Ok.... got mine (Pitman Photo, Miami) a few hours ago, serial # 3017XXX -
So far it is PERFECT, cap on live view High ISO, NO hot pixels. I have tried three different lens, off and on a number of times and lots of varied focal points, a Tokina 11-16 / 2.8, a Nikon 50/ 1.8 and an old manual focus 80-200 macro, ALL are working perfect, except of course the 80-200 doesn't auto-focus (duh!). Very Sharp and great low light work. So far VERY pleased!

Not enough to bother me, as long as the photography side (What I bought it for) is working right. Of course I'll still enjoy my video also, it will be great for anything I would do.

I sent some pictures that I took while having AF issues to Nikon and they should be back to me within 24 hours to let me know what they think is going on. I viewed some of the pictures from a recent shoot in ViewNX2 and the camera data on pictures taken within seconds of each other switch from AF-S to Manual???
I'll keep everyone posted on their response.Posted 2 years ago # -
Please use the Bad Pixels thread to discuss that topic. We don't want this thread filling up with 15 pages of pixel discussion too. This thread is for other D7000 "problems" new users may be experiencing.

Received my d7000 body about two weeks ago. I noticed that it wasn't as sharp as my D70. After a bit of testing, I concluded that it has a back focusing issue. I dialed in a -5 AF Fine Tuning adjustment for my 18-200 VR and it fixed the issue for that lens. Unfortunately, I've already dialed in a -20, which is the max, for my 50 1.4 and it still had a back focusing issue.I wanted to test with my 70-200 2.8 but I'm afraid I'm running out of time. I took the body to Nikon's El Segundo repair center today. I should know in 7-10 days if the issue is fixed. If not, back to Amazon it goes.
UPDATE: I got the camera back yesterday from Nikon Repair Center. Initial test shows the same issue. My 18-200 still needs a -5 adjustment. the 50 1.4 looks better, only needing about -10, not more than -20 as before. I still have to do a thorough test this weekend and decide by Sunday if this goes back. Weird that Live View focuses TACK SHARP! And according to the manual, Live View doesn't use the AF Tuning function. I wonder if this will be fixed by future firmware update. BTW, I also found one blue hot pixel.
My serial number is 31xx.

How does one determine if the camera has a back-focusing issue? The reason I ask is because for the first several days I had my D7000 and looking at the images on my computer monitor it looked like all of my images were soft. I was ready to take the camera back and/or exchange the lenses. Yesterday I printed a few shots for the first time and all images were tack sharp. I was like WOW! Maybe I need to update my monitor.

In live view the mirror is up, therefore the split-phase AF points are blocked, so the camera is using contrast-detect AF.
Contrast-detect AF must over and under-shoot the focal point in order to verify where correct focus is. It matters not a red cent how far your lens or flange depth is out of calibration, as CD AF doesn't need to know these things to work.
Phase-detect AF actually measures how far out of focus a line pair is, and moves the lens directly to the calculated correct position. This can only work if every piece of the equation is known, since focus is not verified (as in CD), but rather measured and applied. A flange depth 0.4mm out of tolerance means the system as a whole will always be off. A lens misreporting its focus helicoil position likewise will cause a consistent error.

Anybody have problems with live view focusing with the D7000 using the tamron 17-50 non-VC? This combo just doesn't seem to be working at all for me. When initiated, it is close to being in focus, but then just gets futher and further out of focus while I half-press the shutter. Then, I point at another object at a different location adn distance and nothing happens, doesn't even appear to be attempting to focus.
(live view focusing works fine with my Nikon 35 1.8).Posted 2 years ago # -
Hi guys,
I'm having trouble using the AF point selector to auto-focus the lens.
The lock switch is off, I pick the point I want to focus but the camera just doesn't do anything when I try and take the photo. Any clues?
The switch on the front left is set to M, correct?

Experienced the same issues with both the 35mm f/1.8 and 24-70mm f/2.8 - both less than a month old.
What you guys need to look for: Does your AF icon show single point mode on the top display when this happens? Mine does, and changing AF mode or points is impossible as long as the error persists.
Not sure if twisting works as it has been a bit of a hit and miss - seems waiting has been the only thing working for me.
Incidently: Seems to happen more when I am out in the cold air (-3 to -5 degrees celcisu), than when I am inside. This could be an indicator of poor contact between the body and lens.

Is anyone having problems with the autofocus on their D7000? On several occasions I noticed my lenses would not AF at all and I couldn't figure out why. After fiddling around with the settings and changing lenses, I noticed there is some play/slack after the lens is locked in place. I finally discovered that if I twist the lens clockwise after locking it in place the AF seems to work fine. I'm talking about twisting it just a hair.I have four lenses and they all have exhibited the same condition on the D7000. So I check them out on my D70 and they have some play as well, but I've never had any issues with the Autofocus.
Has anyone experienced this?

thanks every one...
But Please lets focus on the HOT PIXEL issue.
we need to figure out this problem is hardware or just firmware?.
and is it safe to buy the camera now or wait????Posted 2 years ago # -
ahmedtaha you're the one who's in the WRONG THREAD! LOL

On my first D7000, which I returned because of a dead pixel issue, I had some autofocus problems where it wouldn't autofocus and the focus mode indicator on the top display would change to single point, if I remember correctly.
Switching the focus mode selector switch back and forth a time or two would reset it to the way I had previously set it and everything worked fine.
I had the camera for about a week and used it quite a bit, this only happened 3 or 4 times.Posted 2 years ago # -
I am also having the autofocus issue. D7000 serial number is 3011xxx. Camera will be working fine and then suddenly will not autofocus. When this happens, regardless of what AF area mode I was in, the AF-area icon in the camera's control panel will show the single dot, indicating it thinks it is in single-point AF. Toggling the Focus Mode Selector level on the camera (by the lens mount) gets the autofocus working again, but it is still very frustrating. This has happened maybe 10 - 15 times, and the camera taken 2,000+ photos. It seems to be happening more frequently lately. The issue has occurred with the kit lens, as well as an AF-S 35mm 1.8G and an AF-S 10-24mm 3.5-4.5G.

I also have similar liveview autofocus issues. I will get a green square for a fraction of a second, then the liveview goes blurry and refocuses somewhat but remain with a red square and not fully focused. This happens in every modes, with my 18-105 VR, 70-300 VR and my 35mm f1.8.
From what I can see, and I have not tested this extensively, it happens under home type lighting in the evening (but I'm sure that these condition cannot meet the low light conditions as there is a few light sources on). Throught the view finder, all seems to be ok.
Is this fixable through some settings I'm not familiar with? Can AF fine tuning help?
This is my fist DSLR and don't know much about live view. Is this a frequent issue (if at all) with other Nikons? Can this be fixed through firmware or is this hardware?
I should have some time on Monday to call Nikon and speak with a technician.
I still love the thing very much and would not return it, except for repairs if this is found to be a manufacturer's defect.
And BTW my serial number begins with 5001...
Thanks

Hi there
Thanks for these posts, its helped. I bought the D7000 & Nikkor Micro 105mm lens 2 weeks ago. Took it back with focusing problems a week. Fairly random - I cant pinpoint it to any particular circumstances/conditions. The service guy at the shop thought it was the lens so he ordered me a new one. WNow I've tested the new lens & it still happens but now it happens with my 18-70mm Nikon kit lens too. When it happens, pressing the shutter down half way does nothing, it just remains unfocused and changing the focus from close up to distant things makes no difference. You all seem to have experienced it in one way or another, but has anyone had it fixed yet - is it a camera replacement thing or a software update thing? The store policy is it has to be returned in 7 days for a replacement, otherwise it will be fixed instead, but as it was ID'd as a lens problem, its now 14 days since I bought it. Thanks,Posted 2 years ago # -
My current autofocus fine tune settings
60mm 2.8 -6
35mm 1.8 -6
11-16 2.8 -6
18-105 0
70-200 2.8 -12clearly my camera has atleast a -6 backfocus
the kit lens is a tough one to identify, it has very wide depth of field so I am unable to find out clearly if its out of focus.
should I return this camera or just live with these fine tune adjustments ?

First post but love this site.
So far I've had no issues with my D7000. Focuses right on and no bad pixels.
Until today I noticed the Tamron 17-50mm I just got was searching a lot in darker areas. As it turns out it was because the AF light would not turn on to help the lens focus. I looked in the menu and it turned on. I tried the lens on my D40 and the light works as should with no problems. Then I tried the D7000 with my Nikon lens and the light worked fine. So my AF light seems not to work with aftermaket lenses. Anyone else experience this? Is there any new firmware out yet I should try or what should my next action be? Thanks.

AF assist turns off after a while to avoid overheating if it's in constant use. I don't see how it would turn off completely only with third party lenses. The D7000 just came out so there is no new firmware for it.

I'm looking to buy a new Nikon (since I've had D50 for 6-7 years for now) and D7000 looked like the best option, but all the problems I heard in different forums have made me little bit hesitant.
Some hot pixels is kind of given with digital cameras, but is the focus problem something that's easy to fix or deal with or is it more serious issue??? I am not in a super big hurry - would like to get a camera by new years'. Is D7k worth the money or should I look into some other Nikon cameras (I have quite a few DX lenses for Nikon already and a flash as well - so don't want to jump to canon or pentax etc.)
Thanks,Posted 2 years ago # -

How does one determine if the camera has a back-focusing issue?To test the focus just take a shot of objects lined up ... take 5 toothpicks, focus on the middle one and check the result. Or you can use the chart (and explanations) in this PDF file http://focustestchart.com/focus10.pdf or this one http://focustestchart.com/focus21.pdf The latter is a newer version.

Thanks Drab and Monty. I haven't done those tests yet because I'm pretty much convinced that my camera is focusing just fine. I'm getting sharp images with all lenses (Nikkors only so far).
Best regards.
