Playing with light, capture a subtle world of beauty. A high-speed standard zoom lens featuring built-in Vibration Compensation. Realizing both high performance & high image quality, this high-speed standard zoom lens offers 24mm to 70mm coverage together with Tamron's exclusive VC (Vibration Compensation) system & a USD (Ultrasonic Silent Drive) motor for fast & quiet autofocus. Since this is a SP (Super Performance) series lens, the optical design places the highest priority on image quality with the extensive use of special optics, including three LD (Low Dispersion) lenses & two XR (Extra Refractive Index) lenses. The result is best-in-class image quality that reduces various types of distortion. In addition, the F/2.8 high speed & the circular diaphragm construction enable this lens to achieve beautiful out-of-focus effects while the high resolution gives finely detailed images. In a Tamron first, a simple drip-proof structure is also featured. This full-spec standard zoom lens responds fully to the inspiration of the photographer.
