OK another question..I had a Sony A300 and noticed when it was on autofocus,as soon as it was pointed at something there was movement in the lens barrel..Could that because the motor was in the camera body??
With the d5100 i seem to only see the lens focusing when i press the shutter half way..Is that the normal procedure?? Its not suppose to rotate like the Sony did right by just pointing it at a thing..I see in live mode the same thing happens..The motor is in the lens not the body of the d5100..Thanks again |

That's normal and has nothing to do with the motor location. Why waist power focusing until you are ready to shoot?

More correctly, Sony dSLRs (and Minolta SLRs and dSLRs before them) have a unique feature called Eye-Start AF. When you place your eye to the viewfinder eyepiece, the camera will automatically focus. Other camera brands don't have this feature, so with any of them, you must press the shutter button halfway down to focus.
