＜Stepping Motor Schematic Diagram＞
The B011s autofocus mechanism uses a stepping motor thats an
ideal match for the contrast detection autofocus system used in
mirrorless interchangeable-lens cameras. 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 full-time manual focus 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.
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.

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.
* B011 can not be used with digital SLR cameras
with a built-in mirror box or with conventional 35mm film SLR cameras.
* B011 is designed exclusively for APS-C format mirrorless interchangeable-lens cameras.
