How does IQ compare to an old D200?

Hi all,

I own an aged D200 and I'm looking for some lighter equipment with enough (300mm equivalent) reach. I do own a Nex 5 too which is great for low light, and I tried the 18-200 for the NEX but I found it far too bulky and sold it because I lost too much of the advantage in size and weight compared to my D200.

Since I'm quite happy with my D200s IQ: How does the (modern) Nikon 1 compare to the aged D200 IQ wise? Any comparisons?

Thanks in advance!
Martin
