What filter size does the 7artisans 4mm f 2 8 fisheye take?

I don't have the filter thread size for the 7Artisans 4mm f/2.8 Fisheye on this site, so I won't guess. The 7Artisans 4mm f/2.8 Fisheye page lists its mounts, aperture, and what it frames like, but not filter size. The manufacturer's own spec sheet or the box will have it, and that's the safest place to check before you buy a filter.

If you're thinking about filters for landscape work, the landscape kit section covers the circular polariser and ND filters I'd start with.
