Hitech 1.2ND filter(4 stop)

[tomh1982]

Just wondering if anyone has any experience with one of these?
I want to do some long exposures but don't think I want anything as mighty as a 10 stopper.

Thing I'm most concerned about with the hitech is if it gives a strong colour cast? (I know the hitech 10stop does)

The colour cast of the Hitech Pro Stop can easily be fixed in post.

Cheers.
