Default backfocus D70

What about the problems that seems to accur with the backfocus on the kitlens that comes with the D70.
Are there any D70 owners with the same problem in this forum?

check Seves sample shot: :idea:

Her neck is sharper then her face.
I don't know if it's a backfocus problem. I'm not a pro........

Other shot's are perfect for me. I don't think lot of cameras has this problem. But if you have you can exchange the camera or send it to Nikon to calibrate. Realy great camera.

I don't think there is a perfect camera on the market every brand has pros and cons.

The plane of focus is about at her ears. I haven't paid any attention to the focusing sensor pattern on the D70, but I'm wondering if somehow the sensors that caught her neck area got priority.

If this picture is typical of a back focus problem, it looks like it could be a problem. I wonder if Nikon is going to weigh in on this.

Focus is not with the camera, it's with the lens.

Now you folks have to remember I just got my
D70 and I never posted any photos before, but
feel free to look at the last four photos. And remember I'm just a hack at this stuff.

Onyx, I agree that the lens does the focusing, but the sensors in the camera and the computer determine what to focus on. I don't know about the D70, but the D100 has the ability to do an area focus or to spot focus on the same points as spot metering. Consequently, if the lower spot were selected, it is possible to focus on the neck when you were really trying for the face.

I stumbled into this link on another forum where a fellow from Moscow had some focusing probelms that he didn't feel Nikon repair in Moscow was addressing. He decided to repair it himself.

I'm not so sure this is a good idea, but some of the information is sort of interesting.

The site is slow to download.

I also agree that it is to do with alignment in the camera rather on the lens. The fact is that I returned two D70s to the store. Both of them have terrible focus problmes. Unbelievable but true. I showed about 35 portraits I took to the salesperson, and he immedeatly agreed that there was some thing wrong with the camera and gave me another new one. Unfortunately that has the same problem. Now I want to wait until Nikon fixes it. It is apparent that there was a QC issue with some batches of cameras.

I don't care really. When I pay $1300 I expect it work right away. Don't you?

The link to that russian site is certainly insightful. After reading it, I learned a few things I didn't know previously, esp Nikon's AF technique.

Posts from "that other forum" consistently suggest backfocusing only occurs with the kit lens, and other predominantly DX AF-S lenses. Full framed (aka non DX) lenses don't seem to exhibit focus problems. Hence it is my belief that it is not a camera issue, rather a lens and/calibration issue.

May be there are "spies" at the Nikon QC department and they are doing this.............. :twisted:

Just joking, but if you pay that money you expect a perfect calibrated camera and lens and you just want to go out and begin to take nice pictures..........

If you are not lucky that's another story...
