Fujifilm XC 15-45mm f/3.5-5.6 OIS PZ vs Sigma 30mm f/1.4 DC DN Contemporary (Fuji X)
The bottom line
The Fujifilm XC 15-45mm f/3.5-5.6 OIS PZ is a zoom (15-45mm) and the Sigma 30mm f/1.4 DC DN Contemporary (Fuji X) is a 30mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/1.4 vs f/3.5) and lighter to carry. Choose flexibility or a fast single focal length.
