Features Advanced VC Mechanism Highly Evaluated for Its Hand-shake Compensation Performance
The highly evaluated VC (Vibration Compensation) mechanism originally developed by Tam-
ron delivers exceedingly stabilized viewfi nder images for remarkable hand-held photography
without annoying motion delay. The VC mechanism exhibits its camera-shake compensation
performance to the maximum extent at dusk, in dimly-lit indoor situations, or in hand-held
shooting at the ultra-telephoto settings.
