Very nice, love Boneyard beach

Image 1(1378) appears significantly sharper on download and magnification. Color very similar on download but the initial image 2 does not seem as vibrant.

Just saw ad for Nikon 810 for preorder at BH Photo

I have the Nikon 70-200 AF-S VR ED 2.8 and a TC-17EII. I am trying to decide whether to buy the Tamron 150-600 or sell the Nikon 70-200 and buy the new Nikon 80-400. I am interested in birds in flight. Comments and experiences appreciated.
