"D7000 Focus problems"


Ellington, US
          

I have taken over 27K sharp pictures with my D7000, but lately it has been slow to focus--if it focuses properly at all. Pictures are coming out clearly out of focus. They're sharp enough to pass the "chimp" test on the camera's monitor in that they would appear to be sharp (although I didn't zoom in on them to inspect them), but when I put them on my computer for processing, then its clear just how out of focus they are.

Question: someone suggested to me that I clean the contacts on my camera body. I suppose the theory is that over time these electronic leads get dirty and interfere with the camera to lens communications. How do I clean these leads?

Any other suggestions other than the electrical leads needing cleaning?

It's late, I am going to bed, so I don't feel like finding samples at the moment. I will do so tomorrow if necessary.

I know your pretty experienced so please excuse the silly question.

Have you changed any of the programming ? the reason I ask is that I had a similar problem, and felt quite the fool when my camera store tech reset a bunch of things and it went back to tack sharp again, in other words I had played with too many settings I misunderstood the meaning of

Lol! Good question. In my experience, no amount of experience shields one of something like this.

I did play with the "Focus correction" feature of this camera in hopes of solving the problem--to no avail, of course. And I reset my settings back to their default. I suppose it wouldn't hurt to reset the entire camera to its default settings and see what happens.

James,

Use a good contact cleaner like DeOxIt. RadioShack used to carry it but it is my understanding that they've discontinued it. Find it, or a similar product in a place online or not that deals in electrical or computer products. Do both camera contacts and those on the lenses. This procedure can't hurt and may well help.

Thanks, I'll Google that product and see where I can find it. I hope dirty contacts is what the issue turns out to be rather than a dying focus motor inside the camera body. I took twice as many pictures with my D70s and that focusing mechanism is still going strong. We shall see, and I'll be sure to update this thread with my findings.

Hi Jim,
I'm just going to echo mudman's suggestion. I was wondering about my on D7000's focus at one point just before the warranty expired. I took it into Nikon service and they gave it back to me saying that they could not adjust it any better but they had cleaned it and reset the whole camera back to factory specs. The photos were tack sharp. I took it home and ran through my lenses at different lens settings and realized that AF Fine Tune had to be done to get the sharpest results. It was a lot of work but I am getting shots as sharp as my new D7100 now. So don't give up! You've certainly got a lot of use out of yours!
Cheers.

After discovering having focus problem with my D7000 when photographing birds I reset my camera 2 green buttons before taking camera to Nikon for check up. Nikon service checked the camera and was found to perform to specification. Nikon said 2 button reset would fix this problem. Also reset the custom settings in the menu. It did in my case and the camera is now working well.

Hi James, the focusing issue can get confusing if a lot of things are tried randomly without reducing variables.
First off, before even thinking about it, do not use a pencil eraser or worse, an ink eraser on gold plated contacts. It can't do go and can do a lot of damage and assure less reliable contacts for the remaining life of the camera. Using a tiny amount of de-oxidizing chemical as suggeted can prolong the useful life of the contacts and prevent future oxidation for about 6-12 months following each application.

But getting to the problem....the contacts are not likely to be the cause of your focusing problem. The communications between body and camera is digital and will cause an error message to be displayed if there is communications problems.
First step, reset the camera so you know what all the settings are, when one buried menus item otherwise might be throwing you off.

Next, try Live View. Does it focus accurately?

Do all your lenses cause the same missed focus. If not, are the problematic lenses wide angle?

Does the green focus status light up in the lower part of the viewfinder. If you focus manually, and get the Green light steady, is it still out of focus when zooming in to 100%?

Are you doing your tests in AF-S, if not switch to that mode. To reduce another variable in the evidence gathering, be sure the tests are done in good light.

Try this and report back the results and it will point in the direction to look further.

The question about the focal length of the lenses showing the problem is prompted by the fact that wide refraction angles are harder for AF systems to compensate for phase differences. An AF adjustment problem usually shows itself first at wider angles.
