Digital Quick Zoom
Quick Zoom speed is improved to 0.7 seconds end to end. Quick Zoom provides for a rapid zoom movement to the telephoto position to check focus with the simple push of a button. Releasing the button returns the lens to the previously selected zoom position. Quick Zoom can now be performed remotely from the ERD-T22 and ERD-10A-D01.
