I am searching for a focusing light with a narrow beam and integrated flash sensor,
I want to use the light for mounting on top of the camera, help the camera to focus in dark water with poor visability.
For that it would be good if the light has as a spot spot 500-1500 lumen. Quick Change to wide and red would be perfect, but not the msot important.
The Problem is, that when I use higher Iso and a wide open aperture, then the light of a normal torch is visible on the Photos.
For that it would be great if the light automatically turns off when I take a picture.
Does somebody know such a light or give me a tip?
Thank
Armin
