I enjoy the size and weight (or lack of) on my Fujifilm gear, but the AF system and lack of a quality flash system is why the 5D Mark III will remain with me for the foreseable future. I don't think I would have investing in the X-T1 has I not ended up with sever tendonitis on my right hand and elbow. The X100 would have been fine, but I did feel the system was worth investing in as a second system. Looking forward to what future models bring while I collect some lenses for the system. I imagine Fujifilm is listening and a flash system may come along with faster sync speeds and HSS. I have read that the Nissin i40 can be forced to do HSS, but I want a wireless RF system... I am spoiled with the 600-EX-RT's in the canon world. I also use a lot of cheap Yongnuo YN560-III's (and those work fine with the Fuji for what they do).
