Good value even if you don't own a Nikon.

That depends on the wildlife, and location, but I am getting ahead of myself.

First it is a $800 70-210mm f/4, and that is undoubtably a good value for a
FF 200mm zoom, but at that price is not a particular bargain for that spec
lens. I would only fully comment on its capability once there are a few
impartial reviews. If I am not mistaken I believe you already own a better
lens in the Nikkor 70-200mm f/2.8 (I am not sure which edition). Under the
right circumstances getting out as far as 200mm is OK for some birds and
wildlife in an environment which brings your subjects closer to you.
Otherwise, especially with a FF camera I would look to a lens which would
stretch things out to 300mm, 400mm, or 600mm (with, or without TCs).

For my D300S I still have my Nikkor 70-300mm, and old & slow 80-400mm.

I own a $700 XF55-200mm f/3.5-f/4.8 which does a pretty good job for me on my
APS-C Fujifilm cameras. However, It is not what I would choose for
birds/wildlife to be shot at longer ranges.
