Your key to beautiful, brilliant video shooting
The Tamron 17-70mm F2.8 APS-C is a standard zoom lens that’s ideal for not only still photography but also for video shooting. The 17-70mm F2.8 has minimal focus breathing, an undesirable phenomenon in which the angle of view changes depending on the focusing distance during videography. By counteracting focus breathing, the 17-70mm F2.8 empowers users’ expression of their creative intentions to the fullest degree. In addition, the quiet RXD AF drive motor and the VC image stabilization mechanism facilitate hand-held video shooting.
TAMRON’s proprietary VC for stable photography and video shooting
The lens includes Tamron’s VC (Vibration Compensation) to reduce camera shake. When shooting video, VC uses AI-based algorithms to optimize stabilization for different scenarios. It’s ideal for handheld video capture and slow shutter shots in low light.
High performance autofocus system means you’ll own every shooting opportunity

RXD stepping motor unit
The lens features Tamron’s RXD (Rapid eXtra-silent stepping Drive) motor. It ensures high-speed, precise, and quiet autofocus—perfect for capturing fast-moving subjects and silent video recording.
