Hi, I am looking for a recommendations for 100mmx100mm ND filter (I've got Lee holder). Preferably 9 or 10 stops, but would consider getting a 6 stop as well. Some of them have a strong color cast, like a Big Stopper from Lee, so I am trying to avoid that. I have seen reviews from NiSi, looks good, but was wondering about other choices like Rollei, Haida etc since I have not seen reviews of those.
Any thoughts?
Thanks.
