Sigma EF-610 DG Super and EF-610 DG ST Flashes

At Photokina 2010 this week, Sigma announced a pair of new hotshoe flashes, the EF-610 DG Super and EF-610 DG ST.

Both new flashes feature a Guide Number of 61, manual flash mode and a TTL auto flash exposure with all popular DLSR systems.

The EF-610 DG ST gives you manual power control down to 1/16 power, while the EF-610 DG Super covers an 8-stop range that (assuming my finger counting is correct) gets you down to 1/128 power in manual mode.  Additionally, the EF-610 DG Super features a modeling flash function, multi-pulse flash, TTL wireless flash, high speed sync and rear curtain sync.

For those reading between the lines, the EF-610 DG Super competes with the likes of the Canon 580EX II and Nikon SB-900, while the EF-610 DG ST matches up more with the Canon 430EX II and Nikon SB-600.

No word yet on price or availability for this new pair of flashes, but considering where they fit in the market, you can probably expect them to be priced a little below the first-party products noted above.

More details in the press releases below.

Sigma EF-610 DG Super Press Release

The Sigma Corporation is pleased to announce the launch of the new ELECTRONIC FLASH EF-610 DG SUPER.

The EF-610 DG SUPER features a powerful Guide Number of 61 and is designed to work with the latest TTL auto exposure systems of all popular digital and film SLR cameras. The autozoom function automatically sets the optimum illumination angle in accordance with the lens’ focal length in a range from 24mm to 105mm. When the built-in Wide Panel is used, the flash can cover an angle of 17mm. For bounce flash, the flashgun head can be tilted up by 90 degrees, to the left by 180 degrees, or to the right by 90 degrees. It can also be tilted down by 7 degrees allowing ease of use for close-up photography. Among the advanced features of this flash is a modeling flash function, multi-pulse flash, TTL wireless flash, FP (high speed) flash, rear-curtain Synchro flash and manual flash mode, which allows the photographer to set the flash power level by up to eight stops. The Auto Power-Off function automatically shuts off the LCD panel to help save battery power. When the flashgun is fully charged, a confirmation ‘ready’ light will be emitted.

This product is showcased at Photokina 2010 in Koln, Germany.
