Is the nikon af s 18 35mm f 3 5 4 5g ed worth it?
Yes, if you want a cheap, small wide zoom for a full-frame Nikon. It covers 18-35mm on full frame, and it's a light way to get wide-angle shots for landscapes, interiors and street work. It fits a long list of Nikon full-frame bodies, including the D750, D850 and D780.
Be realistic about the limits. The maximum aperture drops from f/3.5 to f/4.5 as you zoom, it has no stabilisation, and it won't help much in dim light or with shallow depth of field. If you want more reach for everyday shooting, the Nikon AF-S 24-85mm f/3.5-4.5G ED VR is a common full-frame kit zoom with stabilisation. For more on whether full frame suits you, see Sensor sizes.
