Sigma EF-500 DG Super Flashgun - Sigma Dedicated

The Sigma EF‑500 DG Super offers a powerful, flexible lighting solution for photographers shooting with Sigma‑dedicated systems. With a guide number of 50 m at ISO 100 (at 105 mm), it gives strong reach even outdoors. The zoom head covers roughly 28‑105 mm, and a built‑in wide panel diffuses the light for wider lenses (≈ 17 mm) without vignetting. The head tilts 90° up, down ≈ 7° for close‑ups, and swivels left/right across wide angles for bounce lighting.
