Of course I agree about auto ISO - I've always used it for dynamic subjects with a fast shutter time (1/1000 or faster, mainly because of moving subjects, which is of course fine also for the longer focals), now I'm going to extend it for static subjects too (on Sony bodies you can see the current value in the viewfinder by half-pressing the shutter button and you can quickly override it by reprogramming custom buttons in several ways). My only point is to guess the slowest proper setting of the shutter time, considering on one hand IBIS+OSS and on the other hand that I've found I've become a bit shaky.
