1. I'm not using PayPal to get or pay money  -_-
   
2. tonight I saw a Canon version for 1100.- Swiss francs, the guy was selling it because the lens was not fast enough for him in terms of wide open aperture (but actually Sigma doesn't make a secret out of the f-stops...)
   
3. If I'd sell mine, there's the additional foot and the converter for which I don't have a use anymore once the lens would be sold.
   
4. this evening I made a quick and dirty comparison of the Sigma 150-600 and the Fujinon 100-400. At 400mm and DX mode of D810 they are equal (to me). At 600 mm and FF compared to 400 APS-C there are differences, less in sharpness, more in noise of the sensor.
