Well, it is said to be as sharp as the 200-400f4 so this comes as no surprise.Nikon 200-500 VR: 4.5 TStop; 22MP resolve on 36MP sensor.Again, I see people trying to justify their decision on lenses. Noting that there is sample variation among lenses, I would guess that there is no practical difference in image quality between an average Nikon 200-500 and the average Sigma 150-600 Sport. Each lens has its pros and cons. I ended up purchasing a Sigma Sport and have to say that I am very pleased with it. Maybe I would have been even happier with the Nikon, I don't know.
I don't mind the extra weight of the Sigma because I mostly use a monopod or tripod with it. And I do like that is is quite a bit more rugged than the Nikon. As far as that 1/3 of a stop goes, I cannot believe that some people claim it more significant than 600mm over 500mm. Neither is all that significant. Well I guess (1/3 stop) 26% is a lot more than 20%. By the way, when I checked my Sigma at 600mm it turns out to actually be about 580mm. I would not be surprised if the Nikon is just shy of 500mm. I also wonder if the actual T-stop difference between the two lenses might not be less than 1/3 stop since the Sigma has a front element that is somewhat large. Of course that is pure speculation.
