As a stopgap

As a backup for a Studio shooting I bought this ring light. For smaller projects, or as an emergency solution that's enough, really a lot but you should not expect. The light is bright, for macro photography it is sufficient, for a video shoot to be used only conditionally, unless it does not interfere with that you then also always sees the small cone of light.

Really difficult I find the reference. There are several adapter rings, bombproof not sit but the light and loosens repeatedly what annoys especially with moving footage.
