I would want to shoot landscapes handheld if that's all I could do.
Its much much better than NO PICTURE.
VR pictures are softer than the same lens on a tripod. I've become
more and more cynical about VR and think apart from the long
telephotos, it's just a gadget to attract ignorant consumers.
A landscape photo is shot from a tripod. That way you can better
stitch pictures (often necessary given the lack of affordable medium
and large format digital cameras), and combine multiple exposures for
HDR. Also, you get to think about your composition and get somewhat
more detail (just because the camera is not moving and because you
get to choose the aperture freely). It's also much easier to get the
horizon exactly level when you operate from a tripod.
Landscapes without tripod is basically sunday snapping.
I think it is a mistake to not
include VR on these lenses. Why is it on the 16-85 or the 18-55 then?
I think it would be a mistake to complicate and compromise the
optical design of these very fine optics (the 24-70 especially) by
introducing a frivolous feature which is not in line with the fine
quality of these lenses.
Try going to a busy place like las vegas and take some pictures. Are
you going to carry around a tripod at disney to get a good shot of
the castle at night?
Of course one carries a tripod to do still photography at night. Why
would one not?
