Fujifilm XF 18-120mm f/4 LM PZ WR vs Viltrox AF 75mm f/1.2 Pro XF
The bottom line
The Fujifilm XF 18-120mm f/4 LM PZ WR is a zoom (18-120mm) and the Viltrox AF 75mm f/1.2 Pro XF is a 75mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/1.2 vs f/4) and lighter to carry. Choose flexibility or a fast single focal length.
