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

These two are both APS-C zooms, but they answer different questions. The Sigma 50-120mm f/2.8 DC OS Contemporary is the brighter, stabilised choice. It stays at f/2.8 across its range, roughly 75-180mm equivalent on Sony E or Fujifilm X, so it suits portraits and tighter subjects with plenty of background blur.

The Fujifilm XF 18-120mm f/4 LM PZ WR goes much wider, about 27-180mm full-frame equivalent, but it's slower at f/4 and not stabilised. If you shoot Fujifilm X and want one lens for everything, especially travel, this is the one I'd pick. For people and low light, the Sigma is the better tool.
