Common questions
Which is better in low light, the Fujinon XF90mmF2 R LM WR or the Samyang AF 75mm F1.8 X?
The Samyang AF 75mm F1.8 X. At f/1.8 against f/2 it gathers 0.3 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.
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.
