Laowa 15mm f/2 Zero-D vs Sony E PZ 10-20mm f/4 G
The bottom line
The Sony E PZ 10-20mm f/4 G is a zoom (10-20mm) and the Laowa 15mm f/2 Zero-D is a 15mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/2 vs f/4) and lighter to carry. Choose flexibility or a fast single focal length.
Choose the Laowa 15mm f/2 Zero-D if…
- ✓You want more light and background blur — f/2 is faster than f/4, better for low light and subject separation.
- ✓You prefer a fast, compact single focal length — a 15mm prime over a zoom.
Choose the Sony E PZ 10-20mm f/4 G if…
- ✓You need more reach — it goes to 20mm vs 15mm for distant subjects, wildlife and sport.
- ✓You shoot wide — it starts at 10mm vs 15mm for landscapes, interiors and architecture.
- ✓You want one-lens flexibility — a 10-20mm zoom covers what the fixed 15mm can't reframe.
- ✓You value portability — at 143g (5.0 oz) it's lighter than the 395g (13.9 oz) alternative for travel and all-day carry.
