Which one to choose
Choose the Fujinon XF16mmF1.4 R WR if
- low light is the priority. At f/1.4 it lets in 1 stops more than f/2 — faster shutter speeds indoors and softer backgrounds.
- you want more in the frame. It starts at 24 mm equivalent, against 27 mm on the other lens — interiors, landscapes and groups at close range.
- the weather is part of the job. Only this one is sealed against dust and moisture.
Choose the Fujinon XF18mmF2 R if
- weight matters to you. It is 259 g lighter, roughly 69% less to carry.
Everything above comes from published specifications. How sharp each lens is, how quickly it focuses and what its pictures look like are not in any spec sheet, so this comparison does not try to judge them.
