I have tried the 200-500mm f/5.6 AF-S VR on field during my trip to Costa Rica this winter. That was  the perfect opportunity to photograph nature and especially wildlife and see what this lens has in its . I have had a good time shooting with this lens and the quality of the images went beyond my expectations. I used it mounted on my D750 which shows excellent performance in low light conditions and thus was an excellent addition to the lens which has a relatively small max aperture of f/5.6. The pictures have been taken mainly in aperture priority mode. Iso values used are between 200 and 5000, so keep your attention on these numbers since they have an important impact on the overall image noise. The settings of each shot is shared in the captions and a crop is given to judge the sharpness and crispness of the pictures. If you want another field test of this lens, have look at the stunning photos taken by Roy Mangersnes in Svalbard, Norway:

For the persons interested, here's a short history of the lens:
Since 2014 Tamron and then Sigma offered interesting super tele with impressive reach (150-600mm f/4.5-6.3), but Canon and Nikon remained quiet with their semi-pro 100-400mm f/4.5-5.6 L IS USM (II) and the 80-400mm AF-S VR respectively.
In august 2015, Nikon launched the 200-500mm f/5.6 AF-S VR,  which has everything to compete (and certainly beat) its competitors but not enough to cannibalise Nikon’s Pro range lenses because of the lack of tropicalization which is required to shoot in extreme weather conditions. 
In other words Nikon has launched a versatile optical weapon with an electronic comparable to pro lenses (AF-S and VR) but without the mechanical finish that characterise them (and that justify their high price). This is a great opportunity for wildlife and even sport photographer looking for a super tele with excellent sharpness and good focus speed and image stabilisation.
Let’s see the results on field.
