Sony FE 100mm f/2.8 Macro GM OSS vs Sony FE 24-105mm f/4 G OSS
The bottom line
The Sony FE 24-105mm f/4 G OSS is a zoom (24-105mm) and the Sony FE 100mm f/2.8 Macro GM OSS is a 100mm prime. The zoom gives you framing flexibility from one lens; the prime trades that for a fixed focal length that's usually brighter (f/2.8 vs f/4) and lighter to carry. Choose flexibility or a fast single focal length.

- ✓You shoot close-ups — 1.4x magnification gets you true macro the other can't.
- ✓You prefer a fast, compact single focal length — a 100mm prime over a zoom.
Choose the Sony FE 24-105mm f/4 G OSS if…
- ✓You shoot wide — it starts at 24mm vs 100mm for landscapes, interiors and architecture.
