I wonder wich nd strengths I'm going to need to shoot with the bmmcc at ISO 800 in bright daylight. Im speaking about 4x4 filters for a mattebox because my lenses have no filter threads. So what would be the most versatile option without the need to spend too much money on it? I also wouln't like to stack nd's because i might put an ir filter in front and i have only two trays to work with.
Thanks in advance.
