Nothing is perfect though! Much as I like my 100-400 Mk2 I really miss the "Trombone" zoom of the Mk1. This was much faster and more intuitive also the twist zoom of the Mk2 means that your left hand has to stay in one place - bad for balance. )
Mine zooms both "trombone" and the 'twist' too, I know that people mentioned that they didn't have the zoom on theirs, but mine does, I can't say that it always did, but it does now. No creep either...
