Coming in at 85mm full frame equivalence, the Fujinon XF56MM F1.2R is a prime (poor pun intended) example of Fujifilm’s focus on APS-C done right. At time of writing, no other manufacturer has a fast prime that provides this classic portrait focal length for APS-C bodies.
The XF56MM was one of the first few lenses that I bought when I switched to the Fujifilm X system, it still amazes me even after two years.
