Is the 7artisans af 18mm f 2 worth it?

Yes, if you shoot Sony E and have an APS-C body. The 7Artisans AF 18mm f/2 is built for APS-C, where it frames like a 27mm on full frame, and f/2 gives about the depth of field of f/3 there. It autofocuses, but it isn't stabilised, so you'll want decent light or a steady hand. It's a good fit on APS-C bodies such as the Sony a6400.

On a full-frame Sony E body it still works, but only in APS-C crop mode, which means fewer megapixels. If you're going full frame, I'd look elsewhere. For a broader view of the trade-off, see Is full frame worth it?.
