Panasonic LUMIX G 20mm f/1.7 ASPH. vs Panasonic LUMIX G VARIO 12-32mm F3.5-5.6
The bottom line
The Panasonic LUMIX G VARIO 12-32mm F3.5-5.6 is a zoom (12-32mm) and the Panasonic LUMIX G 20mm f/1.7 ASPH. is a 20mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/1.7 vs f/3.5) and lighter to carry. Choose flexibility or a fast single focal length.
