Panasonic LUMIX G Vario H-FS35100K 100mm
This Panasonic 35-100mm f/4-5.6 lens is widely praised for its incredibly compact size and light weight, making it an ideal travel companion for Micro Four Thirds cameras like the GM5 and GX85. Users consistently report excellent sharpness and image quality for its price point, though many note the slow f/4-5.6 aperture limits low-light performance. The lens pairs perfectly with the 12-32mm kit lens for a versatile, pocketable setup, but some users mention a stiff zoom ring and compatibility quirks with non-Lumix bodies.
Pros
- Extremely compact and lightweight
- Excellent sharpness and image quality
- Great value for the price
- Perfect travel companion
- Pairs well with 12-32mm kit lens
Cons
- Slow aperture limits low-light performance
- Stiff zoom ring
- No optical stabilization on some bodies
- AF can be slow and struggles close-up
- MF ring disabled in AF mode
