OM System M.Zuiko Digital 25mm f/1.8 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 OM System M.Zuiko Digital 25mm f/1.8 is a 25mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/1.8 vs f/3.5) and lighter to carry. Choose flexibility or a fast single focal length.
Choose the OM System M.Zuiko Digital 25mm f/1.8 if…
