Ultra-Wide Performance & Macro Versatility
20mm Perspective: Experience a dramatic ultra-wide field of view on full-frame bodies, or use it on APS-C models for a useful 30mm equivalent focal length.
1:2 Macro Reproduction: Unlike standard wide-angle lenses, this prime offers a half life-size 1:2 magnification ratio. With a remarkably close 4.3″ minimum focusing distance, you can capture stunning close-ups with an expansive background.
Compact & Lightweight: The f/2.8 maximum aperture allows for a svelte, portable design that won’t weigh down your kit during long days of travel or street photography.
Advanced Optical Layout: Featuring three Low Dispersion (LD) elements and one molded glass aspherical element, the lens is engineered to suppress chromatic aberrations and distortion for edge-to-edge sharpness.
Reliable Build & Precision Focus
OSD Stepping Motor: The Optimized Silent Drive (OSD) motor provides fast, quiet, and precise autofocus performance, making it suitable for both high-resolution stills and video work.
Weather-Ready Design: The lens features a moisture-resistant construction for peace of mind in inclement weather. A fluorine coating on the front element provides extra protection against dust, water, and fingerprints.
BBAR Coating: Tamron’s Broad-Band Anti-Reflection coating reduces flare and ghosting, ensuring your images maintain high contrast and color accuracy even when shooting toward the sun.
7-Blade Rounded Diaphragm: Produces a smooth and pleasing background blur, perfect for isolating close-up subjects against a wide-angle vista.
Included Accessories
Lens Hood: This unit includes the dedicated lens hood to further prevent stray light from causing flare and to provide added physical protection for the front element.
