Panasonic LUMIX S PRO 70-200mm f/4 O.I.S. vs Sigma 135mm f/1.4 DG DN Art (L-mount)
The bottom line
The Panasonic LUMIX S PRO 70-200mm f/4 O.I.S. is a zoom (70-200mm) and the Sigma 135mm f/1.4 DG DN Art (L-mount) is a 135mm 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/4) and lighter to carry. Choose flexibility or a fast single focal length.
