I am looking to pick up a Graduated white water glass filter in 4x4 0.6 density.
It appears the Tiffen Digital HD is very scratch resistant and a strong reference but it is very hard to get in Europe without spending at least 50% more than in the US.
I know Schneider makes something equivalent too.
What about Formatt glass grads? It appears a lot cheaper.
How do all of these compare in terms of scratch resistance, neutral grays, glass quality (white water?), IR and optical perfection?
