The optical design includes 16 elements in 11 groups. A new large aperture aspherical lens and LD (Low Dispersion) lens elements deliver exceptional resolution across the complete zoom range— combined with stable imaging across the entire frame. The lens also corrects comatic and transverse chromatic aberration, as well as distortion that often crops up on other wide-angle lenses. Together with Tamron’s unique BBAR (Broad-Band Anti-Reflection) Coating, which improves light transmission and suppresses reflection and dispersion on the lens surface, this new ultra-wide-angle zoom has been entirely reimagined to control flare and ghosting. The result: clear, crisp images, every time.
