The OP camera could not achieve AF for some reason because the OP has problem only when in AF
I have the D7000 and use A aperture priority mode. I set the depth of field. Depending on the subject will set the autofocus to be af-S or if moving subjects to af-c the camera always works when I push the shutter. I never use any of the preset modes like landscape. If I am shooting moving subjects I will use S shutter priority.
Hi,
Wow - once again a lot of great responses - thanks so much!!! I will check out the release options you mention - I didn't see it when I was searching.
When I referred to switching to manual mode I meant switching the lens from autofocus to manual.
I hadn't thought about the focus needing to be pressed half way before shooting - in my excitement I could imagine just pressing it completely down - I'll test that one out as well as the rest.
Once again, thanks so much for all the help!
In continuous mode, I leave the focus in the menu set to release, In single shot I use focus
I bought a refurb 70-200 IS II recently from Canon...worked fine for a week, then it started freaking out...you could hear the AF going back and forth nonstop...and woildnt take a oic...even when switched to MF. Any suggestions? Is this similar to your problem?
Check for a screw loose behind the viewfinder, then read the instructions.

You do not have to press the shutter halfway, stop, then press the shutter fully to take a photo. When you press the shutter halfway down the camera starts searching for focus but it continues to search for and attempt to lock the focus when the shutter is fully depressed. What happens next depends one of two things.
1. If the shutter is set to 'release' it will take a photo eventually even if it can't achieve focus.
2. If the shutter is set to 'focus' if it can't achieve focus it will eventually give up and won't take a photo. When this happens I release the shutter button and try to refocus on an area with more contrast.
