Best-in-class MOD (Minimum Object Distance) close-focusing capability

MOD measures just 0.2m (7.9”), yielding a magnification ratio of 1:2.5, the shortest close focusing capability among fast-aperture fixed focal lenses in full-frame format*.

Since the lens allows for shooting at distances extremely close to the subject (similar to a macro), close-up pictures with spectacular background blur effect (bokeh) can be obtained with the aperture wide open, thereby expanding the scope of photo opportunities. Tamron’s proprietary Floating System, which places a group of elements at the optimal location as the focusing group travels relative to shooting distances, ensures the best imaging performance at any range. From the closest distance right through the focal range, image quality is excellent.

* Rated top among current 35mm fixed focal length interchangeable AF lenses for full-frame DSLR cameras excluding macro lenses (as of July 2015; Tamron).

Optimal relative illumination means no dark corners

Some fast-aperture lenses “vignette” or have darkened corners due to uneven light distribution, especially wide open. However, even at the full open aperture, the overall illumination level across the entire field is well balanced and optimized.

eBAND Coating deployed to thoroughly suppress ghosting and flare

eBAND (Extended Bandwidth & Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) coatings, both providing outstanding anti-reflection effect, are applied to critical element surfaces for maximum light transmission. Internal reflections from element surfaces which cause ghosting and flare are reduced to an absolute minimum. Flawless, crystal clear images can be obtained.

eBAND Coating, a hybrid nano-structured layer with extremely low refractive index coupled with multi-layered anti-reflection coating technology, efficiently minimizes reflection of extremely angulated incident light—something that cannot be achieved by conventional anti-reflection coatings alone.

High-speed AF with USD (Ultrasonic Silent Drive)

Fast, quiet AF is achieved by employing a USD ring-type ultrasonic motor which enables remarkably precise focusing drive with high torque and responsiveness. Because the rotational torque of the USD is generated by waves of ultrasonic vibrations, inherent operating noise is extremely low and practically unnoticeable. In addition, Full-time Manual Focus override is available at any point during the autofocus operation for deliberately shifting focus without switching the AF-MF mode back and forth.

Fluorine coating on the front element repels water and fingerprints

Fluorine coating technology, developed for use in industrial optics applications, has been adapted to photographic lenses. The water and oil repellant coating applied to the front element surface allows instant removal of dirt or smudges with ease. The coating also provides a reasonable level of durability, and will sustain its effectiveness for years.

Moisture-resistant construction

Seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops and provide moisture-resistant construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.

Circular aperture for enhanced bokeh

The 9-blade diaphragm retains a nearly circular opening even when stopped down by two stops. Marvellously tuned blur in the subject background can be obtained without generating undesirable shapes of aperture patterns.
