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. The VC lens elements are held in place only by contact with three ball bearings – which in the latest Tamron VC lenses are ceramic – achieving smooth movement with minimal friction. The simplicity of this mechanical structure is also one of the secrets of Tamron's compact lens sizes.
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 polished design and professional metal finish come together in a compact package that is fashionable, ergonomic, supremely portable, and easy to use. Choose from black or silver models to match your camera body.
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.
