Tamron announces 15x zoom lens

Superzoom specialist Tamron has today announced the development of its most ambitious lens yet, the characteristically snappily-titled AF 18-270mm F/3.5-6.3 Di II VC LD Aspherical (IF) Macro. Designed exclusively for digital SLRs with APS-C sensors, this optic offers a 35mm-equivalent range of 28-419mm, perfect for owners of megazoom compacts looking to upgrade to an SLR, and incorporates the company’s ‘Vibration Control’ optical image stabilisation system. To achieve the spectacular zoom range (billed as the longest in the world),Tamron has used all its design nous, including the use of aspheric elements and low dispersion glass to keep chromatic aberration under control.
