Yes, besides the sensor
and perhaps the price - we're all ecstatic about those two, even though I'm not really contemplating a larger camera or sensor
For me the top price is the SR going 5 stops: that's really impressive. I didn't think of how a larger SR mechanism could conceivably be more sensitive, so that was a nice surprise. The other cool update for me is the Pixel-Shift improvement; that must tie in to the Clarity function, perhaps? Good to hear that some blur can now be recognized and discarded.
The rear-LED gymnastics will be a great help to some folks, as will tethering and GPS things. Those aren't for me so much though.
What feature got you even more excited than you were a week ago?
I'm tempted to make a poll of this, but I may not list enough possibilities
so I Just Said No.
