Is the fujifilm gf 35 70mm f 4 5 5 6 wr worth it?
It's worth it if you already shoot with a GFX body, and it's the only real option for that system. The Fujifilm GF 35-70mm f/4.5-5.6 WR is a Medium format zoom that frames roughly like a 28-55mm on full frame. It isn't stabilised, and it gets darker as you zoom in, so it's a daylight and general-purpose lens rather than a low-light one. Your camera's sensor will do more for you than a faster lens would in most hobby shooting, as Sensor sizes explains.
It only fits GFX bodies, so check your mount first. It pairs well with the Fujifilm GFX 50S II or the Fujifilm GFX100 II. If you need faster light-gathering, look at the Lenses guide before you buy.
