 March 13, 2007: Tamron chose the recent PMA International Trade Show in Las Vegas to release details of two new lenses that will go on sale in Australia in the Spring. The new SP AF70-200mm F/2.8 Di LD (IF) Macro lens is a fast, lightweight telephoto zoom lens that can be used on both film and digital SLR cameras. Developed as a partner to the SP AF28-75mm F/2.8 XR Di standard zoom lens, it has the same compactness and speed. Internal focusing allows use of angle-critical accessories, such as polarisers and graduate filters. Consisting of 18 elements in 13 groups, it has an overall length of 194.3 mm and diameter of 89.5 mm. Overall weight is 1.1126 grams and a petal-shaped lens hood is supplied, along with a lightweight and rigid removable alloy tripod socket.  The SP AF70-200mm lens can focus to 95 cm and has a minimum aperture of f/32. It will be available with Canon Nikon, Pentax and Sony lens mounts. Models for Nikon and Canon cameras are equipped with AF/MF switchover mechanisms, permitting one-touch switchover between AF and MF modes. The Sony and Pentax systems require AF/MF switchover operation on both the camera and lens. The new AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro zoom lens is also designed to suit cameras with both full-sized and APS-C sized sensors and provides a zoom ratio of 10.7x plus macro focusing to 49 cm throughout the zoom range. Maximum magnification ratio is 1:3. Consisting of 18 elements in 13 groups, the AF28-300mm lens is 99 mm long with a diameter of 78 mm and overall weight of 550 grams. It is supplied with a petal-shaped lens hood and will be available in Canon and Nikon mounts.  Built-in Vibration Compensation (VC) features a triaxial configuration using three pairs of driving coils that slide balls around the compensator group of the lens’ optical system. Since the compensator lenses are supported with rolling friction of the ball mechanisms, performance is enhanced. Construction is simpler, which results in an ultra-compact lens for its focal range. The lens incorporates a highly accurate gyro sensor for detecting hand-held image shake. This combines with a 32-bit RISC processor to offer the photographer a highly effective anti-vibration effect. The optical system uses a number of lens elements made from special optical glass materials including XR (high refraction index) glass elements, GM (glass-molded aspherical lens) elements, hybrid aspherical elements, LD (low dispersion) glass elements to compensate for on-axis and lateral chromatic aberrations and an AD (anomalous dispersion) glass element. Internal Surface Coatings minimize flare and ghosting and the lens offers high contrast, high resolution performance and flatness of the image field. A zoom lock prevents the barrel from extending when the lens is carried face down. RRPs have not yet been set for either lens.
