I have just bought another Sigma 30mm 1.4 for a holiday in Croatia and I was out shooting at the weekend and I found that I was hitting the max shutter speed. Can anyone recommend what strength ND (1 stop 2 stop, or more?) and a brand? I don't want to spend too much as I will be selling on the lens after the trip, but I bought the 30mm to use at F1.4 so feel I need this filter.
Many thanks
