I want to use ND filters with my Hasselblad CF 40mm lens but I am concerned about vignetting. I am looking at 100mm filter holders from Cokin, Lee and Hitech and at circular filters which I will probably have to use with a step-up adapter ring because I have not found any 93mm filters, only 95mm ones.
So, what is your experience?
I would prefer to work with a 100mm filter holder because it will also allow me to use graduated ND filters. Will they cause vignetting? What alternatives are available?
