Same sensor if you're good enough to need a back-up...the crippled controls
on the D5100 will make you rip your hair out AND no AF fine tune Stick with the D7K
Ok, Nikon got one change to fix the replacement camera otherwise I will either get another camera type or maybe even just skip that and get a lens instead. Or get it refunded, hopefully Nikon can fix the problem though.
I don't remember My Nikon N6006 back focusing nor my F 6. Why all of the sudden a camera that does not focus properly. Isn't it a new and improved AF. The old film AF cameras didn't even have the means to micro adjust the focus, but they put that in to the D 7000. Almost like they knew there would be problems.
Someone should do a survey to see what percentage of the D 7000 have this AF problem.

I think the reason that Nikon added AF fine tune to the D7000, is that having 16MP on a crop sensor is really going to show up even the slightest focusing inaccuracy when viewed/printed at a reasonable size and the type of shooter who buys a D7000 is more than likely to do just that.
Unfortunately the results of any survey will be skewed by those who don't know how the AF system in the D7000 works. I've seen numerous posts on various fora from people saying that their D7000 has 'backfocus issues'. Almost always it's because they're shooting in AF-A, or they're shooting moving subjects in AF-S or using AF-C 3d incorrectly.
And before anyone wades in and flames me, I'm not saying there aren't any issues, just that the percentage of real issues is much lower than people think.
gfinlayson, there is something unusual going on with the D7k production from Nikon because I'm not hearing or reading anything about similar problems with other camera models from Nikon. Nikon just need to fess up that there is something wrong and fix it!
I'm user of Nikon DSLR camera for 6 years so I know my way around the AF system. My old Nikon D80 is working perfectly in all focus modes and with all lenses I own so it is defiantly the D7k body which is causing problems.
My D7k body could maybe get such focus like in your photograph in maybe 10-20% cases, which I don't think is acceptable. In other words, I need luck to get correctly focused image.
Good luck with getting yours fixed. As trenchmonkey said above, when it works well, the D7000 is hard to beat. Please let us know how it goes with Nikon
If it's a function of the large number of pixels, then it should show up again in the D 800. Or is it that the users are not that experienced? I think for $ 1200 there would not be many inexperienced users of the D 7000.
The focus on mine was so off it would be off even on a 4MP body. You could see it in the previews in LR which are much less than that. There was really nothing subtle at all about it.
After some unsatisfactory conversations with the dealer and reception at Nikon, I fronted the Nikon Service centre on Thursday afternoon complete with CD of the problem
All sorts of execs and senior techs came scurrying out of the back and it is now high priority to fix and by the way, if it is a problem within the lens, it will still be treated as warranty. N/C.
I hope you get this all sorted out, because I think this camera is impressive.
I just bought a used D7K, and I have to say that the focusing is spot on. I'm very impressed with this camera at ISO3200 and 6400 as well.
Like you said earlier, things like this can take all of the fun out of photography. Good luck with getting things right so that you can just get back to having fun!

Stick with the D7K
