This compact flash brings light into the darkness. The guide number of 40 gives you sufficient possibilities to highlight someone perfectly, also over a distance of several meters. But with flash alone, it does not stop. The i40 has an adjustable LED light that you can use during filming. The i40 zooms automatically with your lens over a distance of 24 to 105 mm. Make use of the TTL light measurement and you hardly have to think about anything anymore.
