Fujifilm xf 18 120mm f 4 lm pz wr vs sigma 50 120mm f 2 8 dc os contemporary?

Both are APS-C zooms that fit Fujifilm X bodies, but they answer different needs.

The Fujifilm XF 18-120mm f/4 LM PZ WR is the all-round one. It runs from wide to telephoto, so it's a sensible single lens for travel and everyday shooting. It isn't stabilised, and f/4 is slower in dim light.

The Sigma 50-120mm f/2.8 DC OS Contemporary is the one for people and low light. The constant f/2.8 gives more subject separation and better light gathering, and it has stabilisation. It has no wide end, though, and it also mounts on Sony E and Canon RF bodies.

If you want a single lens for travel, go Fujifilm. If you mostly shoot people or indoor scenes, go Sigma. For how wide apertures shape background blur, see Portraits: aperture and background blur.
