Calibrate nikon D7000 to my two Nikon lenses
Jun 20, 2015 12:43:51 #
I would like to calibrate my Nikon D7000 to my two Nikon lenses, 24-120mm f3.5 - 5.6 G VR and 70-300mm f4.5-5.6 G VR. I searched for previous entries; but found nothing. I'm looking for something simple that will get me close to dead on. Are there any simple apps or procedures that could help?

Not surprising. Calibration has been discussed here many times but the Forum search is not that good. I often get better results from Google by starting the search words with Uglyhedgehog.
Here's a Google search for "uglyhedgehog lens calibration".

Larry B,
Thanks for the info. I now have a weekend project to determine if my image sharpness is a user error or a manufacturing problem.

Now the fun part. Some will tell you that you can only fine tune prime lenses (non-zoom). Not true but the problem with zoom lenses is they front or rear focusing can vary thru the zoom range. F'rinstance, I have one lens that needs plus correction at one end of the zoom and minus adjustment at the other end. :| And Nikon will only save one setting for each lens. :roll: Best you can do, if adjustment is needed, is to calibrate for the focal length you use most (probably the longest length) where focus deviance will show the most. Or do what I did and stop using that lens. LOL. Good luck.

I use the DataColor SpyderLensCal to calibrate the lenses on my D7000. It's a little pricey but you can see if your camera/lens combination is back or front focusing.
Check out the website that jeeryc41 listed above:

The procedure described in that article compares photos taken with your camera in phase detection and contrast detection autofocus modes. Your camera uses contrast detection autofocus when in live view mode. There are no AF errors when the camera is using contrast detection because it adjusts the focusing until it has achieved the highest contrast on the sensor. There are links for two targets that you can print out in the article.
