Great stuff jj. I am very pleasantly surprised at how the 100-400 feels on the X-T10, let alone the X-T1. The throw even at 400mm is fairly minimal so it just feels like a long prime rather than a super extended zoom.
Tripod foot is tiny though, used to occasionally hold big heavy teles by the foot but that's not an option with this one.
Would like to see a longer minimum distance on the limiter as well, 5m is nothing when you're using such a long zoom. At the zoo it wasn't long enough to get past the fences, 8m would be perfect (I'm spoiled there as my old Sony could be configured in camera)
