Used on a canon 550d. The light is a bit blue but easily compensatable in post production. Good distribution, uniformly distributed without hot spot. The light turns on to assist in the development. There are 3 levels of power. It's a little too powerful in some rare cases. The scope is however limited. Somewhat effective for macro but do not expect to use it as a standard flash. Usable on the accessory shoe on the lens or deported. You can also manually trigger was holding the hand. Works with a trigger cell if needed. 4 stars because it is found less at other sellers on amazon.
