At the X-E2 which is already quite a Klopper. But also a nice lens, which I now prefer insets, as the combination of Canon 6D with the Sigma 85mm f 1.4. But when I actually even the Fujinon F1.4 XF23mm use but I am looking forward very excited about the available there, simple switching to manual focus and the retro style of the X cameras very reasonable depth of field scale. The 56mm lens would have the very good standing to face.
The performance of the autofocus is, in my very personal opinion - at least in connection with the X-E2 - very improved.
Annoying natural that Fuji film 2 weeks after I bought the lens, a successor announced. That's when you spend before 1000 euros, quite frustrating. I would like to back up waiting for the APO version, if I had known it.
