I actually sold it this year after I ditched most of my Pentax gear. Why?
I bought the XF27mmF2.8 lens which on the APS-C sensor of the Fuji provides the FF equivalent FOV of approximately 41.04mm. The wider aperture and smaller and lighter Fuji lens made the Pentax lens superfluous.
I replaced the heavy Pentax gear with the lighter Minolta X-700 and XD-11 and bought two lenses, the MD Rokkor-X 45mm f/2 and 50mm f/1.7.
