The moisture-resistant lens features an XGM (eXpanded Glass Molded Aspherical) and multiple LD (Low Dispersion) lens elements to greatly reduce the distortion and lateral chromatic aberrations often seen in wide-angle photos.
The front of the lens features a new AX (Anti-reflection eXpand) Coating that reduces ghosting and flare. There’s also a Fluorine Coating that provides water- and oil-repellent properties.
Inside, the lens features a built-in Dual MPU (Micro-Processing Unit) for greatly faster autofocus performance and precision. And like its predecessor, this new lens offers image stabilization (4.5 stops).
Full-time Manual Focus override in the lens allows you to make manual focus adjustments at any time.
The Canon EF version of the lens also includes a rear filter holder that supports gelatin and other sheet filters.

“This makes photography using filters much easier and simpler by overcoming the problem of the curvature of the front lens elements that made shooting with filters so difficult in the past,” Tamron says.
As with Tamron’s other new lenses, this new lens is compatible with the company’s TAP-in Console for making firmware updates and fine focus adjustments via USB using your own computer.
