While I may have lost 2mm, I gained compatibility with my current filters as the Fuji takes 58mm filters vs the Rokinon's 67mm filter thread. The reviews for this lens support my initial experience in that the 14mm is very sharp with minimal distortion.
This weekend I took my new/used lens for a spin around my neighborhood with walks around Stillhouse Cove, Salters Grove, and Gaspee Point.
In just the three days I have used it, the 14mm may very well rival to the 35mm as my favorite lens. I already anticipate these two lenses, along with the X-T1, will be the core of my travel kit.
