I am not opening a new post to continue on with my previous post... [this is a different question] I was just wondering how people think a Tamron 18-270 with VC (their version of VR) would compare to a nikon 18-200 VR. How does Tamron compare in general- what is the quality like (now I know this is a convenience lens I'm just asking generally here) how does VC compare to VR, I know they both have almost identical focal lengths (nikon is f/3.5-5.6, tamron is f/3.5-6.3). Do you think that the tamron will focus ok at 200-270mm? The tamron is also lighter than the nikon. Lastly, if the tamron has vc, does that mean it has a built-in motor? [I have a d60 so I need one to autofocus] Lastly, getting a little off-topic, why is the nikon 12-24 so damn expensive? I hear it's the only good super wide angle lens for the d60 but it seems way overpriced... they also sell a fisheye lens for my d60 for cheaper... any thoughts?
