Related Questions and Answers

Q: 1. Would I be able to put a clip on mattbox on this lens to use a polarizer or would that vignette?

A: The diameter of the front of the IRIX 11mm T4.3 Cine Lens (Canon EF, Feet) (B&H# IRC11EFI) -- not to be confused with the filter size -- is 95mm which is a very common size to which to attach a matte box. Yes, it would be possible to do so. Given the ultra wide nature of the field of view, however, there will of course be at least some amount of vignetting regardless of the size of the filter, but that is unavoidable.

Q: 2. Is the lens mount user-swappable?

A: This lens is not user-swappable. I recommend going to Duclos Lenses for professional mount conversion and calibration. They offer the IRIX lenses in ARRI PL, Canon EF/RF, L-Mount, Micro 4/3, Nikon Z, and Sony E mounts.
