I'm lending my 70-300mm VR to a friend with a D5000. The 70-300mm is refusing to auto-focus on the D5000. I don't have a D5000 so I don't know its settings or anything, and I don't have my own camera with me to see what might going on. But as far as I know the lens works fine. Anybody know what could be going on?
_________________________________ A little knowledge is a dangerous thing
The VR version of this lens was only made with the AFS built in motor. It should work fine on a D5000.
LaDonna, Make sure your friend has the D5000 set to one of the AF modes which can be set by pressing the i button and setting the mode in the LCD screen. Also make sure the M/A-M switch on the lens is set to M/A. If that doesn't work then let us know.
A simple question: Does the friend have a AF lens that is working normally with the D5000?
If the answer is "yes", I cannot help you. Should the answer be "no" because that friend has no AF lens, then your should: check menu configuration and check the AF switch on both the camera and the lens.
You might want to verify that all of the electrical contacts on the lens project out the same distance. They are spring loaded and can get jammed in, possibly causing AF to malfunction. You could also use a drop of DeOxit on a Q-tip to clean the electrical contacts just in case they are oxidized.
