Originally posted by Scintilla I'm no optics expert, but any feature that allows me to get handheld shots like
this and
this?
I can only call that the best "marketing ploy" ever.
+1. Pentax SR is one of my favourite features. Since my thirties, I've noticed I'm less and less able to hold things steady (I first noticed it when shooting), even using good techniques for stance and grip. If it weren't for SR, a lot of my photos wouldn't have turned out very well, or I'd have been forced to use shutter speeds that would have required unappetisingly high ISO settings.
My Hasselblad has Sony's "SteadyCam" IBIS, and it's also very good - though not quite as good as Pentax's implementation...
