I agree with Lakelao. The 28mm (18mm on Fujifilm) perspective lens is a standard lens. Fuji needs to up date their 18mm F2 lens. Strangely there are no independent lens manufacturers that make this particular focal length for Fujifilm cameras. Currently I use the wide extender on my X100s and X100F for this perspective. The 28mm focal length lens for my 35mm film cameras was my main lens that I used from the early 1980's up until the 2010 when I switched full time to digital photography (from Canon5D2 to the Fujifilm system). The 24mm (16mm on Fujifilm) is too wide for my needs.
