I've been thinking about buying a ND filter for my 35mm f1.4 lens, but have no idea how many stops it should have.
It will be for ordinary family vacation shots. Nothing fancy.
I want to be able to take pictures at f1.4 in the south of Europe where the sun can get really intense during the summer, and my x-pro 1 has a minimum shutter speed of 1/4000/s, so what would be your guess, how many stops should the ND filter have?
