Hi all, I am new here. I have used the XT-1 before but not the XT-2. Currently I am a Canon user and focusses a lot on birds in action. I really would like to buy the XT-2 and the 100-400 combo but I am not sure how it will stack up against the Canon 7d2 and the Canon 100-400. I am not really happy with the Canon combo as the hit rate is only about 60% or less. Does anyone here shoot birds in action with the XT-2 and 100-400? Can anyone enlighten me more on this? Thanks.
