They all performed as I expected. All these shots were taken at f5.6 and 1/250th sec. with 2 sec self timer. All exhibited CA's even stopped down, and wide open lacked contrast and sharpness, but soon improved. On the X-T1, the Rokkor would be my favourite for its light weight and overall handling, though I prefer the Fujinon and Pentax K colours slightly. For what it goes for the Tokina is certainly no slouch and the bargain of the bunch. There appears to be a slight variation in focal lengths between the lenses.
