Fujifilm GF 20-35mm F4 R WR vs Fujifilm GF 23mm F4 R LM WR
Fujifilm GFX
Both are weather-resistant f/4 wide-angle lenses for the Fujifilm GFX medium format system. The GF 23mm f/4 R LM WR (2017) is a prime with a linear motor, equal to about 18 mm in full frame terms, and weighs 845 g. The GF 20-35mm f/4 R WR (September 2022) is a zoom with an internal zoom design whose length does not change. At 725 g it is even lighter and its 20 to 35 mm also covers the 23 mm focal length. Both take 82 mm filters.
On paper the zoom is the more flexible choice; the prime is the option for those who deliberately work with a single focal length.
Which one suits whom?
- GF 23mm: You like working with one fixed focal length and want linear-motor focusing.
- GF 20-35mm: You want to stay flexible between 20 and 35 mm while saving weight.
