Tamron 18-200mm f/3.5-6.3 Di III VC, E Mount
The tamron 18-200mm f/3.5-6.3 Di III VC Lens made for the sony E mount camera
system incorporates a stepping motor that is optimal for the contrast-detection
AF system of sony mirrorless interchangeable-lens cameras. This will also
improve AF when shooting video. With the motor built into the lens, focusing
will be quieter and more responsive.
