Dedicated Canon Flash System

The Sigma EF-630 is a dedicated electronic flash built for Canon E-TTL and E-TTL II metering. It mounts on the hot shoe of compatible EOS bodies ranging from the Rebel series to the 1D X Mark II. Photographers gain full TTL automation plus manual control from full power down to 1/128.

Sustained Shooting Behaviour

Wireless TTL triggering lets the unit operate off-camera while maintaining automatic exposure control. High-speed sync fires at shutter speeds faster than 1/250 second for fill flash in bright conditions. Three distribution modes — normal, guide-number priority and flat light — adapt output shape to the scene.

Thermals Noise and Power

The flash head tilts from -7 to 90 degrees and rotates 180 degrees left or right for full 360-degree bounce coverage. Auto-zoom matches the 24-200 mm focal range and a guide number of 63 at 200 mm and ISO 100. An AF assist lamp aids focus in dim light and the unit weighs 1.95 kg.

Questions about this item

How much heat or power does the EF-630 draw when it fires at full 1/1 output all day?

The flash runs on four AA cells and recycles in about 3 seconds at full power; it does not draw mains power and produces no measurable heat during normal use.

What else must I already own for the EF-630 to work on my Canon body?

You need a Canon EOS camera with an E-TTL / E-TTL II hot shoe and four AA batteries; the unit mounts directly without extra cables or triggers.

Will the EF-630 still fire correctly if I keep using my older EF lenses on a newer EOS body?

Yes, the flash meters through the camera's E-TTL II system regardless of lens age, and the auto-zoom covers 24-200 mm to match most EF focal lengths.
