Go into the menu system and look at the fourth page from the left. You should see AF mode, second option down. Select this and you will see three options, Live mode, :-) Live mode and Quick mode.

It sounds like you have AI Servo selected for the AF mode. The behavior you describe is normal if that is the case. To do what you want, you need to select One Shot as the AF Mode. Please note that when shooting in one of the continuous drive (burst) modes, the camera will not refocus between each shot that is taken while you continue to hold the shutter ...

There are many settings on the Canon 5D mark III that affect what you see and when you see it in the viewfinder. The camera does have the ability to indicate when focus is achieved over a certain point during manual focus, but only if all of the correct settings that affect the display are selected.

If a picture had to be clicked using ECF, the user must focus his eye on a particular place, and many ...

As you were taking pictures using artificial light the most likely cause of your horizontal line is a small frequency difference between your live view sensor refresh rate and the local power-line frequency. As you were using street lighting there would be a brief period, imperceptible to us, where the scene isn't illuminated - this would cause the band. As ...

Focusing doesn't require changing the focal length of a lens, it changes the distance of (the center of) the lens to the sensor or film.

Short Answer: Yes. All EF and EF-S lenes are compatible with your 7D. You should not have any autofocus problems if camera and lens work well. Otherwise you should check the lens on an other eos (if you can) respectively the amera with other lenses.

If I recall correctly, the auto/manual switch doesn't lock anything. Rather, in auto mode, it just allows your camera body to override the human operating the focus ring. That fact both the switch and the ring are seized implies the lens needs servicing.
