Samyang AF 24mm f/1.8 FE vs Sony E PZ 10-20mm f/4 G
The bottom line
These cover different focal lengths — the Samyang AF 24mm f/1.8 FE is 24mm, the Sony E PZ 10-20mm f/4 G is 10-20mm — so they're not really substitutes. Pick by the field of view you actually need: the Samyang AF 24mm f/1.8 FE for standard, the Sony E PZ 10-20mm f/4 G for wide-angle.
Choose the Samyang AF 24mm f/1.8 FE if…
- ✓You want more light and background blur — f/1.8 is faster than f/4, better for low light and subject separation.
- ✓You prefer a fast, compact single focal length — a 24mm prime over a zoom.
Choose the Sony E PZ 10-20mm f/4 G if…
- ✓You shoot wide — it starts at 10mm vs 24mm for landscapes, interiors and architecture.
- ✓You want one-lens flexibility — a 10-20mm zoom covers what the fixed 24mm can't reframe.
- ✓You value portability — at 143g (5.0 oz) it's lighter than the 213g (7.5 oz) alternative for travel and all-day carry.
- ✓You work outdoors — it's weather-sealed against dust and moisture; the other isn't.
