Is the fujifilm gf 30mm f 5 6 t s weather sealed?
The Fujifilm GF 30mm f/5.6 T/S page doesn't say whether it's weather sealed. Its spec list covers the maker, focal length, aperture, sensor format, mount, stabilisation and autofocus, but not sealing, so I won't guess.
If you're planning landscape work in wind, spray or drizzle, weather sealing matters. I'd treat it as a must-check before buying. The Landscape guide explains why a sealed body and lens are worth having at dawn. You can read the full Fujifilm GF 30mm f/5.6 T/S page for everything it does list, or check the manufacturer's listing before you buy.
