Tamron has announced the development of a new fast, optically stabilised, splashproof standard zoom for full-frame cameras. The Tamron SP 24-70mm F/2.8 Di VC USD will feature the manufacturer’s Vibration Compensation (VC) technology and an ultrasonic focus motor for quiet AF operation. The optical formula comprises 17 lens elements in 12 groups, including three low-dispersion, two high-refractive-index and three glass-moulded aspherical elements as well as a hybrid aspherical element; and an iris diaphragm with nine rounded aperture blades. As the world’s first 24-70mm f/2.8 lens with VC technology, the Tamron SP 24-70mm F/2.8 Di VC USD will be available in Canon and Nikon fit. A special A-mount version with no Vibration Compensation will be marketed to Sony DSLR users. Pricing and availability to be communicated.
