    AF Fine Tune = A Band-Aid?

    I've had my D7000 for about 2 months, and I have always had a little trouble getting it to focus where I want it. I chalked it up to camera shake, subject moving, user error, lack of knowledge about how the AF system works compared to my old D40, etc.

    I'm starting to become very frustrated with the focus errors which I'm starting to think aren't entirely my fault. I'm having the most issues with my 35mm 1.8 and 50mm 1.4. Even with a tripod and a stationary subject, settings at AF-S and single center point, I'm consistently getting back focus. I hate to even jump on the "AHH My D7000 backfocuses!" train, and I'm wondering if it's an issue with the body of the camera or with the way it works with the lenses.

    I've played around with the AF Fine Tune, and have to set it at -20 for both of those lenses in order to pull the focus to where I want it. Considering that's the limits of the Fine Tune system, I'm thinking there's a bigger issue than just a little needed calibration.

    Am I being too nitpicky? I paid a lot of money for this camera, and I'd like it to at least focus correctly! I feel like just fine tuning the lenses to -20 is a band-aid for what could be a real problem. But maybe I'm overthinking it.

    (And yes, I called Nikon, and they just said to send it in for repair, but when things are broken, I like to know why!)

    I'd say if you have to set the "fine tuning" for -20 for both lenses, just send it in. Turn around time is about 10 work days and you'll then start enjoying your excellent camera without the worry.
    I've had mine for over a year and didn't have that problem.

    what apertures are you using when you fine tune the focus? people have trouble when they set fine tune wide open.

    I use the lens wide open. Why would they have more trouble wide open I wonder?

    Why would (should) you need to fine tune? It does sound like a band-aide. I have the D5100 with the same sensor and all of my shots have been razon sharp since day1.

    Wide open - I know that images are sharper when stopped down, but I do use my lenses wide open. I shouldn't have a focus problem when shooting wide open. (Right?)

    You should not be having this problem, especially since you stated it does it even when on a tripod, do as Marcel said and get it sent in. The 50 mm at 1.4 has a super narrow DOF but if it is a consistent problem something is wrong.

    Nikon is having me send in photos first so that they can say whether or not it's a back focus issue. Hopefully this is the first step toward getting this corrected.

    I'm curious about this AF Fine tune I keep reading about. Is this feature available only on the D7000? I don't seem to have anything like this on my D200. Just curious.
