Which one to choose
Choose the Fujinon XF50-140mmF2.8 R LM OIS WR if
- low light is the priority. At f/2.8 it lets in 1 stops more than f/4–5.6 — faster shutter speeds indoors and softer backgrounds.
Choose the Fujinon XF70-300mmF4-5.6 R LM OIS WR if
- your subject is far away. It magnifies 2.14× more, and walking closer is not always an option.
- you photograph small things up close. It reaches 0.33× magnification, compared with 0.12×.
- weight matters to you. It is 415 g lighter, roughly 42% 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.
