Which one to choose

- weight matters to you. It is 64 g lighter, roughly 36% less to carry.
Choose the Fujinon XF23mmF2 R WR if
- your subject is far away. It magnifies 1.3× more, and walking closer is not always an option.
- the weather is part of the job. Only this one is sealed against dust and moisture.
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.
