Product description
SP (Super Performance)
Only two letters - but what an impact they have on the results. SP stands for Super Performance and represents the high-performance lens class from Tamron. Our engineers were given a free hand in the design of these lenses and left no stone unturned to produce the optimal performance characteristics in each case. Take your camera to new frontiers - and pave the way for Super Performance.
Fluorine coated front element
Because the large diameter and prominent convex profile of the front element does not allow the use of a protective filter, the front element of the lens has a fluorine coating. The coating repels water and dirt, and also makes it much easier to remove smudges.
XGM lens element for exquisite images
The combination of a large diameter XGM (eXpanded Glass Molded Aspherical) with several LD elements in the first lens group of the 18-element, 13-group optical design effectively controls distortion and chromatic aberrations that typically affect wide-angle lenses.
eBAND and BBAR Coating
A new generation of BBAR (Broad-Band Anti-Reflection) Coating has been optimized for ultra-wide angles of view. Together with Tamron’s proprietary eBAND (Extended Bandwidth & Angular-Dependency) Coating which suppresses tangential reflections, they effectively correct ghosting and flare, yielding vivid images of extraordinary clarity.
Vibration Compensation enhances photo opportunities
Responding to the demand for a wide-angle lens suited for handheld shooting at slow shutter speeds, Tamron has created the world's first F/2.8 ultra-wide-angle zoom lens with image stabilization. The result is a lens able to capture sharp images even when shooting handheld under low light conditions.
Soft-focus backgrounds at wide-angle settings
Thanks to its large F/2.8 aperture, this lens lets you soften the foreground or background to dramatically emphasize the subject. It can also capture wide-macro effects with its minimum focus distance of 0.28m over the entire focal-length range.
Resistant to the elements
Moisture-resistant construction helps prevent moisture from penetrating the lens.
Ultrasonic Silent Drive for precise, and quiet autofocus
The quiet high-torque USD motor ensures autofocusing with precision.
