Fujinon XF 56mm F1.2 and Helios 58mm F2.0 are my 2 main prime lenses for portrait photography (sometimes I use another manual focus lens, the Pentacon 135mm F2.8), when used with a Fujifilm X mirrorless camera. I know many of the Fujifilm users do not have the 56mm prime lens for portraits, but instead, some of them use old legacy manual focus lenses as a cheap and accessible alternative.
