Sigma has a new hotshoe flash, the Electronic Flash EF-630. Designed for DSLR cameras, it includes all the features you might expect from a flagship flash including TTL exposure control, high-speed sync, a tilting, swivelling head, auto-zoom (24–200mm) and (optical) wireless control. It has a guide number (GN) of 63.

“Lighting is one of the most important factors when it comes to creating a beautiful image, and can be the difference between capturing the perfect moment and missing it entirely,” said Mark Amir-Hamzeh, president of Sigma Corporation of America, in a press release. “The EF-630 has all the features advanced photographers look for in a flash and is the perfect companion to the DSLR.”

Firmware updates are supported, but rather unusually you can’t just do it through a micro-USB port in the flash itself. Instead Sigma reckons you’ll buy its Flash USB Dock, sold separately.

The EF-630 should probably be available for Nikon, Canon and Sigma flash systems. No pricing has been announced yet. Pre-release pages are live at Adorama:
