What is the fujifilm gf 35 70mm f 4 5 5 6 wr good for?
The GF 35-70mm f/4.5-5.6 WR is a standard zoom for Fujifilm's medium format GFX bodies. On those sensors it frames roughly like a 28-55mm does on full frame, which makes it a practical everyday lens for general shooting and landscapes that don't need very wide angles.
Its aperture narrows as you zoom in, so it's happiest in good light. Landscape work usually means stopping down to f/8 to f/11 anyway, so that's no real handicap there. It's autofocus but not stabilised, so keep your shutter speed up when shooting handheld.
For wider landscape options, see the lens section of the Landscape guide. If you're building a kit from scratch, Lenses explains what to add first.
