Nikon would not complete focus even manually

While on Darwin recently, My Nikon D7000 stopped focusing correctly.

It would focus to a point and then stop with even manual focus impossible. Switching the lens to another camera showed that the lens (Nikkor 80-400mm, 4.5-5.6) was not the problem and using a different operator showed that the problem was with the camera.

I made a hasty visit to the camera shop (ready to buy a new camera if necessary) where they found the same problem. Resetting the camera (I had forgotten about that) corrected the issue but I still do not understand what was the root cause although there was some mention of the ISO setting.

Has anyone else ever had this happen? The previous day's pics were not too bad but it was dusty and we were in and out of the car. What setting could I have bumped to cause this problem?

Any help appreciated as I could only fleetingly admire the female Shining Flycatcher which posed in front of me at East Point rather than capture her image!

I doubt an ISO setting would cause your camera's AF to fail. If they had to reset it to factory standard then perhaps drop it in for Nikon to diagnose. These electronic devices are a real pain in the rear.

Thank you, I could not see how an ISO setting would cause such an issue. It has not re-occured but sounds like a good idea to drop it off for a check. I would not like to be in that situation again.

The iso settings should not affect the focus unless you use the extended menus for the ultra high iso's ,something that would be hard to do by accident, more likely the camera was in relese mode which allows it to fire weather its focused or not,  the 7000 has a couple of anoying little glitchs that can be easily corrected by updating your firmware.

Sue on some of the longer Canon Lenses you can set the focusing ditsnce from zero to infinity or for example, between 10 metres to infinity to aid focusing. I just wonder if you had accidently moved that switch to a different setting?

I'm not familiar with your lens so this may not even be possible on your lens but sometimes it can be the most simple of things.

Manual focus overrides any limiting switch functionality. And I doubt the cheaper zooms/teles lenses have that function at all. I know Canon's lenses don't.

Hi all, thanks for the comments.

The first thing I checked was that the focus was set zero to infinity'' so that was not the issue. Also nothing was locked. When speaking with Nikon Australia today, they suggested resetting was the solution and that the problem was uncommon. I was planning to put lens and camera in for fine-tuning (something I find difficult) so will get it checked out at that time.

Hi Sparrow, as to updating the firmware, I did not see an upgrade on the Nikon website. However further searching has revealed it so I will also get that done.

Hi all,

Just got the camera and lens back from Nikon. They have adjusted the lens as it was front focussing and fine-tuned the camera as well but no other issues apparent. Hoping to test it all out soon if the weather holds. Cold and damp in Sydney.

Burgled about 2 weeks ago and lost 2 lenses: Nikkor 300mm F4 prime and a Sigma 150-500mm F5-6.3. On checking replacements (depending on insurance company) there is a new Nikon 300mm lens which is apparently magic and half the weight of the old one. I am also told the Sigma 150-600mm is fantastic especially the pro version. I think replacing the lens might win over the jewellery.

Sorry to hear about your burglary Sue.
