Is the samyang af 85mm f 1 8 p fe good in low light?

Yes, for low light it's a good match. At f/1.8 it gathers far more light than any kit zoom, and the guide makes the same point about primes. It's also light, at about 270 grams, so you'll actually carry it.

Two things to keep in mind. It isn't stabilised, so in dim rooms you'll want a shutter speed that's fast enough to freeze hand shake. And the lens is made for full frame, where full frame is worth it for low light and portraits. For bodies, I'd start with the Sony a7 III or the Sony a7 IV, both full frame and both on the list this lens fits.
