  Use at normal shutter speeds and see an improvement in picture sharpness
 
This image stabilisation lens has a newly developed system that can achieve stabilizer effects equivalent to approximately 3 stops in terms of shutter speed. It further has high-resolution, high-contrast optical capability, and dust - and moisture-resistance, making this one of the most advanced and robust models in its class.
