wow. the difference on the corners of the old and the new are pretty big... thanks derrel!
I have the 70-200 vr1. VR on the 70-200 is 3 stop, not 4 stop as someone said earlier. I recently purchased a 24-70mm and a D3s. I have yet to use the 24-70mm outside of playing around with it when I got it. Also I have no issue with the 70-200 vr1 on the D3s. Definitely wouldn't trade it for the vr2.
on the question of 24-70 vs 70-200 it dpeends what you are shooting, but my 24-70 is on my camera 80% of the time. the 70-200 is a chore to lug around, and you really do lose out on short distance stuff with it. the 24-70 is like a walka round lens on steroids.
as for whether VR1 or VR2. The issues witht he Vr2 would make me stay away from it. plus the VR1 was a workhorse and still is for MANY pros regardless of the softness in the corners issue.
you can still find the VR1 new ( i did) for about $500 cheaper than the VR2

Well, on my D90 my 24 to 70 is a 35 to 105. It's a pretty good range for everything exept animals or far away things like planes and such. You might miss the extra 100mm you get from your 18 to 200 untill you realize that you can usually just walk closer, lol. I find the lens amazing tho. I love how the lens hood actually locks. You won't be dissapointed.
i couldnt decide which one i wanted more so i bought both withina week as well.....
you're gonna miss the versatility of the 18-200 no question. you will also miss the weight of it if you are travelling. i still believe there is still not a better travel lens than the 18-200mm.
the IQ of the 24-70 is unreal. it is so bloody sharp its amazing. you will find you will use your 50mm f1.8, and 35mm f1.8 a lot less as those are usually the sharpest lenses in peoples bags starting out, but the 24-70 is almost as sharp, if not as sharp.
The tele is nice, just be aware if you are putting this on a D90 and below (any plastic body nikon) the 70-200mm is a HEAVY, and the body isn't as strong as the d300/d700 bodies. I have read stories on here of lenses pulling the connector ring out of the body itself due tot he weight. The tele just makes the problem worse as its more weight and more length on the joint.
