by 7 degrees for close-up photography. There's also a manual flash mode, so it's possible to adjust the flash power to full or 1/16 power. A confirmation light keeps you informed when the flash is fully recycled, and there's an auto-off feature to help save battery power.
