The B011's autofocus mechanism uses a stepping motor that's an ideal match for the contrast detection autofocus system used in Sony mirrorless interchangeable-lens camera series. The stepping motor's actuator allows finely tuned control of angular rotation, and since it drives the focusing mechanism directly without an intermediate reduction gear, it also provides superbly quiet performance.

You can count on this to enhance autofocus capability when shooting video. Furthermore, after adjusting with the autofocus mechanism, you can use the Direct Manual Focus (DMF) function to allow delicate adjustments to the image. In short, you can capture the scenes you want, focused exactly as you want them, every time.

The B011 provides a crisp, vivid viewfinder image plus the operational advantages of Tamron's acclaimed VC (Vibration Compensation)* image stabilization technology. This high-power zoom lens enables easy handheld shooting even in low light or at telephoto settings. Tamron's VC technology uses our exclusive, proven, ultra-reliable three-coil system in which three drive coils move the shake-compensating VC optical groups in the lens electromagnetically via three steel balls. This allows the photographer to shoot sharp still images handheld at shutter speeds up to four stops slower than would be possible without VC. The upgraded "moving coil" system in the B011 places the drive coils adjacent to the shake-compensating optics, allowing a lighter, more compact design. The new lens also benefits from design enhancements aimed at providing quieter operation.
* VC is also available in the 17-50mm (B005), 18-270mm (B008), 28-300mm (A20), and 70-300mm (A005) models.
Di III (Digitally integrated design): A designation Tamron gives to lenses engineered specifically for mirrorless interchangeable-lens cameras with no internal mirror box or pentaprism, adopting an optical design that matches the characteristics of the digital camera.
* The B011 can not be used with digital SLR cameras with a built-in mirror box or with conventional 35mm film SLR cameras.
