A stylish, lightweight body houses our pressure-sensitive 'throttle' control, which allows you to ease into zooms in either direction, hold a steady speed, or instantly accelerate into a 'crash' zoom. The StealthPZFI is completely intuitive and smooth, requiring no setup, power, or operator skill. This unique miniature control offers unmatched convenience, value, and performance. Independent focus/iris knobs allow two people to operate together for critical focus during moving shots or crane moves-imagine the possibilities! The manual/auto switches lock into position, letting you watch the picture, not your hands.
