So B&H has this lens for sale for $1350. While I always wanted the nikon version its a steep price for someone who uses it as a hobby.
Does anyone have experience with Sigma lenses/this particular lens or even the non OS version? The non OS version got some decent reviews i found but the non OS version got mixed.
Is it worth the money?
I have several non-Nikon lenses for my D300 but not a single sigma. I never had luck with them, just a personal preference.
If you can get to a local camera shop that has the Nikon and Sigma ask if you can bring your camera, or if they have a demo. so you can play around and see if the saved money = worth sacrificing the construction/optics/af speed of the Nikon.
Once you get above a grand for a lens you may just want to keep saving for the Nikon 70-200 or even try to find a used VRI model on B&H or Adorama for much cheaper.
I have this lens. It focuses about as fast as the current latest and greatest G, AF-S, series lens. I would take a Nikon lens over a generic any day. Image stabilization is only needed if you are shooting at slower shutter speeds, if you are going to shoot sports or in the day light the image stabilization isn't needed. Here is Ken's review, I know sometimes he is very opinionated but his review is spot on with what I have to say about the lens.
