Which one to choose
Choose the Fujinon GF23mmF4 R LM WR if
- low light is the priority. At f/4 it lets in 1 stops more than f/5.6 — faster shutter speeds indoors and softer backgrounds.
- you want more in the frame. It starts at 18 mm equivalent, against 24 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.
- weight matters to you. It is 495 g lighter, roughly 37% less to carry.
Choose the Fujinon GF30mmF5.6 T/S if
- your subject is far away. It magnifies 1.33× more, and walking closer is not always an option.
- you photograph small things up close. It reaches 0.21× magnification, compared with 0.09×.
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.
Common questions
