Best wide angle lens for the fujifilm x pro1?
For the X-Pro1, my pick is the Fujifilm XF 16mm f/1.4 R WR. It frames like 24mm on full frame, which is a proper wide view for landscapes, streets and interiors, and f/1.4 is fast enough for dim light.
If you want one lens that covers more ground, the Fujifilm XF 8-16mm f/2.8 R LM WR goes from 12mm to 24mm full-frame equivalent, with a constant f/2.8 across the zoom.
For something smaller and cheaper, the Fujifilm XF 14mm f/2.8 R gives a 21mm equivalent view. It is a little less bright but a good everyday wide.
The X-Pro1 has no stabilisation in the body, so keep an eye on shutter speeds in dim light. The full range of wide options is on the Fujifilm X-Pro1 page.
