Tamron's next generation 18-270mm, the world's lightest, smallest 15x zoom optimized for use on APS-C- DSLRs, continues the pursuit of the ideal all-in one zoom lens. Combining prior award-winning achievements with new engineering breakthroughs yielded the remarkable 18-270mm F/3.5-6.3 Di II VC PZD (Piezo Drive). Special piezoelectric technology now delivers faster, quieter precision autofocusing. Tamron's exclusive tri-axial VC (Vibration Compensation) image stabilization, featuring three pairs of driving coils and low-function ball bearings placed around the VC optical group, combats camera shake-related image blur. It's Tamron VC that allows handheld shooting at as many as four shutter speeds slower than otherwise possible with a dramatically stable viewfinder experience. Compactness and light weight are preserved, thanks in part to the VC mechanism's newly-developed moving coil mechanism.
