    Thats insane. :eek3:

    I wonder what makes canon and Nikon ones more expensive than say, Sigma or Tamron. Is it just a name or is it actual quality of the glass. :dunno:

    The former probably has better: glass, diamond cuts, construction, and polishing time. Or maybe it's just a placebo effect :dunno:

    I have that 24-70... I like it a lot. I'm curious how much better the Nikkor version is though and if its worth the extra $1300 premium over mine. :o

    I'm sure its a little of both. I can tell w/ my 24-70 wide open at 2.8, some pictures come out a little soft compared to my 70-200 VR. Not that they're in the same category, but the Nikon one feels like it takes crispier pics. :dunno:

    I just don't know about the pricing on some Nikon stuff.

    Hows the sharpness? It won't matter for me since I need a body upgrade before I can use it, but lens prices don't exactly shift a bunch over time, and I'd be buying both at the same time as an upgrade to my puny d40. (waiting for the d80 replacement)

    its a sharp lens. It "says" to be a Macro on the box, but I guess I haven't really messed w/ it to see how it is close up. I use it a lot more for walk around lens than my 18-200. And it usually stays on my camera as a primary lens for weddings and such. :o
