Sigma EF-610 DG Super
In dedicated wireless mode, it lets the photographer select one of four channels. This is to minimise the risk of interference from other photographer's equipment. No other flash from the other photographers present will be able to trigger yours (apart from another with a compatible master unit set to the same channel). This is very handy if you have to work at social gatherings or weddings where a lot of people fire their compact cameras with flash.
In dedicated wireless mode, the number of groups you can control depends on what flash system is used:
- Canon: The master can control up to three groups. You can set the power ratio from 1:1 to 1:8 with the first two groups, while the third group is controlled by means of setting exposure compensation.
- Nikon: The master can control up to three groups. You can set the flash mode and output level on each group individually.
- Sigma: The master can only control a single group.

Sigma is a family owned manufacturer of photographic equipment founded in 1961 in Japan. The company's main business is to manufacture third party lenses. However they also produce third party flash units and, since 2002, their own line of DSLR and compact cameras. Sigma's digital cameras use a special sensor, developed by Foveon, that records full color information for every pixel. In late 2008 Sigma acquired Foveon.
