The Tamron SP 150-600mm f/5-6.3 Di VC USD Lens for Canon is an expansive telephoto-zoom lens designed for both full-frame and APS-C-sized image sensors. Its 4x zoom design covers standard telephoto to super telephoto perspectives, making it ideally suited to working with a wide variety of subject matter. Benefitting this range is VC (Vibration Compensation) image stabilization, which helps to minimize the appearance of camera shake to enable the use of longer shutter speeds or smaller apertures when hand-holding in low-light conditions. A USD (Ultrasonic Silent Drive) autofocus motor provides quick and precise focusing performance, with high torque, low response times, and quiet operation to benefit both still and video applications. Additionally, a full-time manual focus mechanism enables manual fine-tuning of focus at any point, even when the AF system is engaged.
