Realizing both high performance and high image quality, this high-speed standard zoom lens offers 24mm to 70mm coverage together with Tamron’s exclusive VC (Vibration Compensation) system*1 and a USD (Ultrasonic Silent Drive) motor for fast and quiet autofocus.
Since this is an 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 and two XR (Extra Refractive Index) lenses.
The result is best-in-class image quality that reduces various type of distortion. In addition, the F/2.8 high speed and the circular diaphragm construction*2 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.
*1 The Sony mount does not include the VC (Vibration Compensation) system.
*2 The Tamron standard is that the almost-circular diaphragm form should be maintained from wide-open aperture to two stops down.
