Sony E 11mm f/1.8 vs Sony E PZ 18-105mm f/4 G OSS
The bottom line
These cover different focal lengths — the Sony E 11mm f/1.8 is 11mm, the Sony E PZ 18-105mm f/4 G OSS is 18-105mm — so they're not really substitutes. Pick by the field of view you actually need: the Sony E 11mm f/1.8 for wide-angle, the Sony E PZ 18-105mm f/4 G OSS for standard zoom.
Choose the Sony E 11mm f/1.8 if…
- ✓You want more light and background blur — f/1.8 is faster than f/4, better for low light and subject separation.
- ✓You shoot wide — it starts at 11mm vs 18mm for landscapes, interiors and architecture.
- ✓You prefer a fast, compact single focal length — an 11mm prime over a zoom.
- ✓You value portability — at 181g (6.4 oz) it's lighter than the 427g (15.1 oz) alternative for travel and all-day carry.
Choose the Sony E PZ 18-105mm f/4 G OSS if…
- ✓You need more reach — it goes to 105mm vs 11mm for distant subjects, wildlife and sport.
- ✓You want one-lens flexibility — a 18-105mm zoom covers what the fixed 11mm can't reframe.
- ✓You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
- ✓You use filters or shoot video — internal zoom keeps length and balance constant.
