Tamron's next generation 18 to 270mm world’s lightest, smallest 15x zoom optimized lens 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 to 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-friction 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. Defining compositional freedom the 18 to 270mm Di-II VC's incredible 15x zoom range provides a 35mm picture angle equivalency of 28 to 419mm, with image fidelity assured by advanced optical design featuring LD glass and aspherical optics, working in concert to render crisp, colorful and faithful images.
