The Model A041 is a F/2.8 ultra-wide-angle lens with a focal length starting at 15mm that offers high resolution even in the peripheral area of the image. By incorporating an eXpanded Glass Molded Aspherical lens element and multiple Low Dispersion lens elements to curtail distortion and lateral chromatic aberrations, Tamron has achieved a degree of resolution throughout the range that is just as good as a fixed focal length lens. The Anti-reflection eXpand Coating, especially effective for wide-angle lenses that tend to let in harmful light from peripheral areas, was developed to control rays that affect image quality. The new coating keeps the reflection factor for peripheral areas at the same high level as that for the centre area, not only overcoming standard curvature issues but even overcoming the problems of a conventionally produced convex surface with large curvatures for which uniform deposition has always proved difficult to achieve.
Superb AF speed and precision is delivered by equipping the lens with a Dual Micro-Processing Unit system and employing an enhanced AF control algorithm to improve performance. The AF drive uses proprietary Tamron technology, Ultrasonic Silent Drive, enabling high torque, high response, and silent operation. And because it comes with a Full-time Manual Focus override system, manual focus adjustments can be made on the fly. This lens has been further improved with a newly developed VC mechanism that surpasses former versions and reaches 4.5 stops. This makes it possible to shoot sharp photos over a wide range of photographic scenes as well as handheld shots at stopped-down aperture settings for landscape photography.
