The new Tokina AT-X 70-200 F4 FX VCM-S (70-200mm f/4) is featuring a new Vibration Correction Module and ring-shaped ultrasonic style auto-focus motor. This lens is designed for digital cameras with full sized sensors as well as APS-C (DX) sensors.
The Tokina AT-X 70-200mm lens is the first lens with Tokina's new proprietary VCM (Vibration Correction Module). This technology allows for up to 3 stops of vibration correction* to reduce the affect of camera shake in situations were a tripod or monopod cannot be used.
Additionally the new 70-200 Lens features a complete ring-shaped ultrasonic motor for faster and quieter auto-focus. This new motor allows for the minute adjustments between AF and manual focus modes dramatically increasing operability. The "S" denotes the new ultrasonic motor.
The optical design of this lens has 3 SD (FK01) Super-low Dispersion glass elements to correct for chromatic aberration and maintain heightened optical quality throughout the zoom range.
Tokina's announcement of the AT-X 70-200 lens expands the lens lineup to include a compact high-performance telephoto zoom lens that has great portability in a professional caliber telephoto lens.
