I have one and it is one great lens. I don't believe I would trade it even for a straight trade for a brand new Nikon 70-200 F2.8. Hope you find a good one.
I have one that I might be tempted to part with as the wife finds it too heavy on her D7200 but I'm not sure what it would be worth. It's in mint condition. Shipping to the US would not be a problem.
Hey Lawrence, from what I have gathered from the reviews I have read, your 50-150 will have better IQ , the only thing you'll gain is the extra reach to 200mm. I know how good your 50-150 is, because I have the same lens.
I didn't notice you already have the the Sigma 50-150mm. This is an excellence lens and I see little value to getting a 80-200mm. If you want more reach I see only a few options open to you. The Nikon 70-300mm, the Nikon 200-500, or the Sigma or Tamron 150-600mm are your best options for zoom, or the expensive Nikon Prime super telephotos.
I'm in New Zealand
I can ship there too if needed
Lawrence, there was one on TradeMe yesterday. Haven't looked today.....
