Fujifilm XF 18-135mm f/3.5-5.6 R OIS WR vs Viltrox AF 75mm f/1.2 Pro XF
The bottom line
The Fujifilm XF 18-135mm f/3.5-5.6 R OIS WR is a zoom (18-135mm) 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/3.5) and lighter to carry. Choose flexibility or a fast single focal length.
