Definitely best to stay away from here!
When I was knee-deep in the Fuji-X-E1 system, this was an excellent lens for me. IIRC though, there is no focus limiter (would someone correct me here if this is wrong please); as a result, its slowness in AF can result from moving all that distance from near to far. Once it has, though, in a portrait situation, for example, it focusses adequately quickly. Razor sharp at ƒ2.4, as others have noted.
