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 XF18-55mmF2.8-4 R LM OIS if
- your subject is far away. It magnifies 1.66× more, and walking closer is not always an option.
- you want more in the frame. It starts at 27 mm equivalent, against 50 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 XF33mmF1.4 R LM WR if
- low light is the priority. At f/1.4 it lets in 2 stops more than f/2.8–4 — faster shutter speeds indoors and softer backgrounds.
- 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.
