This lightweight and compact lens comes equipped with Tamron's VC (Vibration Compensation) mechanism that leverages AI technology when shooting video, minimizing camera shake.
Outstanding Optical Performance
The optical construction of 17-70mm f/2.8 Lens uses 16 elements in 12 groups. It comprises of two GM (Glass Molded Aspherical) lens elements and one hybrid aspherical lens elements that are precisely arranged to maintain edge to edge resolution.
Upgraded VC with AI for Video Shooting
This 17-70mm f/2.8 Lens features Tamron's proprietary VC mechanism. It utilizes sophisticated algorithms with a dedicated, independently operating MPU that combine to compensate for vibration due to camera shake when shooting handheld. This feature is available when used with both cameras with or without built-in image stabilization. When shooting video, the image stabilization performance is improved thanks to AI technology.
High Performance Autofocus System
This zoom lens comes with an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit that aids in quick, smooth focusing. It uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. When paired with a sensor that precisely detects the position of the lens enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video.
Close Focusing of 7.5 Inches at Wide-Angle End
