Hi everyone,

I'm using my F3 with some nice Leitz lenses, but hitting a problem, trying to get the follow focus working with the light trap/matte box.

I'm using a neoprene doughnut. The excess material beneath the lens keeps the follow focus from getting where it needs to be.

Apart from cutting the material across the bottom, is there a solution to this? What are other folks using as a light trap with their SLR lenses?

thanks,

Tom
