It has the same AF as the D4 and significantly better IQ at low ISO compared to other cropped sensor models. It too is crippled with a small buffer size, but the AF is not bad. It handled the stilts quite well.
The smaller 24M pixel sensor of the 7100 will never compete with a full frame sensor for low noise at higher ISO. I would love 24Mpixel FF with the same AF spec's as my D7100. For me, IQ has always trumped AF speed but now I am not sure.
