I have some work coming up where I will be using a Sony A7RIII to shoot a little movie. And, at 800 ISO, that will require using some heavy ND filters.
Does anyone have a suggestion about what would be a good choice of ND filters to use with this camera? I will need ND .9, 1.5, and 2.1 filters. I am concerned about IR contamination and assume I will need IRND filters when working with ND filters darker than .9.
I am looking for filters that will have a minimum of color shift. And are there filters that are best matched, IR blocking wise, to this camera and sensor?
I believe our lenses take a 72mm screw mount. We would prefer this over using a matte box, if possible or practical.
Thanks!
