I would really love to see how this new 70-200 f4 Nikkor lens will fare as a portrait lens. When this lens is compared to the 70-200 f2.8 VRI at similar exposure settings - how attractive the bokeh will be and color rendition as well as contrast. Being that one could purchase either of these lenses for approximately the same amount of money...I will end up making a choice between one of the two.
At the end of the day - I do not think I can really make a bad decision here, but thoughts and examples of photos whenever someone picks up this new lens would be awesome!
