What is the fujifilm xf 16 55mm f 2 8 r lm wr good for?
The XF 16-55mm f/2.8 R LM WR is my pick for a serious standard zoom on Fujifilm APS-C bodies. It frames like 24-82mm on full frame, which covers wide scenes, street, and portraits without changing lenses. The constant f/2.8 is the main draw. On APS-C it gives about the depth of field of f/4.2, and it helps in dim light.
It's big and heavy, and it isn't stabilised, so it suits people who shoot in decent light or are happy to use faster shutter speeds. For landscapes, the landscape guide notes that f/4 zooms are lighter and often enough. If you want one camera and one zoom for trips, the travel picks show where a zoom like this fits.
