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 Samyang AF 12mm F2 X if
- low light is the priority. At f/2 it lets in 1 stops more than f/2.8 — faster shutter speeds indoors and softer backgrounds.
- you want more in the frame. It starts at 18 mm equivalent, against 21 mm on the other lens — interiors, landscapes and groups at close range.
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 better in low light, the Fujinon XF14mmF2.8 R or the Samyang AF 12mm F2 X?
The Samyang AF 12mm F2 X. At f/2 against f/2.8 it gathers 1 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.
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.
