Compensates for camera blur on long shutter speeds – for sharp images in much less light
Tamron's unique VC mechanism uses a proprietary actuator and algorithms to deliver an extremely stable viewfinder image with excellent tracking. The mechanism employs a tri-axial system in which three driving coils move internal optical components within the VC lens electromagnetically, based on signals originating from three steel ball bearings. The VC lens elements are held in place only by contact with the steel balls, achieving smooth movement with minimal friction. The simplicity of this mechanical structure is also one of the secrets of Tamron's compact lens sizes.
Precise, quiet autofocus that allows for fine adjustments
The B011's autofocus mechanism uses a stepping motor that's an ideal match for the contrast detection autofocus system used in Sony NEX series 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
Light & compact
A brilliant match for today's mirrorless interchangeable-lens cameras, the pleasingly small, lightweight B011 provides all the advanced technologies you need to take your photography to the next level. Its impressive 18‒200mm, high-power zoom range can take in everything from casual close-ups to telephoto action images. The more you use this lens, the more you'll want it by your side whether on a quick stroll or on longer journeys.
Tamron's 19 years of high-power zoom technology developments ensure sharp, clear images no matter what you're shooting. Tamron's proprietary VC (Vibration Compensation) image stabilisation lets you capture sharper photos in practically any light, without having to use a tripod. The B011's optical design includes an array of specialised glass elements that overcome a number of aberrations, resulting in crisp, flawless images.*
* The B011's optics include two LD elements, three Glass Molded Aspherical Lenses, one XR (Extra Refractive Index) glass, and one Hybrid Aspherical Lens.
