There is no proof that D600/601 focusing system is any different than the D7000's. Nor I have ever seen all discrepancies stated on this site regarding D7000 focusing. My D800 is slightly faster, able to focus in darker and has more & wider spread. In everyday I see no difference unless critical work.

Specs, as per Nikon:

D7000 AF module: "Multi-cam 4800 DX", 39 focus points including 9 cross-type, sensitivity -1EV to +19EV

D600 AF module: "Multicam 4800", 39 focus points including 9 cross-type, sensitivity -1EV to +19EV

Df AF module: "Multicam 4800", 39 focus points including 9 cross-type, sensitivity -1EV to +19EV

D800/E AF module: "Multicam 3500 FX", 51 focus points including 15 cross-type, sensitivity -2 to +19EV. In other words the D800's AF engine is TWICE as sensitive as that on the D7000 or D7100 or D600 or D610 or Df. Which can be a pretty big deal.

Interestingly, the D4s apparently also uses the 3500FX but has a range only from -1EV vs -2EV on the D800/E. So it seems that anyone who needs to regularly AF w/o assist light in ow light conditions, is better off w a D800/E.

And how do other brands compare?
- at Canon the most sensitive AF engine is on the 5D3, 61 points o/w 41 cross-type, sensitivity -2EV to +18EV

- at Panasonic, i.e. mirrorless, the GX7 can AF in as little as -4EV. In other words the humble GX7 can focus in as little light as 4 TIMES LESS LIGHT than a D800/E can. And, 8 times less light than a Df / D600 / D7100 / D7000 can. Ouch!

Buy the GX7
