Super performance by Tamron
Tamron today introduced its latest lens, the SP 70-300mm F/4-5.6 Di VC USD (Model A005).
It features a new Tamron developed USD (Ultrasonic Silent Drive) motor and a Vibration Compensation (VC) that enables the photographer to shoot at a shutter speed that is an extra four stops slower without having to worry about blurring.
Tamron's USD works with the high-frequency ultrasonic vibrations that are produced by a ring. Energy from the vibrations is used to rotate an attached metallic ring. This is used to create a fast and smooth auto-focus drive.
Availability and pricing has not been officially announced yet. We'll will keep you updated on this.
You can find all details in the official press release by Tamron.
