Just did not want to leave the impression that IR is useless. I love it.
My 70-200/2.8 VR is a blunderbuss, but it is the only way I could
have gotten a crisp shot of a bridge in Japan on the Inland Sea from
a boat on a dark, foggy day, hand held of course. And of course,
consistently sharp shots hand held shots at the equivalent of 300mm.
VR does not make the lens big and heavy it is how fast and well
corrected it is. I also have an 18-200 VR that is only a little
bigger and heavier than most kit lenses, at least until it is extended.
