AF performance: D600 vs D7100 (vs D7000)

Many recent comments from D7100 users give impression that it's AF performance is very advanced, almost in D4 league, and better than the D600 AF performance.

Can someone with experience with both D600 and D7100 confirm this, or give some other information?

By AF performance I mean:
1. speed and accuracy of AF acqusition and tracking (sports & action shooting)
2. dealing with tricky situations (tough backgrounds & foregrounds while AF tracking a moving object, etc)
3. accuracy when working with very thin DOF (portraits at f/1.4 etc)
4. AF performance in low light


My impression is that D600 AF performance is similar/the same as D7000 (which is not bad at all), but that D7100 AF is a noticeable step or two ahead for action shooters.

Is that true?

I shot indoor 3/3 soccer with the D600 this weekend. Think U12 playing on a basketball court in a gym. Shooting with a 70-200 VR1. Sitting at the goal where they were running straight at me using AF-C Single point. Even in the dark, shooting 1600ISO at 5.5FPS I hardly missed a shot. When I did, it focused on something which tells me that it was me, not the camera.

I have a D7100, and it is definitely faster than the D7000, but not that much faster than the D600 IMO.

Thanks guys.

Gav, I know about the modules, but modules only tell us a part of the whole story.

That's why I'm asking about first hand experiences D600 vs D7100 AF, preferably by people who used them in the above mentioned 4 areas.

I shot close to 1000 shots of race cars at Road Atlanta on Saturday with the D600. Didn't have any problems with AF there. Planning on shooting at Barber this coming weekend, and have no worries about AF there either.

I don't have experience with the D7100, but I have the D600. Most of what I shoot is concerts/performances/etc. in very low light (e.g. ISO 6400, f/2, 1/125) and although I definitely can't say I get 100% photos in focus, I think it's pretty good overall. I think I'm pushing it more or less to the extreme of low light with moving people.

Occasionally the camera won't be able to focus. This takes even more extreme conditions e.g. ISO 25800, f/1.8, 1/50 and especially with a not very contrasty target. With a clear contrast even in those conditions it can focus sometimes, but not always. This really depends on the exact situation of where what the (tiny amount of) light is lighting, etc.

This is all from my not that great memory...

I can post some examples if interested.

I shoot a d800, d4 and a d7100 and I shoot sports and BIF

The d7100 is as fast as the other 2

It is a freak camera, feels like a toy, shoots like a gun

I must have had the one bad D7100, as far as focusing is concerned. I found it to be inaccurate with AF-A modes and my Sigma 70-200mm f2.8 OS HSM. I'm not entirely willing to blame Nikon though because I think Sigma may have an issue with using the outer AF points. I've seen three newer Sigmas which all back-focus on the outer AF points. My 50mm f1.8D and 35mm f1.8G did not seem to have this same issue. I can't say what it was for certain but I was unwilling to live with using only the center AF point for forever (or send it off to Nikon for some sort of calibration which may or may not solve the problem if it is a Sigma issue).

I have shot some with the D7100 (I own it) and the last few days also the D600.

Yes on paper the D7100 should be better, but for the time being (as mentioned only few days with D600) I have not noticed any difference, and I would say both are great.

The D7100 is a tiny bit sharper.

Well I went from a D7000 to the D600. The AF is MUCH better with the D600. Dont know about the D7100.
