|* CIPA Standard Compliant. For Canon: EOS-5D MKIII is used. For Nikon: D810 is used.
High precision AF lets you take steady shots
The AF drive uses proprietary Tamron technology, USD (Ultrasonic Silent Drive) providing high torque, response, and silent operation. Manual focus adjustments can be made on the fly with the lens's Full-time Manual Focus Override system.
The VC mechanism provides powerful support for handheld shooting
New Fluorine Coating for improved durability
The Model A041 has an improved VC (Vibration Compensation) mechanism with vastly better image stabilization performance from the previous Model A012, reaching 4.5 stops according to CIPA standards. This enables sharper images over a wide range of photographic situations, including indoor and outdoor shots as well as landscape photography at stopped-down aperture settings.
The durability of the front element coating is greatly improved with the development of new Fluorine Coating. With the new fluorine compound that has excellent water- and oil-repellent properties, the lens surface is much easier to wipe clean and less vulnerable to damaging effects of dirt, dust, moisture, and fingerprints, and enabling your important lenses to be continually protected on a long-time basis.
The rear filter holder enables greater creative flexibility
A filter holder that allows you to attach gelatin filters to the rear side of the lens is included as a standard feature (for Canon EF-mount only). You can now shoot with filters much more easily, traditionally rather difficult when shooting with ultra-wide-angle lenses with large front lens elements.
Reduce flare and ghosting with eBAND and BBAR
Two highly developed lens coating technologies, eBAND (Extended Bandwidth & Angular-Dependency), which uses nanotechnology, and BBAR (Broad-Band Anti-Reflection) combine to increase light transmission and to reduce flare and ghosting to imperceptible levels. The lens delivers high contrast, sharp and clear images.
Circular Aperture to Produce a Smooth-Edged Bokeh
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background light spots and avoids rugged aperture geometry.
Compatible with the TAMRON TAP-in Console™
The optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens's firmware as well as customize features including fine adjustments to the focus position of AF and VC control.
Moisture-Resistant Construction protects your lens
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
