Cameras that take both
Both lenses fit every interchangeable-lens X Series body — 34 in our list. Fixed-lens models such as the X100 series cannot take them.
Which one to choose
Choose the Fujinon XF10-24mmF4 R OIS WR if
- your subject is far away. It magnifies 1.33× more, and walking closer is not always an option.
- you want more in the frame. It starts at 15 mm equivalent, against 27 mm on the other lens — interiors, landscapes and groups at close range.
- your camera body is not stabilised. Of these two, only this lens has optical stabilisation.
Choose the Fujinon XF18mmF1.4 R LM WR if
- low light is the priority. At f/1.4 it lets in 3 stops more than f/4 — faster shutter speeds indoors and softer backgrounds.
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
Which is lighter, the Fujinon XF10-24mmF4 R OIS WR or the Fujinon XF18mmF1.4 R LM WR?
The Fujinon XF18mmF1.4 R LM WR, by 15 g — about 4% less.
Which is better in low light, the Fujinon XF10-24mmF4 R OIS WR or the Fujinon XF18mmF1.4 R LM WR?
The Fujinon XF18mmF1.4 R LM WR. At f/1.4 against f/4 it gathers 3 stops more light, which matters without flash and for background blur. Stabilisation can offset some of that for still subjects, but not for moving ones.
Do the Fujinon XF10-24mmF4 R OIS WR and Fujinon XF18mmF1.4 R LM WR use the same filters?
No. The Fujinon XF10-24mmF4 R OIS WR takes ⌀72 mm and the Fujinon XF18mmF1.4 R LM WR ⌀62 mm. A step-up ring lets the smaller lens use the larger filters.
Will both lenses fit my camera?
Both use the Fujifilm X mount, so they fit any X Series camera with interchangeable lenses. They do not fit fixed-lens models such as the X100 series or GFX bodies.
