What filter size does the 7artisans 10mm f 3 5 take?

I'm afraid the 7Artisans 10mm f/3.5 page doesn't list a filter size, so I won't guess one. Filter threads vary between lenses, so check the lens body or the maker's own listing before you buy.

The page does cover what the lens is for. It's a manual-focus prime that frames wide on APS-C, roughly like 15mm on full frame, and it fits Sony E, Fujifilm X, Nikon Z and Micro Four Thirds mounts.

If you're thinking about filters for landscapes, a circular polariser and ND filters are the two I'd start with. The landscape kit list explains what each one does.
