Thanxs for the link.
It seems, the HDR function works like I thought it would. This is a very nice little feature.
Better yet, the three shots appear to be fired within one mirror swap period, so may be instanteneous. If this is true, SR should really stay on during the operation ... because, the entire shot may just take as long as the single one at +3EV.
Of course, now that it is there, one may ask, why didn't they add automatic alignment between images? Raw shooters do it on a PC and JPG shooters may not carry a tripod
2 GB memory and the horsepower of the new in camera processor would have certainly coped with it.
But as always, once a feature is there, one can always ask for even more
