Nissin flashguns offer plenty of bang for your buck, and this ring flash continues the trend. An alternative to the macro ringflashes made by major manufacturers, this model allows the light from each of its sides to be controlled independently. It offers a guide number (GN) of 16m at ISO100, and is compatible with Nikon, Canon and Sony TTL metering algorithms, and provides support for wireless shooting by acting as a master to a number of slaves.
Nissin has generoursly thrown in six adapter rings for use with different lenses as standard - allowing you to attach to lenses with 52mm, 58mm, 62mm, 67mm, 72mm, or 77mm front filter threads. Adapter rings are available for purchase separately for 49mm, 55mm, and 82mm threads ($30/£25 each).
