Let me rephrase the question then.
I know that a 4x5 filter (4x5.65 really but that's the shorthand) is wide enough for the actual physical diameter of the lens, but not sure about the height. Of course, the image is 16x9 so the filter doesn't have to be as tall as it is wide. But is it tall enough that the entire field of view of the lenses will go through the filter and I won't see the edges.
We actually have Schneider 4x4 filters but that is just shy of 114mm and I'm not sure if they are wide enough. Because even though the physical housing of the lens is 114mm, I'm not sure if the filter needs to be that wide as well to cover the entire field of view of the lenses.
I'm less worried about the physical size than the field of view. I was wondering if anyone else has shot with these lenses and what size filters they used.
Is that more clear?
