14 DAY TRIAL // Sigma has just announced the revamping of its flashgun lineup with two new models, the EF-530 DG Super and the EF-530 DG ST, the first being the top of the line.
Although they basically have the same specifications, the Super version does have some of the "pro" features; these include 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.
Aside from all the above, the two models are identical, both of them having a Guide Number (GN) of 53, autozoom function that automatically sets the optimum illumination angle in accordance with the lens' focal length in a range from 24mm to 105mm and a built-in wide panel for 17mm.
As for the flashgun head, it 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.
The two flashes are available for Sigma, Nikon, Canon, Sony and Pentax cameras and all of them support TTL technology.
The Sigma EF-530 DG SUPER has an MSRP of around ?219.99 in the UK, while the EF-530 DG ST will be available for around ?120.
