The V1 setup only workable for me if the subject is stationary, but few wildlife stay immobile for us. When shot at ISO100, often the speed is too slow even if I do my part and the electronic shutter generate hardly any shaking of the V1 camera. Any slight movement of the subject blurs the image.
One may ask how about D4 with 70-200mm VRII and the TC-14E II? The image is soft at wide open f4. It ought to be use at least f5.6, not much better than the 80-400mm VR. 70-200mm is already a very long lens with the TC-14E II makes it even longer and ergonomically difficult to hold as compare to D4 with 80-400mm. 200mm after the 1.4x is really only 280mm, hardly worth the trouble. I always shot 80-400mm on FX camera hand-held at speed as low as 1/100. For speed lower than that, I have to use tripod, turn VR off and use mirror-up with remote shutter release. With even higher ISO performance than my D700, D4 and 80-400mm is really a very good combination for me. May be I can have a 400mm f2.8 with D4, but it will be so big and heavy, people will surround me to look at my camera rather than looking at the tiger.
However, in the wildlife situation, hmmm...... I think the animal's face can be challenging for the camera. The D4 was clearly focused on the flamingo's wing, the eye is clear but a bit soft, especially when I look at 100%.
