| A new SDM system has been incorporated for smoother, quieter autofocusing operation using a built-in supersonic motor. |
| One option would be to use the precision-engineered rings of piezoelectric ceramic used in stills cameras to move an autofocusing lens. |
| Cells were monitored in an inverted phase contrast microscope with autofocusing controlled by dedicated software. |
| For his dissertation topic, he decided to see what it would take to devise a new type of lens that would make autofocusing work better. |
| Because a dedicated flash's output is mated to the autofocusing system, the camera even knows how far away your subject is. |
