I own the Samyang 8mm fisheye and use it from time to time with my x-e2 and x-t1. Because the effect that it creates isn't something that is continuously called for, it doesn't come out of the bag all that often, but it is useful. So far the X-lineup of lenses has filled just about every focal range I've needed, but fisheye is the one exception. The only thing that I miss after selling my collection of Canon gear is having a fisheye that works with the camera electronics. I wonder if the demand is high enough for this unusual tool that Fuji will provide us with such glass fitted with their superior optics and continually more snappy autofocus? Apparently the demand was high enough for Canon to supplement the 15mm fisheye with an 8-15 fisheye zoom, and even produce it to L-series standards. I haven't seen this discussed elsewhere so I wonder if I'm the only person who would love to see Fuji follow suit...
