It's so hard to judge performance based on those photos. I'm assuming the "RAW to jpg" shots are all uncropped, sooc. What I find interesting is that on the longest reach, most radical crop (last photo) he chose an image shot at f/10 and ISO 6400, while the rest were at max aperture, f/6.3. So you're compromising my ability to judge sharpness by introducing all that noise. Did you not give us an example at f/6.3 because you couldn't get one in sharp focus at that distance? Regardless, it seems to be a decent lens, but nothing brilliant. Having lived with my Sigma 150-500mm for almost 3 years now I'm not seeing anything here that is in any way sharper than what I get out of it. At best these shots are "as good", but that comparison is drawn against no images from other lenses on the same sensor, just my own images against Nikon sensors.
If I learned anything from the review it's that I'd much rather have a D610 at 2/3 the price than the 5D Mk iii, if only for high ISO.
