Tamron 28-300mm f/3.5-6.3 Aspherical LD IF Macro Autofocus Lens for Minolta Alpha Mount, Silver {72} 285D

A totally new optical system that incorporates three Hybrid Aspherical elements and two high-grade LD (Low Dispersion) glass elements. Together they provide never-before-possible sharpness, contrast and color depth, while eliminating chromatic aberrations inherent to a high-power zoom lens of this magnitude. These state-of-the-art optics are housed in a sophisticated "Quad-Cam Zoom Mechanism" which enables four lens barrels to be extended and retracted effortlessly - achieving compactness at 28mm, while holding precise extension at 300mm.
