I am shooting some long exposure coastal work and need to use a 10-stop filter. Getting a Lee Big Stopper is impossible, with a lead time of 6-8 months. So I purchased a Format Hitech Pro Stop 10. The reviews of it are as good, and better in some ways, than the Big Stopper.
The Format filter slides in the Lee foundation holder, but the thickness of the foam seal (that borders the filter) is a bit too thick. That causes the filter to bow outward. And that allows light leaks on two of the four sides.
Has anyone ran into this problem? If so, what can I do?
PLEASE email a response directly to me, as well as posting here.
