accessories: for shutter release currently only rr-90 is available (Very bad), limited choices for cases, thumbs up/ shuttle button not available
Wifi: cant use tablet as remote control as display( maybe in the future?)
However the auto-iso works very well, af is fast and accurate(mostly), whole camera feel more responsive, IQ still as amazing, its small, light and come with auto mode even my sister can use. 95% of the time it work well for me but the shutter still abit too loud to be discreet. However if im the only user i might consider waiting for the successor of xe1 that i heard is coming around the corner.
I believe there are other remotes, I believe if it's the same like the xe-1 u can use canon remotes on it.
